Pinhole Results

In my last couple of posts I described making and shooting with a pinhole attachment for my 35mm Pentax P30t SLR. Well, the scans are now back from the lab and I’m very pleased with them. They were shot on Fujifilm Superia Xtra 400.

As suspected, the 0.7mm pinhole was far too big, and the results are super-blurry:

See how contemptuous Spike is of this image. Or maybe that’s just Resting Cat Face.

The 0.125mm hole produced much better results, as you can see below. My f/stop calculations (f/365) seem to have been pretty close to the mark, although, as is often the case with film, the occasions where I gave it an extra stop of exposure produced even richer images. Exposure times for these varied between 2 and 16 seconds. Click to see them at higher resolution.

I love the ethereal, haunting quality of all these pictures, which recalls the fragility of Victorian photographs. It’s given me several ideas for new photography projects…

Pinhole Results

Adventures with a Pinhole

Last week I discussed making a pinhole for my Pentax 35mm SLR. Since then I’ve made a second pinhole and shot a roll of Fujifilm Superia X-tra 400 with them. Although I haven’t had the film processed yet, so the quality of the images is still a mystery, I’ve found shooting with a pinhole to be a really useful exercise.

A Smaller Pinhole

Soon after my previous post, I went out into the back garden and took ten exposures of the pond and the neighbour’s cat with the 0.7mm pinhole. By that point I had decided that the hole was almost certainly too big. As I noted last week, Mr Pinhole gives an optimal diameter of 0.284mm for my camera. Besides that, the (incredibly dark) images in my viewfinder were very blurry, a sign that the hole needed to be smaller.

Scans of my two pinholes

So I peeled the piece of black wrap with the 0.7mm pinhole off my drilled body cap and replaced it with another hole measuring about 0.125mm. I had actually made this smaller hole first but rejected it because absolutely nothing was visible through the viewfinder, except for a bit of a blur in the centre. But now I came to accept that I would have to shoot blind if I wanted my images to be anything approaching sharp.

The 0.125mm(ish) pinhole magnified in Photoshop

I had made the 0.125mm hole by tapping the black wrap with only the very tip of the needle, rather than pushing it fully through. Prior to taping it into the body cap, I scanned it at high resolution and measured it using Photoshop. This revealed that it’s a very irregular shape, which probably means the images will still be pretty soft. Unfortunately I couldn’t see a way of getting it any more circular; sanding didn’t seem to help.

Again I found the f-stop of the pinhole by dividing the flange focal distance (45.65mm) by the hole diameter, the result being about f/365. My incident-light meter only goes up to f/90, so I needed to figure out how many stops away from f/365 that is. I’m used to working in the f/1.4-f/22 range, so I wasn’t familiar with how the stop series progresses above f/90. Turns out that you can just multiply by 1.4 to roughly find the next stop up, so after f/90 it’s 128, then 180, then 256, then 358, pretty close to my f/365 pinhole. So whatever reading my meter gave me for f/90, I knew that I would need to add 4 stops of exposure, i.e. multiply the shutter interval by 16. (Stops are a base 2 logarithmic scale. See my article on f-stops, T-stops and ND filters for more info.)

 

The Freedom of Pinhole Shooting

I’ve just spent a pleasant hour or so in the garden shooting the remaining 26 exposures on my roll with the new 0.125mm pinhole. Regardless of how the photos come out, I found it a fun and fascinating exercise.

Knowing that the images would be soft made me concentrate on colour and form far more than I normally would. Not being able to frame using the viewfinder forced me to visualise the composition mentally. And as someone who finds traditional SLRs very tricky to focus, it was incredibly freeing not to have to worry about that, not to have to squint through the viewfinder at all, but just plonk the camera down where it looked right and squeeze the shutter.

Of course, before squeezing the shutter I needed to take incident-light readings, because the TTL (through the lens) meter was doing nothing but flash “underexposed” at me. Being able to rely solely on an incident meter to judge exposure is a very useful skill for a DP, so this was great practice. I’ve been reading a lot about Ansel Adams and the Zone System lately, and although this requires a spot reflectance meter to be implemented properly, I tried to follow Adams’ philosophy, visualising how I wanted the subject’s tones to correspond to the eventual print tones. (Expect an article about the Zone System in the not-too-distant future!)

 

D.I.Y. pinhole Camera

On Tuesday night I went along to a meeting of Cambridge Darkroom, the local camera club. By coincidence, this month’s subject was pinhole cameras. Using online plans, Rich Etteridge had made up kits for us to construct our own complete pinhole cameras in groups. I teamed up with a philosophy student called Tim, and we glued a contraption together in the finest Blue Peter style. The actual pinholes were made in metal squares cut from Foster’s cans, which are apparently something Rich has in abundance.

DIY pinhole camera

I have to be honest though: I’m quite scared of trying to use it. Look at those dowels. Can I really see any outcome of attempting to load this camera other than a heap of fogged film on the floor? No. I think I’ll stick with my actual professionally-made camera body for now. If the pinhole photos I took with that come out alright, then maaaaaaybe I’ll consider lowering the tech level further and trying out my Blue Peter camera. Either way, big thanks to Rich for taking all that time to produce the kits and talk us through the construction.

Watch this space to find out how my pinhole images come out.

Adventures with a Pinhole

The Normal Lens

Today I’m investigating the so-called normal (a.k.a. standard) lens, finding out exactly what it is, the history behind it, and how it’s relevant to contemporary cinematographers.

 

The Normal lens in still photography

A normal lens is one whose focal length is equal to the measurement across the diagonal of the recorded image. This gives an angle of view of about 53°, which is roughly equivalent to that of the human eye, at least the angle within which the eye can see detail. If a photo taken with a normal lens is printed and held up in front of the real scene, with the distance from the observer to the print being equal to the diagonal of the print, then objects in the photo will look exactly the same size as the real objects.

Asahi Pentax-M 50mm/f1.4 – a normal lens for 35mm stills

Lenses with a shorter focal length than the normal are known as wide-angle. Lenses with a greater focal length than the normal are considered to be long lenses. (Sometimes you will hear the term telephoto used interchangeably with long lens, but a telephoto lens is technically one which has a focal length greater than its physical length.)

A still 35mm negative is 43.3mm across the diagonal, but this got rounded up quite a bit — by Leica inventor Oskar Barnack — so that 50mm is widely considered to be the normal lens in the photography world. Indeed, some photographers rarely stray from the 50mm. For some this is simply because of its convenience; it is the easiest length of lens to manufacture, and therefore the cheapest and lightest. Because it’s neither too short nor too long, all types of compositions can be achieved with it. Other photographers are more dogmatic, considering a normal lens the only authentic way to capture an image, believing that any other length falsifies or distorts perspective.

