Spherical Lens Tests

neiloseman, , , , , , , , , , , , ,

The other week I spent a day at Arri Rental in Uxbridge, in the Bafta Room no less, conducting various camera and lens tests. I’ve done a number a productions now where I wanted to test but there wasn’t the time or money, so for a while I’ve been meaning to go into Arri on my own time and do some general tests for my education and edification. An upcoming short provided the catalyst for me to get around to it at last.

Aided by 1st AC Rupert Peddle and 2nd AC Bex Clives, I tested a dozen lenses, some spherical, some anamorphic. Today I will cover the spherical lenses; next time I’ll look at the anamorphics.

 

Method

We shot on an Alexa XT Plus in log C ProRes 4444 XQ at 3.2K. In the video the image has been downscaled to 1080P and a standard Rec.709 LUT has been added.

I set the Alexa to ISO 800 and lit Bex to a T2.8 using a 650W tungsten fresnel bounced off poly. For fill I caught a little of the spill from the fresnel with a matte silver bounce board on the opposite side of camera. I placed fairy lights in the background to observe the bokeh (out of focus areas) and turned on a 100W globe during each take to see what the flare did.

We shot all the lenses at 2.8 – the stop I most commonly use – and also wide open (compensating with the shutter angle), but the direct 2.8 comparison proved most useful, so that’s mainly what you’ll see in the video. We tested a single length: 35mm or the closest available to it.

What we didn’t do was shoot grey-scale or colour charts, or do any testing of vignettes or distortion. (The day after doing these tests, Shane Hurlbut, ASC published an Inner Circle post about how to tests lenses, so I immediately learnt what my omissions were!)

We tested the following lenses:

Leica Summilux-C 29mm T1.4 18″ 1.7kg £27K
Arri/Zeiss Master Prime 35mm T1.3 14″ 2.2kg £16K

Skin tones

Click the image to see it at best quality.

The Arri/Zeiss Master Prime and the two Leicas seem to have the most vibrant skin tones. To my eye, the Leicas have a slight creaminess that’s very pleasing. The Canon looks just a little cooler and less dynamic. I was surprised to find that the Cooke S4, the lens I’ve used most, appears to have a grey, flat skin tone compared with the Master Prime, Leicas and Canon. I would rank the Ultra Prime and Superspeed next, on a par except that the Ultra Prime has a noticeable magenta cast. My least favourite skin tones are on the Zeiss T2.1, which comparatively makes poor Bex look a little bit ill!

Some of the nuances will be lost in the YouTube and Jpeg compression, but this is a very subjective assessment anyway, so feel free to completely disagree with all of the above. Any of the differences noted above could be corrected by grading, to some extent . But remember that the lens is at the very start of the light’s journey from set to screen, and any wavelengths that don’t get through it are lost forever. It’s like fluorescent lamps with colours missing from the spectrum; you can’t put those back in in post.

 

Sharpness

I have to say, I’m unable to detect any difference in sharpness between the Master Prime, Cooke S4, Canon and Leicas. The Ultra Prime and Superspeed both look a hair softer, while the T2.1 is very soft.

 

Breathing

Breathing is the slight zooming effect that you get with some lenses when you pull focus. Looking at 4:44 in the video you can clearly see the differences in breathing between the eight lenses. Because this part of the video is showing a crop of the bottom left corner of the image, the breathing manifests as a shift to the left (zoom in) as the lens is racked closer (goes soft) and a shift to the right (zoom out) as it’s racked deeper (goes sharp).

All the Zeiss lenses except the Master Prime have a significant amount of breath when seen in isolation like this, but not enough to be noticeable to an audience in most real-world situations. The Cooke S4 has a little bit of breathe, and the Canon a hair less. The Master Prime and the Leicas are rock solid.

 

Bokeh

Small points of light, when thrown out of focus, most clearly demonstrate the bokeh pattern of a lens. The shape of the bokeh is determined by the number of iris blades and the shape of those blades. Generally a circle is preferred, because it’s a natural shape, but for certain stories a more unusual shape might be appropriate. The shape of the iris changes with the T-stop, hence the T2.8 and wide open images above.

Immediately noticeable is the difference in the Cooke S4’s bokeh between wide open (circular) and T2.8 (octagonal). All of the other lenses have round bokeh at T2.8, apart from the Superspeed, which has heptagonal (seven-sided) bokeh.

It’s entirely subjective which bokeh you prefer. The only other thing I’ll point out is that the Canon’s bokeh wide open is very fuzzy, with noticeable colour aberration, though this may be due to the bright highlight rather than the defocusing.

 

Flare

Flare patterns also vary with aperture. The smaller the aperture, the more of a star effect you will get, as the light interacts with the corners in the iris blades. The Summilux shows this most clearly, with a pronounced star at T2.8 (two stops down from its maximum aperture) and almost none when wide open. The Cooke S4 also has a nice star pattern at T2.8. With the other lenses it’s much more subtle, and the Canon has almost none.

 

Conclusions

The real revelations in these tests, for me, were the Leicas. The Summilux in particular is a beautiful lens, with rich, dynamic skin tones, nice bokeh, no breathing, plus the bonus of nice star flares. I will definitely be looking to work with this glass in the future, although given the price tag that may be optimistic!

The Summicron also performed incredibly well, matching the more expensive Summilux and Master Prime in every respect except speed. I can see this becoming my new go-to lens.

The Master Prime of course produced a beautiful, sharp, clean image, but it lacks character. It might work nicely for science fiction, a drama requiring a neutral look, or something where filtration was being used to give the image character.

The Canon impressed me too – no mean feat given that it’s the cheapest lens we tested. With nice skin tones and attractive flares, I could see this working well for a romantic movie.

