Mixed colour temperatures in “Annabel Lee”

Colour temperature starts with something mysterious called a “black body”, a theoretical object which absorbs all frequencies of electromagnetic radiation and emits it according to Planck’s Law. Put simply, Planck’s Law states that as the temperature of such a body increases, the light which it emits moves toward the blue end of the spectrum. (Remember from chemistry lessons how the tip of the blue flame was the hottest part of the Bunsen Burner?)

Colour temperature is measured in kelvins, a scale of temperature that begins at absolute zero (-273°C), the coldest temperature physically possible in the universe. To convert centigrade to kelvin, simply add 273.

Tungsten bulbs emit an orange light - dim them down and it gets even more orangey.The surface of the sun has a temperature of 5,778K (5,505°C), so it emits a relatively blue light. The filament of a tungsten studio lamp reaches roughly 3,200K (2,927°C), providing more of an orange light. Connect that fixture to a dimmer and bring it down to 50% intensity and you might get a colour temperature of 2,950K, even more orange.

Incandescent lamps and the sun’s surface follow Planck’s Law fairly closely, but not all light sources rely on thermal radiation, and so their colour output is not dependent on temperature alone. This leads us to the concept of “correlated colour temperature”.

Colour temperature chartThe correlated colour temperature of a source is the temperature which a black body would have to be at in order to emit the same colour of light as that source. For example, the earth’s atmosphere isn’t 7,100K hot, but the light from a clear sky is as blue as a Planckian body glowing at that temperature would be. Therefore a clear blue sky has a correlated colour temperature (CCT) of 7,100K.

LED and fluorescent lights can have their colour cast at least partly defined by CCT, though since CCT is one-dimensional, measuring only the amount of blue versus red, it may give us an incomplete picture. The amounts of green and magenta which LEDs and fluorescents emit varies too, and some parts of the spectrum might be missing altogether, but that’s a whole other can of worms.

The human eye-brain system ignores most differences of colour temperature in daily life, accepting all but the most extreme examples as white light. In professional cinematography, we choose a white balance either to render colours as our eyes perceive them or for creative effect.

6000K HMI lighting photographed at 3200K to give a moonlight feel to “Heretiks”

Most cameras today have a number of white balance presets, such as tungsten, sunny day and cloudy day, and the options to dial in a numerical colour temperature directly or to tell the camera that what it’s currently looking at (typically a white sheet of paper) is indeed white. These work by applying or reducing gain to the red or blue channels of the electronic image.

Interestingly, this means that all cameras have a “native” white balance, a white balance setting at which the least total gain is applied to the colour channels. Arri quotes 5,600K for the Alexa, and indeed the silicon in all digital sensors is inherently less sensitive to blue light than red, making large amounts of blue gain necessary under tungsten lighting. In an extreme scenario – shooting dark, saturated blues in tungsten mode, for example – this might result in objectionable picture noise, but the vast majority of the time it isn’t an issue.

Left: daylight white balance preset (5,600K). Right: tungsten white balance preset (3,200K)
Left: daylight white balance preset (5,600K). Right: tungsten white balance preset (3,200K)

The difficulty with white balance is mixed lighting. A typical example is a person standing in a room with a window on one side of them and a tungsten lamp on the other. Set your camera’s white balance to daylight (perhaps 5,600K) and the window side of their face looks correct, but the other side looks orange. Change the white balance to tungsten (3,200K) and you will correct that side of the subject’s face, but the daylight side will now look blue.

Throughout much of the history of colour cinematography, this sort of thing was considered to be an error. To correct it, you would add CTB (colour temperature blue) gel to the tungsten lamp or perhaps even place CTO (colour temperature orange) gel over the window. Nowadays, of course, we have bi-colour and RGB LED fixtures whose colour temperature can be instantly changed, but more importantly there has been a shift in taste. We’re no longer tied to making all light look white.

A practical light of the “wrong” colour temperatures in “Finding Hope”

To give just one example, Suzie Lavelle, award-winning DP of Normal People, almost always shoots at 4,300K, halfway between typical tungsten and daylight temperatures. She allows her practical lamps to look warm and cozy, while daylight sources come out as a contrasting blue.