 

The normal lens in cinematography

SMPTE (the Society of Motion Picture and Television Engineers), or indeed SMPE as it was back then, decided almost a century ago that a normal lens for motion pictures should be one with a focal length equal to twice the image diagonal. They reasoned that this would give a natural field of view to a cinema-goer sitting in the middle of the auditorium, halfway between screen and projector (the latter conventionally fitted with a lens twice the length of the camera’s normal lens).

A Super-35 digital cinema sensor – in common with 35mm motion picture film – has a diagonal of about 28mm. According to SMPE, this gives us a normal focal length of 56mm. Acclaimed twentieth century directors like Hitchcock, Robert Bresson and Yasujiro Ozu were proponents of roughly this focal length, 50mm to be more precise, believing it to have the most natural field of view.

Of course, the 1920s SMPE committee, living in a world where films were only screened in cinemas, could never have predicted the myriad devices on which movies are watched today. Right now I’m viewing my computer monitor from a distance about equal to the diagonal of the screen, but to hold my phone at the distance of its diagonal would make it uncomfortably close to my face. Large movie screens are still closer to most of the audience than their diagonal measurement, just as they were in the twenties, but smaller multiplex screens may be further away than their diagonals, and TV screens vary wildly in size and viewing distance.

 

The new normal

To land in the middle of the various viewing distances common today, I would argue that filmmakers should revert to the photography standard of a normal focal length equal to the diagonal, so 28mm for a Super-35 sensor.

Deleted scene from “Ren: The Girl with the Mark” shot on a vintage 28mm Pentax-M

According to Noam Kroll, “Spielberg, Scorsese, Orson Wells, Malick, and many other A-list directors have cited the 28mm lens as one of their most frequently used and in some cases a favorite [sic]”.

I have certainly found lenses around that length to be the most useful on set.  A 32mm is often my first choice for handheld, Steadicam, or anything approaching a POV. It’s great for wides because it compresses things a little and crops out unnecessary information while still taking plenty of the scene in. It’s also good for mids and medium close-ups, making the viewer feel involved in the conversation.

When I had to commit to a single prime lens to seal up in a splash housing for a critical ocean scene in The Little Mermaid, I quickly chose a 32mm, knowing that I could get wides and tights just by repositioning myself.

A scene from “The Little Mermaid” which I shot on a 32mm Cooke S4

I’ve found a 32mm useful in situations where coverage was limited. Many scenes in Above the Clouds were captured as a simple shot-reverse: both mids, both on the 32mm. This was done partly to save time, partly because most of the sets were cramped, and partly because it was a very effective way to get close to the characters without losing the body language, which was essential for the comedy. We basically combined the virtues of wides and close-ups into a single shot size!

In addition to the normal lens’ own virtues, I believe that it serves as a useful marker post between wide lenses and long lenses. In the same way that an editor should have a reason to cut, in a perfect world a cinematographer should have a reason to deviate from the normal lens. Choose a lens shorter than the normal and you are deliberately choosing to expand the space, to make things grander, to enhance perspective and push planes apart. Select a lens longer than the normal and you’re opting for portraiture, compression, stylisation, maybe even claustrophobia. Thinking about all this consciously and consistently throughout a production can add immeasurably to the impact of the story.

“The Knowledge”: Shooting a Multi-camera Game Show

Last week saw the UK premier of The Knowledge, an art installation film, at the FLUX Exhibition hosted by Chelsea College of Arts. Conceived by award-winning, multi-disciplinary artist Ian Wolter, The Knowledge comments on the topical issue of artificial intelligence threatening jobs. It takes the form of a fake game show, pitting a team of traditional London cabbies (schooled in the titular Knowledge) against a team of smart-phoning minicab drivers. Although shot entirely on stage, the film’s central conceit is that the teams are each guiding a driver across London, to see whether technology or human experience will bring its car to the finish line first.

You can see a couple of brief promos on Vimeo here. It’s a unique project, and one that I knew would be an interesting challenge as soon as I heard of it from my friend Amanda Stekly, producer and production designer. This week and next I’ll describe the creative and technical decisions that went into photographing the piece, beginning this week with the camera side of things.

Photo: Laura Radford

I had never shot a multi-camera studio production like this before, so my first move was to sit down with my regular 1st AC and steadicam operator Rupert Peddle, and his friend Jack D’Souza-Toulson. Jack has extensive experience operating as part of a multi-camera team for live TV and events. This conversation answered such basic questions as, could the operators each pull their own focus? (yes) and allowed me to form the beginnings of a plan for crew and kit.

Ian and Amanda wanted the film to have a dated look, and referenced such eighties quiz shows as 3-2-1 and Blankety Blank. Director Jonnie Howard and I knew that we had to supply the finished film in HD, which ruled out shooting on vintage analogue video cameras. Interlaced recording was rejected for similar reasons, though if memory serves, I did end up shooting at a shutter angle of 360 degrees to produce a more fluid motion suggestive of interlaced material.

I was very keen that the images should NOT look cinematic. Jonnie was able to supply two Canon C100s – which I’ve always thought have a sharp, “video-ish” look – and L-series glass. I set these to 1600 ISO to give us the biggest possible depth of field. For the remaining two cameras, I chose ENG models, a Canon XF-300 (owned by Rupert) and XF-305. In an ideal world, all four cameras would have been ENG models, to ensure huge depth of field and an overall TV look, but some compromise was necessary for budget reasons, and at least they all used Canon sensors. We hired a rack of four matching 9″ monitors so we could ensure a consistent look on set.

One Canon C100, with an L-series zoom, was mounted on a pedestal and outfitted with Rupert’s follow focus system, allowing Jack to pull focus from the panning handle. The other C100 would shoot a locked-off wide, and was the first camera to be set up. A 14mm Samyang lens made the set look huge, and I placed it low down to emphasise the map in the foreground, and to make it easy for the other cameras to shoot over it. Once that frame was set, we taped a large V shape on the floor to indicate the edges of the wide shot. As long as the lights and other cameras stayed out of that area, they would be safe.

Generally Jack’s pedestal-mounted C100 followed the host, Robert Jezek, or captured the interesting moving shots, while Rupert and the third operator, Jimmy Buchanan, cross-shot the two teams on the XF-100 and XF-105. No filtration was used, except for a four-point star filter on one camera when glitter canons are fired at the end of the game. This cheesiness was inspired by the 3-2-1 clips I watched for research, in which star filters were used for the tacky sequences showing the prizes on offer.

Next week I’ll discuss lighting the show. Meanwhile, find out more about Ian’s work at ianwolter.com.