The Zeiss T2.1 did not appeal to me, with poor sharpness and cold, washed-out skin tones, so I would avoid it.

The Superspeed is a decent lens, but in most cases I’d plump for an Ultra Prime instead. Ultra Primes are certainly easier to work with for the 1st AC, and have proven to be a good workhorse lens for drama. (I shot Above the Clouds on them.)

The Cooke S4 has been my go-to glass up to now, and while it will probably remain my first choice for period pieces, due to its gentle focus fall-off, I’m excited to try some of the other glass in this test on other productions.

I’ll say it one last time: this is all subjective. Our visual preferences are what make every director of photography unique.

Tune in next week when I’ll look at the anamorphic lenses: Hawk-V, Cooke Xtal and Kowa Mirrorscope.

Spherical Lens Tests

Alexa ProRes ISO Tests

neiloseman, , , , , , , ,
My Cousin Rachel

I’ve shot three features on Arri Alexas, but I’ve never moved the ISO away from its native setting of 800 for fear of noise and general image degradation. Recently I read an article about the cinematography of My Cousin Rachel, in which DP Mike Eley mentioned shooting the night scenes at ISO 1600. I deliberately set off for the cinema in order to analyse the image quality of this ISO on the big screen. Undoubtedly I’ve unwittingly seen many things that were shot on an Alexa at ISO 1600 over the past few years, but this was the first time I’d given it any real thought.

To my eye, My Cousin Rachel looked great. So when I was at Arri Rental the other week testing some lenses, I decided to shoot a quick ISO test to see exactly what would happen when I moved away from the native 800.

But before we get to the test footage, for those of you unsure exactly what ISO is, here’s an introduction. The more experienced amongst you may wish to skip down to the video and analysis.

 

What is ISO?

A revised and updated version of this section is available.

ISO is a measure of a camera’s light sensitivity; the higher the ISO, the less light it requires to expose an image.

The acronym actually stands for International Organization for Standardization [sic], the body which in 1974 combined the old ASA (American Standards Association) units of film speed with the German DIN standard. That’s why you’ll often hear the terms ISO and ASA used interchangeably. On some cameras, like the Alexa, you’ll see it called EI (Exposure Index) in the menus.

A common ISO to shoot at today is 800. One way of defining ISO 800 is that it’s the sensitivity required to correctly expose a key-light of 3 foot-candles with a lens of T-stop 1.4 and a 180° shutter at 24fps, as we saw in my Barry Lyndon blog.

If we double the ISO we double the effective sensitivity of the camera, or halve the amount of light it requires. So at ISO 1600 we would only need 1.5 foot-candles of light (all the other settings being the same), and at ISO 3200 we would need just 0.75 foot-candles. Conversely, at ISO 400 we would need 6 foot-candles, or 12 at ISO 200. Check out this exposure chart if it’s still unclear.

ISO is one of the three corners of the Exposure Triangle, well-known to stills photographers the world over. You can read my posts on the other two corners: Understanding Shutter Angles and F-stops, T-stops and Optical Density.

Just as altering the shutter angle (exposure time) has the side effect of changing the amount of motion blur, and altering the aperture affects the depth of field, so ISO has its own side effect: noise. Increase the ISO and you increase the electronic noise in the picture.

This is because turning the ISO up causes the camera to electronically boost the signals it’s receiving from the sensor. It’s exactly the same as turning up the volume on an amplifier; you hear more hiss because the noise floor is being boosted along with the signal itself.

I remember the days of Mini-DV cameras, which instead of ISO had gain; my Canon XL1 had gain settings of -3dB, +6dB and +12dB. It was the exact same thing, just with a different name. What the XL1 called 0dB of gain was what today we call the native ISO. It’s the ISO at which the camera is designed to give the best images.

 

ISO and Dynamic Range

The Alexa has a dynamic range of 14 stops. That means it can simultaneously record detail in an area of brightness x and an area of brightness x times 2 to the power 14. At its native ISO of 800, those 14 stops of dynamic range are equally distributed above and below “correct” exposure (known as middle grey), so you can overexpose by up to 7 stops, and underexpose by up to 7 stops, without losing detail.

If you increase the ISO, those limits of under- and overexposure still apply, but they’re effectively shifted around middle grey, as the graphic to the left illustrates. (The Pro Video Coalition post this graphic comes from is a great read if you want more detail.) You will see the effects of this shifting of dynamic range very clearly in the test video and images below.

In principle, shooting at ISO 1600 is the same as shooting at ISO 800, underexposing by a stop (giving you more highlight detail) and then bringing it back up a stop in post. The boosting of the signal in that case would come right at the end of the image path instead of near the beginning, so the results would never be identical, but they’d be close. If you were on a bigger project with a DIT, you could create a LUT to bring the exposure up a stop which again would achieve much the same thing.

All of the above assumes you’re shooting log ProRes. If you’re shooting Raw then everything is simply recorded at the native ISO and any other ISO you select is merely metadata. But again, assuming you exposed for that other ISO (in terms of iris, shutter and ND filters), you will effectively get that same dynamic range shift, just further along the pipeline.

If this all got a bit too technical for you, don’t worry. Just remember:

Doubling the ISO

  • increases overall exposure by one stop,
  • gives you one more stop of detail in the highlights,
  • gives you one less stop of detail in the shadows, and
  • increases picture noise.

Halving the ISO

  • decreases overall exposure by one stop,
  • gives you one less stop of detail in the highlights,
  • gives you one more stop of detail in the shadows, and
  • decreases picture noise.