It is important to understand colour temperature as a DP, so that you can plan your lighting set-ups and know what colours will be obtained from different sources. However, the choice of white balance is ultimately a creative one, perhaps made at the monitor, dialling through the kelvins to see what you like, or even changed completely in post-production.

The Cinematography of “Alder”

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

Back in February 2019 I spent a long day in Black Park, a forest behind Pinewood Studio, shooting a short film called Alder for director Vanda Ladeira. A little late perhaps, but here are my reflections on the cinematography and general experience of making this experimental fairytale.

The film is about a forager (Odne Stenseth) who does not realise he is being watched by the very spirit of the forest, the titular Alder (Libby Welsh). As he cuts a sprig of holly, or steps on a mushroom, he is unknowingly causing her pain. Meanwhile a group of ghosts – Alder’s former victims? – cavort in the woodland, and strips of film made with ground-up human bone reach out from the trees to ensnare the forager.

Vanda contacted me after seeing my work on Ren: The Girl with the Mark. She was keen for Alder’s lair to have the same feel as Karn’s house in that series. We had a number of meetings to discuss the tone, visuals and the logistics of the shoot, which initially was going to take place over two days but was eventually compressed to one.

In October 2018 we conducted a recce in a forest that we ultimately weren’t able to use. I remember at the time that I was considering shooting the project on celluloid, tying in with the plot point about Alder making film from her victims’ bones. I dropped the idea after taking light readings on that recce – when it was very overcast – and realising just how dark it could be under the tree canopy.

We ultimately shot on a Blackmagic Ursa Mini and Xeen primes, provided along with the lighting kit by gaffer Jeremy Dawson. The Blackmagic sensors seem to do very well with earthy tones, as I noticed on the village set of Ren, and the Ursa rendered the browns of the bracken, the soil and the forager’s costume nicely. Jeremy also provided us with a jib which enabled us to underscore the forager’s action with some definite moves: an introductory crane down; a dramatic pull up as he drives his knife into a tree; and a frantic boom down with him as he searches for his lost compass. In Alder’s lair we kept the camera drifting from side to side or up and down to bring energy to her more static scenes.

Lighting for the forager’s scenes was all natural, with just a little bounce or negative fill from time to time to keep some shape to the image. An Artem smoke gun, operated by Claire Finn, was used on almost every shot to give the forest some life and mystery, and also to keep the backgrounds from getting too busy; the grey wall of smoke serves to fade the background slightly, keeping the eye focused on the foreground action.

As there was no dialogue, I was free to change the frame rate expressively. Examples include: over-cranking close-ups of the forager’s feet and hands in contact with nature, emphasing the sensuality of his unwitting connection to Alder; over-cranking the dance of the ghosts to make their movements even more beautiful and supernatural; and under-cranking the forager slightly to enhance his panic when he finds himself lost and surrounded.

Alder’s lair was a set built by Denisa Dumitrescu in the forest. I took broadly the same approach to lighting it as I had for the reference scene from Ren, making some holes in the branch-covered roof and shining a blinder (a bank of four LED spotlights) through it to produce dappled shafts of sunlight. On the floor around Alder were a number of candles; we beefed up the light from these by skipping an 800W tungsten lamp off a bounce board on the floor.

The biggest challenge was the meeting between the two main characters, a scene scripted for daylight which we were forced to shoot after dark due to running behind schedule. It was the longest and most important scene in the film and suddenly the cinematography had to be completely improvised. We did not have anywhere near the lighting package that a woodland night exterior normally calls for – just 800W tungsten lamps, a few LED fixtures, and a generator only powerful enough to run one of each.

What I ended up doing was putting an 800 in the background, ostensibly as a setting sun, and bouncing a blinder off poly-board as fill. We shot the whole scene through in a single handheld shot, once with smoke and once without, then picked up a few close-ups.I tried to hide the lack of light in the background by allowing the 800 to flare the lens and render the smoke almost impenetrable at times. Vanda and her editor, Tom Chandler, leant into the strange, stylised look and bravely intercut the smoky and smokeless takes. The result is much more magical and expressive than what we would have shot if we had still had daylight.