“The Knowledge”: Shooting a Multi-camera Game Show

If Camera was Sound and Sound was Camera

“Sound has the set,” calls the 1st AD, fishing a roll-up from her pocket and heading for the fire exit.

The production sound mixer strides into the middle of the set and strokes his Hipster beard thoughtfully.

“What are you thinking, boss?” asks the gaffer, scratching at the beer belly under his Yamaha t-shirt.

The mixer points to the skylight. “Let’s have some early morning ambience coming through here – the one with the distant traffic.” With a sweeping gesture he encompasses one side of the kitchen set. “I want it to explode off the floor and reverberate throughout this whole area.”

“Hundred watt woofer?” the gaffer suggests. The mixer nods, and a spark scuttles off to the truck for the required speaker.

“Is that practical?” the mixer wonders aloud. The gaffer follows his gaze to the kettle, nods, and flicks the switch. The mixer pulls a sound meter from the pocket of his leather jacket and holds it up to the boiling appliance. “6dB under.”

“We could hide a little tweeter behind it, bring the level up a bit,” the gaffer suggests. “I’ve got half a dozen different kettle effects on the truck.”

The mixer agrees, and proceeds to point out several other positions around the set, which is soon full of busy sparks running XLR cables, rigging speakers and shaping them with sound blankets. A cacophony grows as each one is fired up.

“Does this look about right?” asks the 1st AS, steadying the Sennheiser as the grips wheel its massive Technoboom to the previously agreed spot. She holds a pair of headphones out to the mixer.

He puts them on, and a reverent hush descends upon the set. He pans the mic left, then right, then up, then down, then left and right again. Finally he takes off the cans, clutching at his SQN baseball cap to stop it coming off too. “We need to go tighter,” he pronounces. He holds up his two hands, forming a circular aperture with his fingers, and cups them around his ear. His face a picture of concentration, he squats down and listens intently through the hole in his hands. He shuffles a little to the left. “This is it. We need to be right here on the 67.”

“Copy that,” the 1st AS replies. Her 2nd drags over a massive flight case and she begins unscrewing the ME66 from the power module.

 

“OK everyone, standby for a mic rehearsal.”

At last the camera operator – who had been somehow hiding in plain sight – puts down his coffee and heaves an Alexa onto his shoulder, checking the image as the cast go through the motions.

The director presses her headphones against her ears, frowning. She turns to the mixer. “I’m not getting enough sense of where they are,” she says. “Can we go wider?”

A few moments later the 1st AS is sighing as she unscrews the ME67 and remounts the ME66.

“It’s really quiet,” a producer complains, from his canvas chair in front of the amp at sound city. “Can we turn it up a bit?”

“We’ve got to have the mood,” the mixer insists. “What you can’t hear is more exciting than what you can.”

“I’m paying to hear it!” snaps the producer. “And why is there so much hiss? I can barely hear the dialogue over it.”

“It’s atmosphere!” the mixer protests, but he can see he’s not going to win this one. Reluctantly he signals a spark to turn down the white noise generator.

 

“Cut!” calls the director, smiling in satisfaction at the cast. She turns to the mixer. “How was that for you?”

“That sounded beautiful,” he replies ecstatically.

“OK, moving on,” says the AD, reaching for the clip-list.

“Hang on a minute.”

All eyes turn to the camera op.

“The caterer walked through the back of shot.”

“Did he?” asks the AD, looking around the crew for confirmation.

“I didn’t pick him up,” says the mixer.

The camera op stares at them in disbelief. “He sauntered right across the back of the set. He was there the whole take. It’s completely unusable.”

The AD sighs. “I guess we’d better go again.”

“Can we ask people not to walk through the frame? This lens will pick up literally anyone that walks in front of it.”

The director thinks about this. “Have you got a different lens you can use?”

“Can’t you put Go Pros on them?” asks the AD, gesturing to the cast.

“I’d rather not use Go Pros,” a new voice chimes in. Everyone turns with surprise to see the director of photography blinking in the light. She almost never moves from the shadowy corner where she sits with LiveGrade and a monitor which is rumoured to display mostly rugby matches.

“We can’t afford to lose any more takes because of camera,” says the AD. “What’s wrong with Go Pros anyway?”

“The image just isn’t as good. The dynamic range…”

But the AD cuts her short. “Well, it’s either that or AVR.”

“I just think if we took thirty seconds to find a new position for the Alexa…”

As the producer strides over to stick his oar in, the sound assistants exchange knowing looks: this could go on for a while. The pair lean on the Magliner and check their phones.

“Have you ever worked with a Nagra?” the 2nd AS asks, conversationally. “I still think they sound better than digital.”

If Camera was Sound and Sound was Camera

Camerimage 2017: Wednesday

This is the third and final part of my report from my time at Camerimage, the Polish film festival focused on cinematography. Read part one here and part two here.

 

Up.Grade: Human Vision & Colour Pipelines

I thought I would be one of the few people who would be bothered to get up and into town for this technical 10:15am seminar. But to the surprise of both myself and the organisers, the auditorium of the MCK Orzeł was once again packed – though I’d learnt to arrive in plenty of time to grab a ticket.

Up.grade is an international colour grading training programme. Their seminar was divided into two distinct halves: the first was a fascinating explanation of how human beings perceive colour, by Professor Andrew Stockman; the second was a basic overview of colour pipelines.

Prof. Stockman’s presentation – similar to his TED video above – had a lot of interesting nuggets about the way we see. Here are a few:

  • Our eyes record very little colour information compared with luminance info. You can blur the chrominance channel of an image considerably without seeing much difference; not so with the luminance channel.
  • Light hitting a rod or cone (sensor cells in our retinae) straightens the twist in the carbon double bond of a molecule. It’s a binary (on/off) response and it’s the same response for any frequency of light. It’s just that red, green and blue cones have different probabilities of absorbing different frequencies.
  • There are no blue cones in the centre of the fovea (the part of the retina responsible for detailed vision) because blue wavelengths would be out of focus due to the terrible chromatic aberration of our eyes’ lenses.
  • Data from the rods and cones is compressed in the retina to fit the bandwidth which the optical nerve can handle.
  • Metamers are colours that look the same but are created differently. For example, light with a wavelength of 575nm is perceived as yellow, but a mixture of 670nm (red) and 540nm (green) is also perceived as yellow, because the red and green cones are triggered in the same way in both scenarios. (Isn’t that weird? It’s like being unable to hear the difference between the note D and a combination of the notes C and E. It just goes to show how unreliable our senses really are.)
  • Our perception of colour changes according to its surroundings and the apparent colour of the lighting – a phenomenon perfectly demonstrated by the infamous white-gold/blue-black dress.

All in all, very interesting and well worth getting out of bed for!