 

The Test

I lit the subject, Rupert “Are You Ready?” Peddle, with a 650W tungsten fresnel bounced off poly, and placed a 40W candle globe and some LED fairy lights in the background to show highlight clipping. We shot the tests in ProRes 4444 XQ on an Alexa XT Plus with a 32mm Cooke S4, altering the shutter angle to compensate for the changing ISOs. At ISO 400 the shutter angle was maxed out, so we opened the lens a stop for ISO 200.

We tested five settings, the ones corresponding to a series of stops (i.e. doublings or halvings of sensitivity): 200, 400, 800, 1600 and 3200. I have presented the tests in the video both as recorded in the original log C, and with a standard Rec.709 LUT.

You’ll need to watch the video at full-screen at 1080P to have any chance of seeing the differences, and even then you might see the compression artefacts caused by the noise more than the noise itself. Check out the stills below for a clearer picture of what’s going on. (Click on them for full resolution.)

 

Analysis

To me, the most important thing with every test is how skin tones are rendered. Looking at the original ProRes of these comparisons I think I see a little more life and vibrance in the skin tones at lower ISOs, but it’s extremely subtle. More noticeable is a magenta shift at the lower ISOs versus a green shift at higher ones. The contrast also increases with the ISO, as you can see most clearly in the log images.

At the lower ISOs you are not really aware of any noise in the picture. It’s only at ISO 1600 that it becomes noticeable, but I have to say that I really liked this level of noise; it gives the image a texture reminiscent of film grain. At ISO 3200 the noise is quite significant, and would probably be unacceptable to many people.

The really interesting thing for me was the shifting of the dynamic range. In the above comparison image, look at the globe in log – see how it starts off as one big white blob at ISO 200 and becomes more detailed as the ISO rises? Now look at the dark wall around the globe, both here and in the previous image – see how it subtly and smoothly graduates into darkness at the lower ISOs, but becomes a grainy mess at the higher ones?

I can see an immediate benefit to shooting at ISO 1600 in scenes lit predominantly with practicals. Such scenes tend to have a low overall level of illumination, while the practicals themselves often blow out on camera. Going to ISO 1600 would give me extra exposure and extra detail in the practicals. I would be sacrificing shadow detail, so I would have to be a little more careful not to underexpose any faces or other important elements of the frame, but I can deal with that. In fact, I often find myself determining my exposure in these types of scenes by how blown out the practicals are, wishing I could open up a little more to see the faces better but not wanting to turn the lamps into big white blobs. Increasing the ISO would be the perfect solution, so I’m very glad I did this test to alleviate my ungrounded fears.

What about scenarios in which a lower-than-native ISO would be useful? Perhaps a scene outside a building with an open door, where the dark interior is visible in the background and more detail is required in it. Or maybe one of those night scenes which in reality would be pitch black but for movie purposes have a low level of ambient light with no highlights.

I hope you’ve found this test as useful and interesting as I have. Watch this space or subscribe to my YouTube Channel for the lens test.

Thanks to Rupert Peddle, awesome steadicam op and focus puller – check out his site at pedhead.net – for appearing in front of the lens. Thanks also to Bex Clives, who was busy wrangling data from the lens tests while we were shooting these ISO tests, and of course Arri Rental UK.

“Above the Clouds”: Summer 2017 Pick-ups

neiloseman, , , , , , , ,

This time last year, principal photography had just wrapped on Above the Clouds, a comedy road movie directed by Leon Chambers. We always knew that there would be additional photography, and several days of this have been scattered over the past year.

In May I spent a few odd days with Leon and the Yellow Peril, primarily capturing car-to-car tracking shots. Leon had already shot some of these without me up in Cumbria, so he had the technique down. He attached his Blackmagic Micro Cinema Camera to his roof rack with clamps and suction cups – three points of contact in all, to eliminate vibrations.

The focus was left fixed at the approximate distance the cars would be apart, and I could reach out of the passenger window and tweak it, along with the variable ND filter, if necessary. Recording was triggered from the custom remote which Leon had made for the camera last year when we used it for the autumn pick-ups. I monitored on a 5″ Blackmagic Video Assist which – thanks to a firmware update – now has a false colour display, which was very useful for keeping an eye on the exposure.

We had no means of panning or tilting the camera during takes, so we would frame the car centrally, allowing the maximum space to each side for when we went around the bends. This had the nice effect of making the Peril look small in the landscape, surrounded by it on all sides.

And speaking of the Peril looking small, it had shrunk considerably when I next saw it. But so had the landscape.

To keep the audience informed of the characters’ progress across Great Britain, Leon planned to cut to a map at a few strategic moments. At some point the original plan of shooting an Ordnance Survey map on a wall turned into something much more elaborate, a work of art featuring found objects, such as the lead character Charlie might have made herself.

Leon knew he wanted to use his jib to drift the camera over the map. But what camera? We both agreed that these shots needed to have a noticeably different look to the rest of the movie. Both Super-8 and Super-16 were discussed, but ultimately neither were viable. Then I suggested shooting on a full-frame DSLR to get a tiny depth of field. I imagined the camera having fixed focus as it skimmed over the map, with features coming in and out of focus as they passed through the field. We didn’t end up doing that, but Leon did like the DSLR idea.

Asahi Pentax-M 50mm/f1.4

So the decision was made to shoot on a Canon 5D Mk III belonging to focus puller Max Quinton. We ended up shooting everything on a single lens, my Asahi Pentax-M 50mm/f1.4. This is a vintage K-mount stills lens which is beautifully sharp, and we mounted it with a passive EF adapter. 50mm on full-frame is equivalent to 35mm on Super 35, very close to the 32mm which was our most used lens length during principal photography.