You can watch the finished film here. It won me Best Cinematographer at the New York Cinematography Awards (August 2019) and Film Craft Award: Cinematography at Play Short International Film Awards (2019).

Today filming begins on the Shakespearian feature I have been prepping since early February. All of last week was again spent in rehearsals, this time focusing on the second half of the script.

By the end of the week I had storyboarded almost the entire film, using Artemis Pro. The production designer was able to print these out and go through them looking for any backgrounds that he might not yet have dressed, or any obtrusive existing objects that should be removed. The 1st AD was also using them to help him plan, as he had not been present at rehearsals. This led to a minor panic when I erroneously included some characters in the background of a shot that those actors were not scheduled for!

Aside from producing these storyboards and getting a fantastic understanding of how all the scenes are going to be played and blocked, a big benefit of the rehearsal weeks was the opportunity to get to know the cast. Normally I have to wave a big camera in an actor’s face the first time I meet them. It’s much better to ease them and me into the process the way we’ve done on this production. A particular highlight was when the well-known lead actor performed some of the famous soliloquies – in the absence of a camera – right into my eyes.

It was a very busy week for all concerned. When the cast weren’t in rehearsals they were in costume fittings or make-up tests, or training for the sword-fight, or doing press interviews.

The gaffer started work on Wednesday, and was joined by the best boy and spark on Thursday. After loading in the equipment, their first task was to re-globe all the sconces and ceiling lights in the auditorium. Later they gelled all the emergency lights to make them dimmer and warmer in colour, ran distro to various convenient points, and cut poly-boards to size.

The camera kit also turned up on Thursday, a slightly surreal event for me after so long working in the building with just my laptop and iPhone. For a few scenes Sean wants to create a kaleidoscopic effect, so I had purchased some cheap kaleidoscope party glasses, a 6” teaching prism, and a set of crystals which can be hung off the matte box. Ironically the cheap glasses give the best effect! These will be hand-bashed in front of the lens, whereas the prism can be clamped to a noga arm for a more controlled effect.

I gave the focus puller a tour of the building so that he could start to think about monitor positions. That will definitely be a tricky aspect of the production with all the cramped backstage spaces.

I feel better-prepared now than I have ever felt going into a feature. It is such a contrast to, say, Heretiks, where I had just one week to get up to speed, and the gaffer had no prep time whatsoever. Nonetheless, there are some things you just can’t work out until the day, and that’s where the stress and excitement come from!

I’ll continue to write a blog during production, but I won’t be publishing it until the film is released. So there will be no new posts for the next few weeks, but normal service will resume in May! See you on the other side.

By the time you read this I will have entered the Covid bubble for the still-as-yet-unannounced Shakespearian film, the beginning of two weeks of full time prep before cameras finally roll.

The week just gone has been something of a calm before the storm. It started with two important Zoom meetings: one about practicals, the other about the schedule.

The first meeting involved going through all the locations with the production designer explaining what practical lamps he planned to put in each, and me sometimes asking for additional ones. Practicals are going to be a big part of our lighting, and this sort of collaboration with the art department can make a real difference between a smoothly-running shoot and a world of pain wherever you’re trying to hide film lights because you don’t have enough practical sources.

The second meeting, coming shortly after I saw the shooting schedule for the first time, was an in-depth discussion of it with the director, producer, line producer and 1st AD. Most of my concerns – other than some days which felt uncomfortably heavy, and even one or two that seemed wastefully light – were around times of day and equipment. For example, one daylight interior scene was scheduled for the end of day, when we might be losing the light. (The next day I went through it all again by myself and made sure that any night scenes scheduled for daytime could be reasonably done with blacked-out windows.)