At the end of the seminar I caught up with fellow DP Laura Howie, and her friend Ben, over coffee and cake. Then I sauntered leisurely to the Opera Nova and navigated the labyrinthine route to the first-floor lecture theatre, where I registered for the imminent Arri seminar.

 

Arri Seminar: International Support Programme

After picking up my complementary Arri torch, which was inexplicably disguised as a pen, I bumped into Chris Bouchard. Neither of us held high hopes that the Support Programme would be relevant to us, but we thought it was worth getting the lowdown just in case.

Shooting “Kolkata”

The Arri International Support Programme (ISP) is a worldwide scheme to provide emerging filmmakers with sponsored camera/lighting/grip equipment, postproduction services, and in some cases co-production or sales deals as well. Mandy Rahn, the programme’s leader, explained that it supports young people (though there is no strict age limit) making their first, second or third feature in the $500,000-$5,000,000 budget range. They support both drama and documentary, but not short-form projects, which ruled out any hopes I might have had that it could be useful for Ren: The Girl with the Mark.

Having noted these keys details, Chris and I decided to duck out and head elsewhere. While Chris checked out some cameras on the Canon stand, I had a little chat with the reps from American Cinematographer about some possible coverage of The Little Mermaid. We then popped over to the MCK and caught part of a Canon seminar, including a screening of the short documentary Kolkata. Shortly we were treading the familiar path back to the Opera Nova and the first-floor lecture theatre for a Kodak-sponsored session with Ed Lachman, ASC, only to find it had been cancelled for reasons unknown.

 

Red Seminar: High resolution Image Processing Pipeline

Next on our radar was a Red panel. I wasn’t entirely sure if I could handle another high resolution seminar, but I suggested we return once more to the MCK anyway and relax in the bar with one eye on the live video feed. Unfortunately we got there to find that the monitors had disappeared, so we had to go into the auditorium, where it was standing room only.

“GLOW” – DP: Christian Sprenger

Light Iron colourist Ian Vertovec was talking about his experience grading the Netflix series GLOW, a highly enjoyable comedy-drama set behind the scenes of an eighties female wrestling show. Netflix wanted the series delivered in high dynamic range (HDR) and wide colour gamut (WCG), of a spec so high that no screens are yet capable of displaying it. In fact Vertovec graded in P3 (the colour space used for cinema projection) which was then mapped to Netflix’s higher specs for delivery. The Rec.709 (standard gamut) version was automatically created from the P3 grade by Dolby Vision software which analysed the episodes frame by frame. Netflix streams a 4,000 NIT signal to all viewers, which is then down-converted live (using XML data also generated by the Dolby Vision software) to 100, 650 or 1,000 NITs depending on their display. In theory this should provide a consistent image across all screens.

Vertovec demonstrated his image pipeline for GLOW: multi-layer base grade, halation pass, custom film LUT, blur/sharp pass, grain pass. The aim was to get the look of telecined film. The halation pass involved making a copy of the image, keying out all but the highlights, blurring those highlights and layering them back on top of the original footage. I used to do a similar thing to soften Mini-DV footage back in the day!

An interesting point was made about practicals in HDR. If you have an actor in front of or close to a practical lamp in frame, it’s a delicate balancing act to get them bright enough to look real, yet not so bright that it hurts your eyes to look at the actor with a dazzling lamp next to them. When practicals are further away from your cast they can be brighter because your eye will naturally track around them as in real life.

Next up was Dan Duran from Red, who explained a new LUT that is being rolled out across their cameras. Most of this went in one ear and out the other!

 

“Breaking Bad”

Afterwards, Chris and I returned to Kung Fusion for another delicious dinner. The final event of the day which I wanted to catch was Breaking Bad‘s pilot episode, screening at Bydgoszcz’s Vue multiplex as part of the festival’s John Toll retrospective. Having binged the entire series relatively recently, I loved seeing the very first episode again – especially on the big screen – with the fore-knowledge of where the characters would end up.

Later Chris introduced me to DP Sebastian Cort, and the three of us decided to try our luck at getting into the Panavision party. We snuck around the back of the venue and into one of the peripheral buildings, only to be immediately collared by a bouncer and sent packing!

This ignoble failure marked the end of my Camerimage experience, more or less. After another drink or two at Cheat we called it a night, and I was on an early flight back to Stansted the next morning. I met some interesting people and learnt a lot from the seminars. There were some complaints that the festival was over-subscribed, and indeed – as I have described – you had to be quick off the mark to get into certain events, but that was pretty much what I had been expecting. I certainly won’t put be off attending again in the future.

To learn more about two of the key issues raised at this year’s Camerimage, check out my Red Shark articles:

Camerimage 2017: Wednesday

Camerimage 2017: Tuesday

This is the second part of my report from my time at Camerimage, the Polish film festival focused on cinematography. Read part one here.

 

Panavision: The BEauty of 8K Large Format

Bydgoszcz’s town square

It was a chilly but bright morning as I strolled into Bydgoszcz and made straight for the MCK Orzeł, where I planned to spend most of the day. With only a few minutes to go until the scheduled start time, the queue for Panavision’s large format seminar had spilt out onto the street. The tickets ran out before I reached the desk, but there was a live video feed in the cinema’s bar. In many ways this was better than going into the auditorium – sitting in a comfy chair with the bar close at hand, and a table to make notes on.

My article for Red Shark News about the future of large format cinematography has been surprisingly popular, and it contains plenty of detail about this Panavision seminar, so I won’t repeated myself here. I will say that it converted me from a high resolution sceptic to a believer, because the speakers demonstrated that footage acquired in high rez – even when downscaled – retain much of its smoothness, high bit depth and dynamic range. “More resolution evokes the imagination of the brain,” was how colourist Ian Vertovec summed it up.

At the end of the session, Red Shark’s David Shapton and Matt Gregory emerged from the auditorium and joined me for lunch at the bar. We had all found the seminar very interesting, and Matt was quick to get us all tickets to the Panasonic 4K seminar coming up later in the day. The pair then went off to other things, while I headed to the kiosk to get a ticket for the imminent John Toll seminar. But of course I’d left it too late, they were all gone, and so I returned to my comfy chair in the bar to watch via video feed again.

 

Panavision workshops: A conversation with John Toll, ASC

John Toll, ASC

John Toll, ASC was the recipient of this year’s Lifetime Achievement Award at Camerimage, and this seminar was an epic journey through this career. He explained how he learnt his craft as a camera operator for the late great Conrad Hall, ASC and Jordan Cronenweth, ASC.