I added a half Soft FX filter as I usually do. I had briefly considered omitting it, to further differentiate the map shots from the rest of the film, but undiffused shots in a mostly diffused movie draw attention to the filtration and can be quite jarring.

I offered Leon two options for the lighting. One was to simulate the natural light you would see if shooting the British Isles from a high altitude, i.e. a hard sun source and ambient toplight. The other, which he went for, was to carry on the suggestion of Charlie making the map herself, and make it look like she had lit it herself too, with an eclectic mix of practicals around the edge. A couple of tungsten Chinese lanterns were hung overhead as well for soft fill. To help the camera’s limited dynamic range, I put tough-spun diffuser inside some of the practicals’ shades, on the camera side.

The Blackmagic 5″ Video Assist can be seen here mounted on the back of the camera.

There were a couple of “night” scenes on the shot list. For these we turned off the Chinese lanterns and turned on a desk-lamp practical with a blue-ish LED bulb to suggest moonlight. We also used a string of LED fairy lights to represent a road with streetlights.

For the smallest possible depth of field, everything was shot at f1.4. Even at ISO 320, in the daylight scenes it was necessary to add a 0.45 ND filter to bring the exposure down to f1.4.  We shot on a neutral picture profile, piping the images via HDMI to the Blackmagic Video Assist, where they were recorded in ProRes 422 HQ.

After a few years shooting on Blackmagics, FS7s and Alexas, the 5D’s colour saturation and contrast seemed very pronounced to me, but that really suited the toy-like nature of the map. And the tiny depth of field made everything look even smaller and cuter than it already was.

So, that’s a wrap on Above the Clouds finally and forever. Apparently.

8 Ways “Barry Lyndon” Emulates Paintings

neiloseman, , , , , , , , , , , , , ,

Stanley Kubrick’s 1975 period epic Barry Lyndon, although indifferently received upon its original release, is considered a masterpiece by many today. This is largely due to its painterly photography with strong, precisely composed frames that leave the viewer feeling more like they’ve wandered through an art gallery than watched a movie. Today I’m going to look at eight methods that Kubrick and his team used to create this feel. It’s an excellent example of how a director with a strong vision can use the many aspects of filmmaking to realise that vision.

 

1. Storytelling

The American Cinematographer article on Barry Lyndon notes that “Kubrick has taken a basically talky novel and magically transformed it into an intensely visual film.” You have only to look at a series of frame-grabs from the movie to see just how much of the story is contained in the images. Just like a painter, Kubrick reveals a wealth of narrative within a single frame. The shot above, for example, while recalling the landscapes of artists like Constable in its background and composition, also clearly tells the story of a courtship threatened by a third party with violent designs.

 

2. Design

Kubrick was keen for Lyndon to feature the type of rich fabrics which are often seen in 18th century art. He referred costume designer Milena Canonero to various painters of the period. “Stanley wanted beautiful materials,” she recalls in the documentary Stanley Kubrick: A Life in Pictures, “because as he quite rightly said, that’s why in those paintings they gave that wonderful light.”

 

3. Aspect ratio

There was much confusion and controversy surrounding Kubrick’s intended ratio for Lyndon. The negative was apparently hard-masked to 1.6:1, with the result that VHS and DVDs used this ratio, while the images were vertically cropped to 1.78:1 for the later Blu-ray release. However, the discovery in 2011 of a letter from Kubrick to cinema projectionists finally proved that 1.66:1 was the ratio he wanted audiences to see the film in.

1.66:1 was a standard ratio in parts of Europe, but unusual in the UK and USA. It’s not far off the golden ratio (1.6180:1) – a mathematically significant ratio which some artists believe to be aesthetically pleasing. There is evidence that Kubrick was not a fan of wide aspect ratios in general, perhaps because of his background as a photographer, but it can be no coincidence that Lyndon distances itself from the cinematic ratios of 1.85 and 2.39, and instead takes a shape closer to that of a typical painting.

(Most of the images in this post come from Evan Richards’ Cinematographers Index, and he in turn grabbed them from the 1.78:1 Blu-ray. The image above is in 1.66:1 but shows the 1.78:1 crop-lines.)

 

4. Composition

“The actual compositions of our setups were very authentic to the drawings of the period,” says DP John Alcott, BSC in his interview with American Cinematographer. Perhaps the film’s most obvious compositional nod to classical art is the large amount of headroom seen in the wide shots. As this article by Art Adams explains, the concept of placing the subject’s head at the top of the frame is fairly new in the history of image creation. Plenty of traditional art includes lots of headroom, and Lyndon does the same.

 

5. Camera movement

There is little camera movement in Barry Lyndon, but there are 36 zoom shots. Unlike a physical dolly move, in which the parallax effect causes different planes of the image to shrink or enlarge at differing rates, a zoom merely magnifies or reduces the whole image as a single element. This of course only serves to enhance the impression of a two-dimensional piece of art. In fact, the zooms resemble nothing so much as the rostrum camera moves a documentary filmmaker might make across a painting – what today we’d call a Ken Burns effect.

It’s interesting to note that, although Barry Lyndon is famous for its fast lenses – the f/0.7 Zeiss Planar primes – the movie also used a very slow lens, a custom-built T9 24-480mm zoom. From various accounts, other zooms used seem to include a Cooke T3.1 20-100mm and possibly a 25-250mm of some description. Of course, none of the zoom lenses were anywhere near fast enough for the candlelit scenes, so in those instances the filmmakers were forced to use a Planar and pull back physically on a dolly.