We also talked a lot about how things could be rejigged to get as much value as possible out of the two days that we have the crane. It’s expensive, and no-one wants it sitting around while we shoot little dialogue scenes in tiny rooms. Nor do I want one or two scenes in the film to have lots of crane shots and the rest to have none; a sprinkling of them throughout the film would be preferable, though it would mean lots of costume and make-up changes.

Another draft of the script was issued , with pretty minor changes, though one extra room has been introduced, so that will need a proper recce next time I’m there. Reading through a new draft and updating my notes takes the best part of a day, and though it can sometimes feel like a chore, every reading helps me understand the story and characters better.

I did a little more shot-listing later in the week, but it will be much better and easier to do this at the rehearsals over the next fortnight, when I can see how the actors are approaching their characters and how they’re going to use the spaces. I can even take Artemis photos if it doesn’t interrupt their process too much. Roll on rehearsals!

The main event of last week’s prep was a test at Panavision of the Arri Alexa XT, Red Gemini and Sony F55, along with Cooke Panchro, Cooke Varotal, Zeiss Superspeed and Angenieux glass. More on that below, along with footage.

The week started with Zoom meetings with the costume designer, the make-up artist, potential fight choeographers and a theatrical lighting designer. The latter is handling a number of scenes which take place on a stage, which is a new and exciting collaboration for me. I met with her at the location the next day, along with the gaffer and best boy. After discussing the stage scenes and what extra sources we might need – even as some of them were starting to be rigged – I left the lighting designer to it. The rest of us then toured the various rooms of the location, with the best boy making notes and lighting plans on his tablet as the gaffer and I discussed them. They also took measurements and worked out what distro they would need, delivering a lighting kit list to production the next day.

Meanwhile, at the request of the producer, I began a shot list, beginning with two logistically complex scenes. Despite all the recces so far, I’ve not thought about shots as much as you might think, except where they are specified in the script or where they jumped out at me when viewing the location. I expect that much of the shot planning will be done during the rehearsals, using Artemis Pro. That’s much better and easier than sitting at home trying to imagine things, but it’s useful for other departments to be able to see a shot list as early as possible.

So, the camera tests. I knew all along that I wanted to test multiple cameras and lenses to find the right ones for this project, a practice that is common on features but which, for one reason and another, I’ve never had a proper chance to do before. So I was very excited to spend Wednesday at Panavision, not far from my old stomping ground in Perivale, playing around with expensive equipment.

Specifically we had: an Arri Alexa – a camera I’m very familiar with, and my gut instinct for shooting this project on; a Sony F55 – which I was curious to test because it was used to shoot the beautiful Outlander series; and a Red Gemini – because I haven’t used a Red in years and I wanted to check I wasn’t missing out on something awesome.

For lenses we had: a set of Cooke Panchros – again a gut instinct (I’ve never used them, but from what I’ve read they seemed to fit); a set of Zeiss Superspeeds – selected after reviewing my 2017 test footage from Arri Rental; a couple of Cooke Varotal zooms, and the equivalents by the ever-reliable Angenieux. Other than the Angenieux we used on the B-camera for The Little Mermaid (which I don’t think we ever zoomed during a take), I’ve not used cinema zooms before, but I want the old-fashioned look for this project.

Here are the edited highlights from the tests…

You’ll notice that the Sony F55 disappears from the video quite early on. This is because, although I quite liked the camera on the day, as soon as I looked at the images side by side I could see that the Sony was significantly softer than the other two.

So it was down to the Alexa vs. the Gemini, and the Cookes vs. the Superspeeds. I spent most of Thursday and all of Friday morning playing with the footage in DaVinci Resolve, trying to decide between these two pairs of very close contenders. I tried various LUTs, did some rough grading (very badly, because I’m not a colourist), tested how far I could brighten the footage before it broke down, and examined flares and bokeh obsessively.

Ultimately I chose the Cooke Panchros because (a) they have a beautiful and very natural-looking flare pattern, (b) the bokeh has a slight glow to it which I like, (c) the bokeh remains a nice shape when stopped down, unlike the Superspeeds’, which goes a bit geometric, (d) they seem sharper than the Superspeeds at the edges of frame when wide open, and (e) more lengths are available.