The talk then focused on some of Toll’s biggest movies, beginning with the period drama Legends of the Fall starring Brad Pitt and Anthony Hopkins. The movie was largely daylight exterior (something that was to become a theme across Toll’s work) so the cinematographer insisted on twelve weeks of prep, the same as the production designer. This allowed him to be part of selecting locations and choosing orientations for the buildings to get the optimal sun path. Toll said he was lucky that the 1st AD was willing to be flexible with the schedule, observing the mood of the weather each day and shooting scenes that matched that mood.

Gaffer Jim Plannette joined Toll on the stage to discuss the huge night exterior battle sequence. This employed three Musco lights (a Musco being fifteen 6K pars on a 100ft boom arm) which three-quarter-backlit every angle. To get crisp, grain-free blacks, Toll overexposed and printed down.

Braveheart was covered next, with 1st AC Graham Hall joining the panel. Hall had a difficult time with the film’s battle scenes, featuring as they did so much movement, improv and slo-mo. Toll revealed how the immersive style of the action was based on a sixties TV documentary about Culloden that coincidentally both he and director Mel Gibson had seen. A lot of colour timing was required to give consistency to the battles, which were shot over weeks, at all times of day.

The discussion then turned to Terrence Malick’s The Thin Red Line. The Australian locations featured very difficult, uneven terrain, so Toll used an Akela Crane. The crane’s arm was so long (75ft) that the arc of its movement couldn’t be detected on camera. Its use had to be carefully planned though, because each time it needed to be moved it had to be disassembled and reassembled on a special platform. 80% of the film was actually handheld, and Toll operated himself so as to respond to the spontaneity and improv which Malick encourage from his cast.

Toll told a funny story about a shot of shadows moving across long grass which was praised by critics. It was inserted to cover a continuity error, the build-up to the battle having been shot in heavy cloud, while the battle itself was shot in full sun. A happy accident!

Time was running short, so the moderator powered through Almost Famous (where parallels were drawn between the explosive battle scenes of Toll’s earlier movies and the crowd scenes at the rock concerts, punctuated by flashing cameras), Vanilla Sky and Billy Lynn’s Long Halftime Walk. This latter film, directed by Ang Lee, is notable for its acquisition in 120fps 4K stereo. You can read more about it on the British Cinematographer website.

 

Panasonic Seminar: Varicam Experience

A Panasonic Varicam LT with Fujinon zoom rigged for action on “Arrested Development”

I remained at the MCK and, meeting up with Dave and Matt again, finally got into the auditorium, for the Panasonic seminar. Moderated by British Cinematographer‘s Ronnie Prince, the panel brought together a trio of DPs who shoot Netflix shows on the Varicam: Bobby Shore, CSC (Anne with an E), Pepe Avila del Pino (Ozark) and Patrick Alexander Stewart (Arrested Development).

Both Shore and del Pino admitted that they were most comfortable with the Arri Alexa, but due to Netflix’s strict rules on 4K acquisition (the Alexa tops out at 3.2K) they had to find another camera. They plumped for the Panasonic Varicam, a 4K camera best known for having dual native ISOs: 800, in common with the Alexa, Red and many others, and 5000, two and two-thirds stops faster. Being native, both ISOs have the same dynamic range, the same log curve and in theory are equally clean.

Panasonic, I think, were keen to push ISO 5000 in this seminar, but unfortunately Shore and del Pino shot almost exclusively at 800. Stewart did shoot Arrested Development at 5000, interiors and night scenes at least, but down-rated it to 2500. Otherwise, he said, the sets would have been too dark for the actors to feel like they were in a believable daytime environment. I think that’s a fascinating, unexpected side effect of low light sensitivity! Stewart lit the stages with large Quasar softboxes and paired the Varicam with Fujinon zooms and occasional Xeen primes.

Del Pino chose Zeiss Super Speeds for night scenes and Hawk V anamorphics for day scenes on Ozark. He liked the claustrophobia of cropping the anamorphic images to 2:1, the show’s delivery ratio, while the Super Speeds produced a creaminess he found appealing. He also mentioned that the Varicam’s sensor handled greens very well, which was important for him, given how much of Ozark takes places in woods.

Anne with an E was lensed on vintage Panavision Standard and Super Speeds – “the oldest, craziest lenses we could find,” says Bobby Shore. He liked their low resolving power, their weird flares and how they fell apart when wide open. Part of the show’s signature look are ECUs of the freckled title character, which were captured on a 27mm Primo for a more detailed, tactile image.

Inspired by the work of Robbie Ryan, BSC (Wuthering Heights), Shore kept the lighting naturalistic, mixing tungsten and HMI sources on a set that was treated like a location. He also shot through a Panaflasher, a special lens filter with built-in lighting which reduces contrast and adds a colour tint of your choice, but this effect was dialled out in post. Indeed, Shore raised the issue of DPs’ images being altered after the fact, an issue I explore fully in another Red Shark article.

By the way, I’ve been watching Anne with an E since the festival and I can thoroughly recommend it.

When the seminar was over, I went for dinner with Dave, Matt and Chris Bouchard, at a very nice (but once again cheap) Asian fusion restaurant. Then we met up for drinks with some of the reps from Red, and I got talking to a DP who had shot squid from a submarine for an episode of Blue Planet. After another drink or two with Chris at the Cheat bar, I called it a night.

Tune in next week for the final part of my Camerimage blog.

Camerimage 2017: Tuesday

Camerimage 2017: Monday

This week I attended Camerimage for the first time. Centred around the Opera Nova theatre beside the river Brda in Bydgoszcz, Poland, Camerimage is an international film festival celebrating the art of cinematography. It’s a bit like Cannes for DPs, but colder. This is the first part of my account of my three days at the annual hub of motion picture imaging.

The Ryanair flight was dirt cheap but trouble free, and at 9:50am I found myself on the tarmac of Bydgoszcz airport. There I met David Shapton and Matt Gregory, founders of Red Shark News, for the first time. I’ve been contributing articles to Red Shark for a few months so it was nice to finally meet these gentlemen in person.

A taxi (also dirt cheap) dropped me at the Opera Nova – only about three miles from the airport – where I picked up my pass and goodie bag. Bizarrely, said goodies included an Ikea catalogue. How did they know that us DPs love flat-pack furniture so much?

 

Canon Workshop: Stephen Goldblatt

From the Opera Nova I hurried to a college across the river, where the sports hall formed the venue for a Canon workshop run by Stephen Goldblatt, ASC, BSC, the man behind the lens for the likes of Lethal Weapon 2 and Batman Forever. The blurb for this workshop described Goldblatt as “a master of low light shooting”, and it was certainly pitch black when I walked in a few minutes late, and gingerly picked my way around to the far side of the hall to find a seat.