 

6. Lighting

“In preparation for Barry Lyndon we studied the lighting effects achieved in the paintings of the Dutch masters,” Alcott says. “In most instances we were trying to create the feeling of natural light within the houses, mostly stately homes, that we used as shooting locations.”  The DP closely observed how natural light would come in through the windows and emulate that using diffused mini-brutes outside. This made it possible to shoot long days during the British winter when natural light was in short supply. Last week I covered in detail the technical innovations which allowed Alcott and Kubrick to shoot night scenes with just genuine candlelight, as 18th century painters would have seen and depicted them.

 

7. Contrast

Film stock in the seventies was quite contrasty, so Alcott employed a few methods to adjust his images to a tonal range more in keeping with 18th century paintings. He used a Tiffen No. 3 Low Contrast Filter at all times, with an additional brown net for the wedding scene “where I wanted to control the highlights on the faces a bit more,” he explains. He also used graduated ND filters (as in the above frame) both outdoors and indoors, if one side of the room was too bright. Most interestingly, he even went so far as to cover white fireplaces and doorways with fine black nets – not on the lens but on the objects themselves.

 

8. Blocking

The blocking in Barry Lyndon is often static. While this is certainly a creative decision by Kubrick, again recalling painted canvases and their frozen figures, it was also technically necessary in the candlelit scenes. Whenever the f/0.7 lenses were in use, the cast were apparently instructed to move as little as possible, to prevent them going out of focus. As one YouTube commenter points out, the stillness imposed by these lenses mirrors the stillness required of a painter’s model.

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

neiloseman, , , , , , , , , , ,

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.

9 Uses for Central Framing

neiloseman, , ,

A couple of weeks ago I wrote a post on lead room, the amount of horizontal space the subject is given in front of them in the frame. Commonly the subject is placed to one side or the other, but there can be times when sitting that actor bang in the middle of the screen is most appropriate and effective. Here are some reasons you might want to do it.

 

1. To show immersion in the environment

When you surround a character with equal amounts of the background on both sides, you embed them into that background, creating a strong connection between them and their environment. This can be seen to great effect in the above frames from Road to Perdition and Butch Cassidy and the Sundance Kid (DP: Conrad Hall, ASC) and The Revenant (DP: Emmanuel Lubezki, ASC, AMC).

 

2. To create power

Central framing can give a subject tremendous power and dominance, particularly in combination with a low angle, as seen in the above examples from House of Cards (DP: David M. Dunlap) and Django Unchained (DP: Robert Richardson, ASC).

 

3. To suggest formality or rigidity

These scenes from American Beauty (DP: Conrad Hall, ASC) use central framing to emphasise the formality of Lester’s performance review, and the stilted, suffocating nature of his home life.

 

4. To create order

Kubrick used central framing with strong single-point perspective to create worlds of perfect order… so perfect that they would have to come crashing down sooner or later. The above examples are from Full Metal Jacket (DP: Douglas Milsome, BSC, ASC) and 2001: A Space Odyssey (DP: Geoffrey Unsworth, OBE, BSC).

This shot from The Matrix (DP: Bill Pope, ASC) also uses central framing to symbolise order, the calculatingly perfect order of the machines.

 

5. To suggest duality

When you shoot a shot-reverse with both parties centred, the two characters appear to replace each other on screen every time you cut. This can suggest a strong connection between the characters, or a strong conflict as they battle for the same piece of screen. Donnie Darko (DP: Steven B. Poster, ASC, ICG) uses this technique to set up the antagonism of the rabbit, while also suggesting he’s a part of Donnie, a figment of his imagination.

 

6. For humour

Centre framing is of course a huge part of Wes Anderson’s style, as in The Life Aquatic with Steve Zissou and The Grand Budapest Hotel (DP: Robert Yeoman, ASC). But I don’t think it’s stylisation for stylisation’s sake; his movies all have the feeling of tall tales told by ageing relatives with the aid of a scrapbook full of dorky, posed photos. The symmetry helps create the dorkiness, and from thence – as Lee & Herring used to say – the humour arises. The same is true of this classic scene from Garden State (DP: Lawrence Sher, ASC).

 

7. For faster cutting

Mad Max: Fury Road (DP: John Seale, ACS, ASC) was framed centrally in service of the editing. Director George Hill realised that if he put everyone in the same place in frame, the audience wouldn’t need to search the screen for the subject after every cut, allowing him to edit faster without making the action incomprehensible. See this post for more on the cinematography of Fury Road.

 

8. For impact

When used judiciously, central framing can have a big impact, giving a character their moment in the spotlight, putting them centre stage. It can underline a key character or story beat. The examples above are from Hugo (DP: Robert Richardson, ASC), Rogue One (DP: Greig Fraser, ACS, ASC) and American Beauty again.

 

9. To Break the fourth wall

And finally, if your subject is looking into the lens, addressing the audience, then central framing is the natural composition. It’s not the only composition though; often the subject will be framed to one side so we can see the action continuing in the background even as it is narrated to us. But if the shot is just about the narrator, often central framing will be the most effective, as in the above shots from Amélie (DP: Bruno Delbonnel, AFC, ASC) and A Series of Unfortunate Events (DP: Bernard Couture).

9 Uses for Central Framing

The 2:1 Aspect Ratio

neiloseman, , , ,

Last autumn I wrote a post about aspect ratio, covering the three main ratios in use today: 16:9, 1.85:1 and 2.39:1. The post briefly mentioned a few non-standard ratios, including 2:1. Since then, I’ve noticed this ratio popping up all over the place. Could it be on its way to becoming a standard?

Today I’ll give you a little background on this ratio, followed by a gallery of frame grabs from 2:1 productions. The aim is simply to raise awareness of this new(ish) tool in the aspect ratio toolkit. As ever, it’s up to the director and DP to decide whether their particular project is right for this, or any other, ratio. However, I would caution low-budget filmmakers against picking what is still not a common ratio without considering that smaller distribution companies may crop your work to a more standard ratio either because of convenience or negligence.