As for the zoom lenses (not included in the video), the Cooke and the Angenieux were very similar indeed. I chose the former because it focuses a little closer and the bokeh again has that nice glow.

I came very close to picking the Gemini as my camera. I think you’d have to say, objectively, it produces a better image than the Alexa, heretical as that may sound. The colours seem more realistic (although we didn’t shoot a colour chart, which was a major oversight) and it grades extremely well. But…

I’m not making a documentary. I want a cinematic look, and while the Gemini is by no means un-cinematic, the Alexa was clearly engineered by people who loved the look of film and strove to recreate it. When comparing the footage with the Godfather and Fanny and Alexander screen-grabs that are the touchstone of the look I want to create, the Alexa was just a little bit closer. My familiarity and comfort level with the Alexa was a factor too, and the ACs felt the same way.

I’m very glad to have tested the Gemini though, and next time I’m called upon to shoot something great and deliver in 4K (not a requirement on this project) I will know exactly where to turn. A couple of interesting things I learnt about it are: (1) whichever resolution (and concomitant crop factor) you select, you can record a down-scaled 2K ProRes file, and this goes for the Helium too; (2) 4K gives the Super-35 field of view, whereas 5K shows more, resulting in some lenses vignetting at this resolution.

Prep for the yet-to-be-announced Shakespearian feature continued last week. Tuesday and Wednesday saw me on Zoom calls with the producers – discussing camera kit quotes – and the costume designer. “Will we see enough of his face through this headgear?” was a question for the latter. She in turn asked how white a white coat should be, and how dark surrounding characters should be to make one person in black stand out. Difficult things to quantify, but important.

The week’s main event was another two-day recce with the director and production designer. The designer had produced beautiful and detailed mood-boards for every room, and had even started to bring in the right furniture and test paint colours. The main aim of the recce was to discuss and sign off on his decisions so that decoration and dressing could step up to full steam.

As we moved from room to room, trying to keep in story order whenever possible, the director revealed lots of his thoughts about the tone and key beats of each scene. I was pleased to find that these were largely in a similar vein to notes I had amassed on my own spreadsheet. And when they weren’t in sync, that was very useful to know at this stage! For most scenes I showed him a reference image or two, again from my spreadsheet, to double-check that we were on the same page.

We were visited during the recce by a grip who had come to see whether a crane would fit into our main location, and if so what kind of crane and whether it could achieve the shots we wanted. I had envisaged using a Giraffe like the one we had on The Little Mermaid, but the grip suggested we would be much better off with a 23ft Technocrane and a basic remote head, as this can telescope and retract rather than only sweeping around in an arc. We measured the distances to see where the camera could end up, and then I used Artemis Pro – a director’s viewfinder app – to see what framing that would translate to with various lenses. One of our most important shots should just be possible at the full extent of the arm, combined with the full range of a 25-250mm zoom.

Whether the budget can afford the crane, however, is yet to be confirmed. This week I am due to conduct camera and lens tests, and once I’ve made a decision on those then we will know what is left for fancy grip equipment!

The only other thing to happen last week was the hiring of a data wrangler. Since I lined up the 1st and 2nd ACs quite soon after my own hiring, the camera department is now complete.

I continue to saturate myself in the script for the yet-to-be-announced Shakespearian film. Some other little projects I had going on have now wrapped up, leaving me free to concentrate purely on this production, which is due to start shooting a month from now.

I spent the best part of last Monday reading a new draft of the screenplay and updating my spreadsheet of notes to reflect the changes. Going back over this spreadsheet and the script and re-evaluating them from different angles formed a signficant part of the rest of the week. On Thursday, for example, I focused on the swordfight (narrows it down, Shakespeare fans!), scouring YouTube for reference videos and noting which camera angles seem most dangerous and engaging. In fact, watching references was another big part of the week. I worked my way through the whole Godfather trilogy (above), some more episodes of Servant, bits of several action movies that have a specific type of night exterior, and a couple of the lead actor’s recent films, to see how other DPs have lit and lensed him.