Lighting through lace

On a purpose-built bedroom set, Goldblatt was recreating lighting from the Robert Redford / Jane Fonda romantic drama Our Souls at Night, shot on the Sony F55 and Canon C300 Mark II. To practical lamps on either side of the bed he added egg-crated tungsten soft-boxes to beef up each one. He simulated moonlight through an imagined off-camera window by placing a lace curtain in front of a blue-gelled lamp and blowing it gently with a fan. An additional egg-crated soft-box provided a low level of blue toplight.

As he worked, Goldblatt revealed how he doesn’t miss ceulloid, loving how relatively easy it is now to light night exteriors or moving car scenes. “But just because you don’t need much light,” he cautioned, “it doesn’t mean you don’t want to control it.” Other developments coming down the pipe do not inspire him so much; he feels that high resolutions and HDR are unnecessary, pushed by marketing people rather than creatives.

He placed great emphasis on the importance of the eyes. “A common failing of newer DPs is that they worry more about the set than the eyes,” he said, before explaining how he will often walk beside the handheld camera with a torch, providing eye-light. He also stressed the importance of eye-lines. Although in any one shot it’s not that important how wide or tight the eye-line is, or how high or low, across the two hours of a feature film the decisions have a cumulative effect.

Trying out a Xeen lens in the exhibition hall

Goldblatt no longer uses a light meter. “Trust your eye, develop your eye,” he advised, adding that you must have a strong voice to remain in control of the images through postproduction.

After grabbing lunch, I returned to the Opera Nova to browse the exhibition hall. This closely resembled a mini BSC Expo or Media Production Show, with all the major camera and lens manufacturers displaying their wares, along with several lighting companies. I had a play with some of the cameras, including the actual Alexa 65 used on Rogue One.

Then I met up with Chris Bouchard, one of The Little Mermaid‘s two directors, who had arrived in Poland the previous day. We sauntered over to another venue, the MCK Orzeł, an independent cinema with a nice, chilled, film-buff-friendly atmosphere. The auditorium itself was packed though as we settled in for a seminar on “The Future of Digital Formats”.

 

Red Seminar: The Future of Digital Formats

Promoting Red’s Monstro sensor, the session was mostly about the benefits of shooting in high resolutions, and giving yourself the maximum flexibility in post. You can read my thoughts on both of those topics in upcoming Red Shark articles.

One of the speakers, Christopher Probst, ASC (DP of Mindhunter and technical editor of American Cinematographer magazine) made some interesting points about ISO. “Traditionally, low ISOs were used for bright scenes like day exteriors, and high ISOs were used for darker scenes like night exteriors,” he explained. “That was based on reducing the grain, getting the cleanest possible image on film.” He advised the opposite for digital capture. “Use a low ISO for nights to get more shadow detail, and a high ISO for days to get more highlight detail [in the sky, for example].”

“Independence Day: Resurgence” – DP: Markus Forderer, BVK

Another interesting nugget came from Markus Förderer, BVK. On Independence Day: Resurgence he switched between spherical, 1.3x anamorphic and 2x anamorphic lenses depending on the situation. For example, flatter lenses were better for wide shots – where anamorphics would distort straight lines – and for VFX work.

 

Hawk Vantage Seminar: Top cinematographers tell their Hawk stories

I ducked out of the Red session early so that I could pop back to the Opera Nova for the Hawk Vantage seminar, bumping into my Perplexed Music gaffer Sam Meyer on the way. Hawk were launching three new sets of lenses: MiniHawk (T1.7 hybrid anamorphics), Hawk Class-X (T2.2 2x anamorphics) and Hawk65 (T2.2).

A Hawk T1 in the exhibition hall

The MiniHawks in particular seem very exciting. Daniel Pearl, ASC showed us some stunning frame grabs from the upcoming Dennis Quaid vehicle Motivated Seller, shot using these lenses on Alexa Mini. Whilst having key advantages of spherical lenses (speed, small size, low weight, extremely close focus) the MiniHawks have a unique and beautiful cigar-shaped bokeh.

While Pearl had used the latest Hawks, Magdalena Górka, PSC had shot with some old ones, the C series, for Brad Silberling’s drama An Ordinary Man. “I had to frame everything centrally because that’s the only place that was sharp!” she laughed. Also addressing focus fall-off, Andrzej Bartkowiak, ASC (Speed, The Devil’s Advocate) stated, “I like anamorphic because the shallow depth of field allows you to direct the viewer’s eye more.”

Stuart Dryburgh, ASC (The Secret Life of Walter Mitty, Bridget Jones’s Diary) talked about shooting 1.3x anamorphic. He has done this on three-perf 35mm (to achieve a Scope aspect ratio), on an Alexa in 16:9 mode (again for 2.39:1) and on an Alexa in 4:3 mode (to get 1.85:1). He also recommended shooting on Super-16 with 1.3x glass, citing the example of Ed Sheeran’s “Thinking Out Loud” video, which Pearl shot.

Peter Flinckenberg, FCK (Upswing, Concrete Night) noted that, with the shift to digital acquisition, the DP is no longer a magician, “but you can bring back that magic with lighting and glass that has character.”

 

CW Sonderoptic: Exploring Large format cinematography & Leica lenses

I took my leave, dashing back to the MCK Orzeł for another lens-themed seminar, this time by CWSonderoptic, the makers of Leica. The first half of this panel revolved around a short film shot by Darius Khondji, ASC, AFC (Seven, Delicatessen) on an Alexa 65 with the new Leica Thalias.

The second half was all about Tod Campbell, DP of Stranger Things and Mr. Robot, focusing on the latter show. The second season of Mr. Robot was shot on Leica Summicrons after Campbell found that the Cookes used on season one distorted the many straight lines which became such a key part of the show’s unique look. “I look at season two as kind of the birth of the photography for the show,” he said. With a laugh he added: “Sorry that the lighting looks like shit in season one. I was learning!” (See my spherical lens tests for my own thoughts on Cookes and Leicas.)

One of my favourite shots from “Mr. Robot”

Campbell revealed that season three of Mr. Robot has a different look again, using much more camera movement and “twice as much atmos”. For this season he paired Canon K35 glass with an 8K camera, but due to the Canons’ low resolution he employed Leica Summiluxes for the wide shots.

He also shared some interesting information about his testing process, admitting that he doesn’t really know how other DPs test. He doesn’t use charts, he just makes it up. He always includes a candle, a practical lamp, some kind of highlight in the background, and random foreground objects (as background bokeh can differ from foreground bokeh).

 

Christopher Doyle Seminar

When the Leica seminar ended I went back to the Opera Nova, where Chris and I had dinner at the nice (and once again cheap – are you detecting a theme?) restaurant. Despite having got up at 4am (3am local time) I wasn’t feeling too tired, so we headed upstairs to the 10pm seminar by Christopher Doyle, HKSC (Hero, Lady in the Water). Many people were nursing beers, including Doyle himself, and the lecture theatre was dimly illuminated by mood lighting. Clearly this session was not going to be like the daytime ones.