Woody Allen and Vittorio Storaro shooting Café Society

Vittorio Storaro, ASC, AIC – the highly-regarded cinematographer of Last Tango in Paris and Apocalypse Now amongst many others – began championing the 2:1 ratio around the turn of the millennium. It was one of the most complicated times in the history of aspect ratios. The horror of pan-and-scan (butchering a movie to fit its 1.85:1 or 2.39:1 ratio into 4:3 without bars) was starting to recede with the introduction of DVD, which was in fact still 4:3 but could contain squeezed 16:9 content. Widescreen television sets were starting to build in popularity, but some programmes and films were being broadcast in the middle-ground ratio of 14:9 so as not to offend the majority of viewers who still had 4:3 sets. And Storaro recognised that HD would soon supplant celluloid as the primary capture and exhibition method for cinema, likely bringing with it fresh aspect ratio nightmares.

Storaro proposed “Univisium”, a 2:1 aspect ratio that fell between the two cinema standards of 1.85:1 and 2.39:1. It was a compromise, designed to make everyone’s life easier, to produce images that would need only minor letterboxing no matter where or how they were screened. However, the industry did not share his vision, and until recently 2:1 productions were relatively rare, most of them lensed by Storaro himself, such as Frank Herbert’s Dune, Exorcist: The Beginning and Storaro’s first digital picture, Café Society.

John Schwartzman shooting Jurassic World

Perhaps the biggest 2:1 movie to date is Jurassic World. DP John Schwartzman, ASC wanted to shoot anamorphic 2.39:1, while Steven Spielberg, exec producing, advocated 1.85:1 (like his original Jurassic Park) to provide more height for the dinosaurs. 2:1 was arrived at, again, as a compromise.

And compromise is likely what has driven the recent explosion in 2:1 material – not in the cinema, but online. Recent shows produced in this ratio include The Crown, A Series of Unfortunate Events, Stranger Things and House of Cards on Netflix, and Transparent on Amazon. I expect the producers of these series were looking to give their audience a more cinematic experience without putting off those who dislike big black bars on their screen, not unlike the reasoning behind the 14:9 broadcasts in the noughties.

2:1 may be a ratio born out of compromise, but then so was 16:9 (invented by SMPTE in the early eighties as a halfway house between 2.35:1 and  4:3). It certainly doesn’t mean that shooting in 2:1 isn’t a valid creative choice. Perhaps its most interesting attribute is its lack of baggage; 16:9 is sometimes seen as “the TV ratio” and 2.39:1 as “the big movie ratio”, but 2:1 has no such associations. One day perhaps it may be thought of as “the streaming ratio”, but for now it is simply something other.

Anyway, enough of the history and theory. Here are some examples of the cinematography that can be achieved in 2:1.

The 2:1 Aspect Ratio

Lead Room, Nose Room or Looking Space

neiloseman, , , ,

Like headroom, last week’s topic, lead room is one of the first concepts we are introduced to when we begin learning camera operation. And like headroom, it’s a rule that’s made to be broken. If a character is looking screen-left, certainly it’s most common to place them on the right of frame – giving them lead room (a.k.a. nose room or looking space) on the left, but that is not the only option. In certain situations it’s more appropriate, or simply more aesthetically pleasing, to place them on the left, or in the centre. And although The Rule of Thirds suggests how far to the left or right they will commonly be placed (a third, or two-thirds of the way across the frame) it is, again, far from the only option.

Below I’ve compiled a spectrum of lead room: a series of examples showing the whole range of horizontal positions within a frame where a subject could be placed. (Note: I’ve flopped some of the images to maintain the screen direction.) All of these examples are from 1.78:1 or 1.85:1 productions, but of course with the 2.39:1 Cinemascope format there is an even greater range of options. On the righthand side, to aid comparison, I’ve placed different crops of the same photo (by Richard Unger).

No composition is fixed in motion picture production. Actors move around, miss their marks; it’s difficult for a DP to be precise about where the subject appears in the shot, so reading a particular intention into an individual frame is dangerous. But if, within a film, there is a trend of characters, or a specific character, being placed in one particular part of the frame, then it’s fair to assume that the filmmakers were deliberately trying to create a particular effect.

With that in mind, the thoughts below are not intended to analyse why that specific shot in that specific production was composed the way it was, but rather to consider in general terms what meanings and emotions that kind of composition might convey.

 

“Carol” (DP: Edward Lachman)

This is the maximum lead room you can give an actor in 1.85:1 without cutting off part of their head (which you may want to do in certain extreme circumstances, but that’s a subject for another post). This is someone backed into a corner, isolated. They have full cognisance of their situation – they can see it all in front of them. What you choose to place on the other side of frame is very important with an extreme composition like this. Negative space, as in the above example, creates an unbalanced frame, suggesting someone in a precarious situation, whereas another person or object would appear to dominate the subject.

 

“Atonement” (DP: Seamus McGarvey)

This is widely considered to be the ideal framing, with the subject placed according to The Rule of Thirds. Assuming that Keira is looking at another actor here, and that that actor’s single is framed with him in the left half of frame, the brain can comfortably merge the two shots into one, creating – subconsciously – a split-screen like a phone conversation in an old sitcom. The shot-reverse will be pleasingly balanced, and no tension will be created – at least not by the lead room.