At the end of the week I went back over the spreadsheet and filled in at least one idea for every scene that did not yet have an entry in its “camera” or “lighting” column. Sometimes this would be an idea for a specific shot – e.g. “angle from outside the window looking in”; sometimes it would be a general vibe for the camerawork – e.g. “close, handheld, intimate”; sometimes a specific source – e.g. “soft top-light rigged to ladder”; sometimes a more general lighting note – e.g. “group in a patch of light, surroundings dark”.

Production sent over the quotes they have received for my camera list. At least one of them was within the budget, so that’s good! This week I’ll discuss that with the producers and hopefully decide which rental house we’re going with.

Speaking of equipment, a cheap novelty optical item arrived from eBay. I used this and my iPad to shoot a very rough demonstration of how we might achieve a special effect in camera, sending the video to the director for his feedback. He liked it, and wants to add in a few more instances of it throughout the film.

Another idea I proposed was a lighting effect, for which I sent the director this video I’d found online (below). I don’t intend to do something exactly like this in the film, but I saw a way it could be modified to our story. I ended up shooting my own rough test that is closer to how I see it working in our film.

Less exciting than any of the above, but very important, was taking an online Screenskills course in Covid awareness. I’d done the Basic Awareness course already, which takes about 30 minutes including a brief quiz, but Screenskills were offering free places for HoDs on a more in-depth course, so I signed up. This consisted of a three-hour presentation about the virus, how it can spread on set and what can be done to mitigate it in various departments, followed by another quiz. I learnt a few new things and my awareness was indeed raised.

Prep on the yet-to-be-announced Shakespearian feature continued last week. (Read the previous week’s post here.)

On Monday I went back to the location with the gaffer, someone I’ve worked with several times before, and looked at all the spaces we will be using. It is too early to start any lighting plans, but we talked in general terms about what sort of instruments we might want to use and roughly where. The gaffer had already seen my lighting mood board (above) and we had discussed the overall look on the journey to location, so we were already on the same page about what we are trying to achieve. He had some technical conversations with staff at the location about the existing lighting and power sources, and we finished the day by checking out one of the film’s few exteriors as it was getting dark, in order to see what existing sources there are for the night scene we will be shooting there.

I spent a significant chunk of Wednesday on a Zoom call with the production designer, and a couple of other crew, going through each of the spaces again and finding out what changes the art department are planning to make to them. It was great to see the designer’s reference images and to show him some new ones of my own so that we can bounce off each others’ ideas and keep the film on a coherent track. This is especially important as we intend to rely heavily on practical lights for many of the rooms. The location has some already in place, but we will be adding lots more.

The designer mentioned The Shining as a useful reference for the project. To my shame, I had never seen it, a mistake I swiftly corrected. I immediately saw that the designer was right, as the film’s setting of a single, large, empty location lit almost entirely by tungsten practicals in the public areas and fluorescents in the service areas has a lot in common with our intended look for this project.

I lost no time in passing the reference on to the gaffer, and to the director, who I spoke with on Friday. We discussed a number of general topics – approaches I think is the best word – and he updated me on some changes to the script.

I’ve been developing a large spreadsheet breaking the script down scene by scene, with basic info like location, time of day and a brief summary of the action, as well as notes on character, camera and lighting, and a couple of the most relevant reference images. This will get more detailed and specific as prep progresses.

Watching reference material is a big part of the process at the moment. As well as The Shining, I’ve recently checked out Alfonso Cuarón’s Roma, M. Night Shyamalan’s Servant, Ingmar Berman’s Fanny and Alexander, and I have Francis Ford Coppola’s Godfather trilogy on my list too. Shoot for the moon and you might land on the roof, right?

Finally, with the help of my 1st AC, I put a very rough camera list together. My hope is that soon I can conduct tests to make a final decision on camera and lenses.

“The Little Mermaid”: Prep Diary Part 2

neiloseman, , , , , , , , ,

This is the second part of my flashback to spring 2016 and the pre-production for The Little Mermaid. Part one is here.