“We’re going to fuck things up,” Doyle began, dispelling all doubts. He proceeded to talk disjointedly but entertainingly about his work on The White Girl and what I think was a separate film about a camera obscura. His oratory was liberally sprinkled with great one-liners, a few of which I reproduce here for your edification:

  • There are only three people in filmmaking: the actor, the audience and the cinematographer in between them.
  • If actors don’t feel loved, the performance will not come across on camera.
  • Give the idea the image it deserves.
  • [Vittorio] Storaro [legendary DP of Apocalypse Now amongst others] can’t tell you how to do it. You have to find it for yourself.
  • People in space – that’s what cinematography’s about.
  • The location is very important. It gives the energy, it imposes the style.
  • The lens doesn’t matter; it’s what it shows that’s important.
  • You never sleep because you care too much – that’s what filmmaking is.
With Chris Bouchard in front of the Opera Nova

Doyle also picked up on a piece of dialogue from a clip he screened: “What is it?” / “I don’t know yet.” It was a great summation of finding the essence of a shot, he said.

Having had our fill of aphorisms, Chris Bouchard and I slipped out to get a drink. The Cheat, the pop-up bar across the road, was absolutely packed, and my early morning was finally catching up with me, so I called it a night. The highstreet of Bydgoszcz was quiet and chilly as I walked briskly to my hotel, curiously located down a service road behind the city’s football stadium, reflecting on all that I had learnt that day.

Tune in next week for tales from my second day at Camerimage.

The Cinematography of “Perplexed Music”

In June I was recommended by a mutual friend to shoot a short drama called Perplexed Music, inspired by the Elizabeth Barrett Browning sonnet of the same name. It’s a passion project from writer-director Mark McGann, with his brother Paul McGann (Doctor Who, Alien 3, Withnail & I) in the lead role of a man grieving for his deceased partner.

Paul and Mark pose with one of the supporting artists between takes.

Mark was keen from the outset to shoot on an Alexa, and I was quick to agree. Arri Rental very kindly gave us an amazing deal on an Alexa Classic and a set of Ultra Primes. As on Above the Clouds, we used a Blackmagic Micro Cinema Camera as a B-cam, capturing two specific angles that were impossible on the Alexa with our limited grip budget.

Throughout July, Mark and I had a very satisfying creative dialogue about the cinematic techniques we would use to tell the story of Paul’s character, The Man, who never speaks. I had been watching a lot of Mr. Robot, and was keen to use unusual compositions as that show does. The visual grammar that we ultimately developed eschewed The Rule of Thirds, either squeezing The Man right into the side of frame – at times when things are too much for him – or placing him dead centre for moments of clarity and acceptance, and for flashbacks to when his partner was alive.

The Blackmagic Micro Cinema Camera is mounted on a combo lighting stand to capture a high angle through a streetlamp.

While testing lenses at Arri Rental a few weeks prior to the shoot, I took the opportunity to shoot some frame-rate tests between 24 and 48fps. Since the film has so little dialogue, I figured there was nothing to stop us using a lot of slow motion if we wanted to. I didn’t want it to look like a music video though. I thought perhaps a very subtle over-cranking, creating languid blinks and slightly heavier movement, would add to the burden of The Man’s grief. Mark agreed as soon as he saw the tests, and we ended up shooting a number of set-ups at 28 and 30fps, plus 40fps for a pivotal sequence.

I also tested various ISO settings on the Alexa (click here for full details, stills and video from this test). Based on these, I decided to use ISO 1600 for the majority of the film, partly for the extra latitude in the highlights, and partly to add grittiness to The Man’s grief-stricken world, in the form of a little picture noise. When we started shooting the flashbacks, on the spur of the moment I decided to switch to ISO 400 for these. A few years back I shot the music video below on a Red Epic and, for reasons I forget, one set-up was done at a lower ISO than the rest. I remember the feeling this gave, when I saw the final edit, of everything suddenly being smooth and hyper-real. (You can just about it discern it through the Vimeo compression at 1:48.) I thought that would be a great feeling to give to the flashbacks.

1st AC Rupert Peddle and 2nd AC Ben Davies set up a lakeside close-up under a diffusion frame which will soften the light on Paul.

Much of Perplexed Music was day exterior, but a couple of sequences required lighting. In the opening café scene, I fired HMIs through two windows, but kept their light away from The Man, keying him with a practical to put him in his own little world. Meanwhile, a happy couple he’s watching are bathed in sunlight (sometimes real, sometimes not) warmed up with a quarter CTO, and bouncing beautifully off their table to give them a healthy glow.

For night interiors at The Man’s home, I was keen to rely on practicals as much as possible. Firstly there wasn’t much space in the little cottage, secondly I didn’t want the hassle of having to shift them around to keep them out of frame when we changed angle, and thirdly it just looks more natural. So aside from a tungsten bounce in a corner of the living room we knew would never be seen, I stuck to practical table lamps and exterior lighting.

I had planned to use direct HMI sources for moonlight through the windows, but my gaffer Sam suggested going softer so that we wouldn’t have hard shadows inside which would need filling. I saw that he was right, so we used a kino through one window and a 2.5K HMI bounced into poly through another (pictured at left).

Perplexed Music was shot over five days in Frome in Somerset and Rame in Cornwall. The latter provided us with a spectacular cliff-top and the isolated St. Michael’s Chapel on the peak of the headland. Here we employed the services of The Fly Company, who captured two dramatic, sweeping shots on their DJI Inspire 2 drone. We were all extremely impressed by what they were able to achieve, especially as it was done in very windy conditions, in between rain showers.

We completed the final set-ups of the schedule as the winds began gusting up to 60mph, and poor Paul could barely stand upright! I was certainly glad we picked the Alexa to shoot on, because anything lighter would probably have shaken during takes, if not blown over!

I had a fantastic time working with Mark and Paul, and the whole cast and crew. We were sad to part ways at the end of the week, and we all look forward to seeing the finished film soon. And at this point, dear reader, I ask for your help. Currently a Kickstarter campaign is underway for postproduction. It’s well over 50% funded at the time of writing, but every little helps in our quest to reach the finishing line. Rewards for backers include thank you video messages from Paul and Mark, and tickets to a private screening in December. Even if you can’t contribute, please consider sharing the page on social media. Thanks!

The Cinematography of “Perplexed Music”

“Barry Lyndon”: The Full Story of the Famous f/0.7 Lenses

After seeing Barry Lyndon (1975) on the big screen this week, I felt compelled to write a blog post about its cinematography. But what aspect of the cinematography? The painterly look? The many zooms? The use of natural light?