 

“Fargo” (DP: Roger Deakins)

On more than one occasion I’ve tried to frame a shot like this, only to be told by the director that the subject is “too close to the centre”, it’s “wrong” and the subject must be placed on a third. What I should have done is shown them this frame, said, “If it’s good enough for Roger Deakins….” and then coughed in a way that sounded suspiciously like “thirteen Oscar nominations”. What’s interesting about this composition is the visual tension it creates when edited with the reverse. If the other actor is similarly close to the centre, their images start to overlap, almost like they’re duking it out, and if the other actor is placed further from the centre, they will seem trapped by their interlocutor. Or maybe composing the shot this way sometimes just allows for the best range of movement from the actor and the most pleasing frame.

 

“Lost in Translation” (DP: Lance Acord)

Placing someone in the centre of frame can be very powerful. It suggests someone in control, balanced, dominant. Now of course, that is not at all an accurate description of Bill Murray’s character in Lost in Translation. But notice that big, bright practical light so close to his head; it completely unbalances the composition. This just goes to show that the subject’s   position relative to background elements can be of equal or greater importance to their position within the frame. I aim to do a whole post about centre-framing in the near future.

 

“Hugo” (DP: Robert Richardson)

Although short-sided, the boy still has some lead room, in fact an amount of lead room that would be perfectly normal in a 4:3 composition. Personally, I would be comfortable with this composition for purely aesthetic reasons, but it could also be used to create some visual tension, suggesting things unknown behind the subject, waiting to creep up on them figuratively or literally. It could also suggest the character is weak, particularly if intercut with another character who is more traditionally framed.

 

“Les Miserables” (DP: Danny Cohen)

Now we are into territory that many will find uncomfortable. A character short-sided like this may seem unbalanced, lost, trapped, wrong-footed or isolated. Or they might simply be deep in thought;  you can easily imagine another character entering in the background of the above frame, breaking Crowe’s reverie, restoring the compositional balance and turning it into a deep two-shot.

 

“Mr. Robot” (DP: Tod Campbell)

Imagine someone walking into a room and standing right up against the wall, facing it. You would think them strange, disturbed. You might wonder if they were looking at something imaginary. This is the effect created by extreme short-siding. It also serves to make the subject look completely alone, even though they might be speaking to someone just inches in front of them. Mr. Robot is the only place I’ve ever seen composition this unusual, though I’m sure there are other examples out there.

 

Next time you watch a film or a TV show, pay attention to the lead room. You may be surprised to find that non-standard compositions are employed more often than you thought.

Lead Room, Nose Room or Looking Space

Headroom

neiloseman, , , ,

One of the first things that amateur photographers and cinematographers are taught is  “correct” headroom. Don’t put people’s heads in the middle of the frame, we’re told, but at the top. Rules are made to be broken though, and here are three examples of beautiful cinematography which do just that.

 

Broadchurch

“A town wrapped in secrets” is the tag-line of this critically-acclaimed ITV detective serial. In classic murder mystery fashion, every character is hiding something, causing suspicion to rest on each of them for a little while until the the person hiding the right secret is found.

David Tennant’s DI Alec Hardy complains of the small coastal town’s “endless sky”, an observation which could equally apply to the cinematography, framing the action as it often does with expansive headroom. While this may be partly an attempt to emphasise the isolation of the titular town, where people are small in the face of nature, its primary effect is to evoke the secrecy so integral to the storyline. Just as the police – and viewers – are figuratively misdirected by the suspects’ lies, so the camera is literally misdirected. The message from Matt Gray, BSC’s cinematography is: look at the beautiful sky and the paintings high up on the wall, because if you look too hard at what’s in front of you, you’ll see that the surface perfection of the bucket-and-spade idyll is built on foundations of sand.

 

Utopia

This stylish, stunningly-photographed thriller ran for two seasons on Channel 4 in 2013 and 2014. It featured a group of disparate characters following clues in a cult graphic novel to uncover a chilling conspiracy. It was the first TV show I’d ever seen in 2.39:1, it had a garish, digitally-manipulated palette, and its composition broke all the rules.

Amongst Utopia‘s visual hallmarks was the use of plentiful headroom. Characters were frequently crushed into the lower half of the frame, a symbol of the powerful conspiracy looming over them. The overall look crafted by director Marc Munden and DP Ole Bratt Birkeland placed the viewer completely outside of the comfort zone of TV’s visual conventions, into a world where you couldn’t trust or rely on anything. (The Amazon series Mr. Robot uses similar techniques for similar reasons.)

Both seasons of Utopia can be viewed free at channel4.com

 

IDA

The makers of the Oscar-winning Polish indie feature Ida also chose an unusual aspect ratio; 4:3 had not been commonly used in features for decades. It was director Pawel Pawlikowski who wanted to try framing his subjects low down within the boxy ratio, leaving lots of headroom.

DP Lukasz Zal, PSC embraced the idea. “We saw that [the odd framing] created the feeling of loss, isolation and that it wasn’t just a strange mannerism but it conveyed so much more,” he told The LA Times.

Many interpretations have been placed on the meaning of the extra headroom in this tale of a young novitiate nun who comes to question her lifestyle. Most commonly it is seen as implying heaven above and therefore the nuns’ thoughts of the divine. To me it also conveys a sense of helplessness, of free will being overcome by larger forces above and around Ida.

Read this post on the ASC website for more on the cinematography of Ida.

If you want to delve deeper into the topic of headroom, I highly recommend this article by Art Adams: A Short History of Headroom, and How to Use It.

I’ll leave you with Pawel Pawlikowski’s thoughts on the ambiguity of his framing in Ida…

Some audiences have said the sky was crushing them. When you do something that’s formally strong, it elicits all kinds of responses. When you make these decisions, they’re kind of intuitive. You don’t intellectualize what it means; it feels right.

My 5 Favourite Cinematographer Commentaries

neiloseman, , , ,

I won my first DVD player in a trailer competition on a sort of YouTube forerunner site in December 2000. Over the next decade I was entertained and educated by many extras-packed Digital Versatile Discs. Now, of course, physical media is a thing of the past, but many of the anecdotes I heard in DVD commentaries have stuck in my mind. Some have even helped me on set when facing a new situation.

So, if you’ve got these discs on your shelf and never given the commentary a listen, or if you’re passing a CEX or Cash Convertor with a shiny new pound coin burning a hole in your pocket, you could do worse than seek out these classic chat tracks.

 

5. Moulin Rouge

DP Don McAlpine is actually quite quiet on this track, leaving director Baz Luhrmann and production designer Catherine Martin to do much of the work. This latter pair explain how sets, miniatures and CGI were blended to create the world of Moulin Rouge. At one point Luhrmann notes that he resisted the temptation to digitally stabilise the crane shots in the Elephant Love Medley, preferring to recall the look of classic 20th century musicals which did not have access to such postproduction trickery. A few nuggets we get from McAlpine include his use of blue light on Satine (Nicole Kidman) to make the most of her pale skin, the anachronistic use of follow spots for the stage shows, and how he was briefed by Luhrmann in one scene to light Jim Broadbent like the devil – which he did with flickering orange firelight from a low angle.

Highlight: Performing in what proves to be her final show, Satine wears a diamond necklace which reflects dazzling light onto Richard Roxburgh’s lustful duke. McAlpine reveals that he created the shimmering reflections by shaking some canvas with pieces of broken mirror on it.

 

4. X-Men 2

Although the DVD menu lists it as a director’s commentary, Bryan Singer in fact pairs up with his DP Newton Thomas Sigel for this track. Sigel discusses the importance of building practicals into the sets to enhance realism and flexibility of shooting. He explains how he colour-coded certain scenes so that the audience would more readily understand where they were during the fast-paced action sequences; for example, the corridors of the Alkali Lake bunker were lit with a moss green.

Highlight: The brutal claw-fight between Wolverine and Lady Deathstrike features dynamic and unusual camerawork. Sigel and Singer reveal that they used a cable rig to swoop the camera towards the duelling mutants, knowing that the camera would bounce back when it reached the end of its cable, but embracing this for the extra energy it added to the sequence.

 

3. Garden State

DP Lawrence Sher shares (no pun intended) a commentary track with director Zach Braff and production designer Judy Becker. The trio give an insight into the way that the moods and emotions of the film were enhanced by the colours, design, framing and camera movement. Braff and Sher chose a static look with strong compositions, punctuated by occasional Technocrane moves and at least one quasi-crane move that was actually captured on a Steadicam. Various happy (and unhappy) accidents helped shape the look too, like the constant rain throughout the exterior shoots, the mist and flaring practicals in the pool party scene, and the square of light on the airport wall behind Braff and Natalie Portman in the final shot.

Highlight: Sher explains the use of different film stocks to delineate threads of the story. Scenes with Large’s father (Ian Holm) were rendered cold and clinical by shooting on a sharper, harder Kodak film, while Portman’s sequences were imbued with organic warmth by Fuji stock. The feel was further enhanced by lighting and the colour choices in the respective sets.

 

2. Alien 3

The departure of director David Fincher from Alien 3 – under a cloud of studio interference and re-edits – is an infamous part of movie lore. Less well known is that the director of photography changed a week into shooting, after original DP Jordan Cronenworth (of Blade Runner fame) fell ill. Alex Thompson stepped in, and his humble, soft-spoken observations are spliced with other crew and cast members to form the commentary track on the Alien Quadrilogy boxset version of this film. Throughout the track he explains how he created the cool, toppy look of the prison’s communal areas, the dark, shadowy environs of the basements, and the hot, hellish feel of the lead-works. There are some interesting remarks about practicals too, such as the deliberate use of mismatched, low-CRI fluorescent tubes to give the canteen a run-down look, and tips for creating convincing firelight flicker.

Highlight: To create the illusion of glowing molten metal in the colony’s lead-works set, Thompson placed a veritable arsenal of lamps – almost 1,000 amps’ worth – underneath sheets of trace. Despite their brilliance, the individual units were still visible on camera, rather than a continuous white glow. According to Thompson, it was Fincher who came to the rescue, wiping grease from the side of his nose onto the lens to diffuse the offending lamps. I hope he let the AC put an optical flat on first!

 

1. Armageddon

Whatever you think of this slice of outer-space Bayhem, there’s no denying that DP John Schwartzman’s commentary on the Criterion Collection edition (spliced in with two of the film’s scientific advisors) is a fascinating insight into photographing the biggest of big-budget blockbusters. Schwartzman reveals that seven miles of cable were laid by his electrical department in preparation for extreme wide shots of the Armadillo vehicle travelling across the asteroid – in reality the South Dakota Badlands at night. Elsewhere he discusses lighting through coloured windows, shooting under UV lights (pictured above), dealing with spacesuit helmet reflections, and how Spielberg’s lens-meister Janusz Kaminski stepped in to shoot pick-ups of meteorites wiping out Shanghai.

Highlight: Schwartzman and his team photographed two real shuttle launches for the movie. Nasa decreed that the 35mm cameras had to sit in position on the launchpad, threaded with film and ready to go, for two days before take-off. The camera dept undertook extensive testing to making this possible, dealing with such problems as the condensation that would form as the temperature changed over the 48 hours. When they returned to the cameras after the launch and examined the one which had been the closest to the shuttle’s rocket motors, they discovered that the lens was in pieces, the vibrations having undone every single screw!