What I knew for certain is that I should definitely not write about the entirely candlelit scenes lensed on f/0.7 Nasa glass, because everyone knows that story. However, reading the vintage American Cinematographer article and some other material, I found the details surrounding this groundbreaking use of high-speed lenses so interesting that I decided to do it anyway.

 

The Vision

Barry Lyndon is the 18th century tale of a low-born Irishman who strives – through various misadventures, and ups and downs of fortune – to become a gentleman. The key visual influence of director Stanley Kubrick and DP John Alcott, BSC were the great painters of the story’s era, such as Vermeer.

Next week’s post will look at this painterly influence in Barry Lyndon more closely, but for now the important thing is the use of candlelight on those classical canvases, and Kubrick’s desire to replicate that look. According to lens expert Ed DiGuilio, who was tasked with adapting the f/0.7 glass for Lyndon, Kubrick “wanted to preserve the natural patina and feeling of these old castles at night as they actually were”.

Typically in movies, a candle in frame may motivate the lighting, but most of the illumination on the actors actually comes from an orange-gelled lamp just out of frame. Kubrick wasn’t interested in shooting Lyndon that way. He wanted all the light in those night interior scenes to genuinely come from the candles themselves.

 

The Problem

How much light does a candle shed? Conveniently, there is a unit of illumination called the foot-candle. One foot-candle is the amount of light received from a standard candle one foot away. Without going into the detail of what a “standard” candle is, it is enough for our purposes to say that the scene below has a key light of about three foot-candles…

… because there are three candles, about a foot away from the actor’s face. (The level of your key light, and consequently where you set your aperture, is almost always measured at your subject’s face, as that is usually the focus of the shot and the most important thing to get correctly exposed. This is why we DPs are always waving light meters in actors’ faces.)

If we look at an exposure table, such as this one, we can see that a three foot-candle key can be correctly exposed with an aperture of T1.4 and an EI (exposure index) of 800. Today that would be no problem, with many digital cameras having a native EI of 800, and the availability of fast lenses like Zeiss Master Primes and Super Speeds.

In the mid-seventies however, long before the advent of digital cameras, things were not so simple. Kubrick and Alcott had little choice but to shoot on Eastman Kodak 100T 5254. Those first three digits denote the film stock’s exposure index: 100. Alcott pushed the stock (brought the brightness up during processing) one stop, re-rating it to an EI of 200. But it still needed four times more light, or two stops more light than our modern-day Alexa or Red. (Check out my post on f-stops and T-stops if you’re getting lost.)

If we’re losing two stops on the EI, we need to gain two stops on the aperture to compensate. And two stops up from T1.4 is T0.7. You may notice that T0.7 isn’t on that table I linked to. This is because a lens with such a large relative aperture pretty much doesn’t exist.

Pretty much…

 

The Solution

Kubrick obsessively researched the problem. He eventually discovered that Nasa had commissioned Carl Zeiss to build ten Planar 50mm f/0.7 stills lenses in the sixties, which were used to take photos of the dark side of the moon. (I was unable to find out the T-stop of these lenses, but I’ll assume it was close enough to T0.7 for it to make little difference to my calculations above.) The developments leading to these lenses stretched back through Nazi military applications during WW2 all the way to the late Victorian era, when the double-Gauss cell at the core of the lenses was first invented.

Anyway, Kubrick promptly bought three of the Zeiss Planars. He liked to own equipment himself, rather than hire it in, and to this end he had also purchased at least one Mitchell BNC camera. As befits Kubrick’s perfectionism, these were perhaps the world’s most precisely engineered cameras, previously used for special effects work.

This is where Ed DiGuilio comes in: “[Kubrick] called one day to ask me if I thought I could fit a Zeiss lens he had procured… to his BNC.” It wasn’t simply a case of the f/0.7 glass having the wrong mount. The rear element was so large and needed to be so close to the film plane that DiGuilio had to extensively modify the camera, literally cutting parts out of it.

Once this was done, extensive testing ensued. The focus scale (distances marked on the barrel) had to be calibrated from scratch, and indeed the focus ring was re-engineered to allow the precision focusing that the lens’ tiny depth of field would require. Whereas the focus ring on a stills lens will turn about 90° to go from infinity to close focus, and the ring on a cine lens might turn 270°, the rings on these unique Planars now turned a whopping 720° – two whole revolutions!

50mm is a very useful lens length for close-ups, but Kubrick understandably wanted a wider option as well. Accordingly, DiGuilio located an adapter designed to adjust the throw of cinema projector lenses. Mounted onto one of the 50s, it gave an effective focal length of 36.5mm with only very minor light loss. A 24mm version was also tested, but Kubrick disliked the amount of distortion in its images, and rejected it.

 

The Execution

The colour brown and the trousers of Doug Milsone, Barry Lyndon‘s focus puller, cannot have been strangers to each other. Imagine trying to hold focus on this dolly-back at f/0.7!

By my calculations (which were difficult, because most depth of field tables/calculators don’t go to f/0.7!) an MCU on Kubrick’s 50mm Planar with the subject at 2.5m (8.2ft) and the iris wide open would have had a depth of field of about 43mm (1.7″). To get this same depth of field at f2.8, a popular working stop for cinematographers today, the subject would have to be just 1m (3.3ft) from the sensor plane, which would be a biggish close-up. And remember that focus monitors, peaking and Cine Tape did not exist in the seventies.

To give Milsone a fighting chance, a unique system of focus assist was developed. While the main camera shot an actor from the front, a CCTV camera captured them in profile. This profile image was piped to a monitor, over which a grid was placed. This grid was marked off with distances so that Milsone could see how much the actor had moved by, far more accurately than judging it by eye from beside the lens.

Another problem thrown up by the low-light cinematography was with the viewfinder. Interestingly, the Mitchell BNC was a non-reflex camera, meaning that it didn’t have a mirror on the shutter, reflecting the image to the viewfinder when the shutter was closed. Instead, the camera body racked over to one side to allow the viewfinder to get an image during line-ups and rehearsals, and when it was actually rolling the operator got their images from a side viewfinder with its own lens – just like in a disposable 35mm stills camera. The original prism-based viewfinder on Kubrick’s Mitchell BNC suffered from far too much light loss for a candlelit image to be visible through it, so it was replaced with a mirror-based viewfinder adapted from a Technicolor camera.

The shots resulting from all of these technical challenges are quite soft to the modern eye, but I think that only adds to their beauty. Barry Lyndon captured the exquisite fragility of candelight, and 42 years on the images are still unique and captivating.