 

Weeks 3 & 4

Nothing much seems to happen the third week of prep. After the Shirley shoot finishes on Monday, I take Tuesday off. I’m so exhausted I can barely move, which bodes ill for the 26-day slog of principal photography that’s coming up! Things are quiet in the office on Wednesday and Thursday, and Friday is Good Friday so it’s a holiday. The three-day weekend is enjoyable but also frustrating given how much prep there is still to do.

Next Monday I go scouting with Anthony, the new locations manager. He takes us to a quarry ten minutes down the road from the office, where we finally find the cliff we’ve been searching for since prep began. The location has a lot of potential for many scenes, so we’re very pleased. (Ultimately it went unused because of safety concerns.)

On Tuesday there’s a page turner, which is like a table read only without the cast. We spend five hours going through the script, asking questions and addressing issues that might come up. I try to clarify certain things in the script and make sure everyone knows how Chris, the director, wants to approach things. (He’s just a talking head on my iPad right now, due to visa delays.)

Gaffer Mike and key grip Jason have arrived in town for the page turner, and on Wednesday morning we get down to the business of writing a lighting list. It’s difficult for me to get my head around the crew structure here in the States. The gaffer is the head of the electrical department, so they only deal with lamps and distro. Flags, cutters, nets, black-out, bounce boards and so on are handled by the grip department, led of course by the key grip… who also handles the camera grip, like cranes and dollies.

Most of the rest of the week is spent visiting locations with Anthony, Mike and Jason, while the latter two finesse the list and get quotes. On Wednesday evening I convene the camera department to debrief from the Shirley shoot and discuss what can be done to improve the crew structure, equipment package and workflow.

By the weekend it stills feel like there is much to figure out, and there is only one week left before principal photography begins. Still, I won’t be sorry to say goodbye to office work and get back on set.

 

Week 5

It’s the last week of preproduction and we should be spending it doing tech scouts and production meetings. But unfortunately many HoDs have been hired late, and there are lots of locations left to find, so it’s a frustrating week for me, waiting for stuff to happen. I try to nail down the grip and electrical items which are only required on specific dates, but it looks like some of that will have to be done as we go along.

I spend more time location scouting with Anthony, during which I realise just how time-consuming it is to drive around, spot possible places, make friends with the owners and just get to the stage where any of the crew can check it out.

We visit a possible beach location, a nice little spot on the same island we did the Shirley Shoot on. Chris, still unable to enter the US, participates by video call. He wants me to roll up my trousers and test the water, because the principal cast will have to spend hours in it. It’s nice enough for a paddle, but I don’t think I’d want to spend a day up to my waist in it. (Actually, that’s exactly what I and several other cast and crew end up doing.)

As the week goes on I spend less and less time at the office, because there simply isn’t much left I can do. I occupy my evenings swimming in the pool and binge-watching season one of Outlander, which Starz have made free for a couple of weeks here in the US. The cinematography in the first couple of episodes is utterly stunning, in fact it’s the most beautiful cinematography I’ve ever seen. It’s very inspirational, and I have a couple of good ideas for lighting A Little Mermaid as I watch it. (Recently I had the exciting chance to ask David Higgs BSC about lighting the Outlander pilot, for an article in the January issue of British Cinematographer.)

Chris finally arrives on Saturday, two days before the shoot. In the evening there’s a “pre-game” party by the pool. It finally feels like we’re making a movie. The equipment has all arrived, and there are trucks and trailers parked outside the production office.

On Sunday we do the closest we’re going to get to a tech scout. It’s great to be able to walk around a location with the directors at last. (Writer Blake has joined Chris as a co-director.) I try to use Helios, a sun tracker app, to work out when the sun will hit the back of the house, but in the end I trust my own estimation better. I whip out my light meter to check the contrast ratio between sunlight and shade; it’s 8:1 (3 stops), well within the Alexa’s dynamic range, but setting up an ultrabounce to fill in the shadows, as the key grip suggests, will make the image much more pleasing to the eye.

I figure out the broad strokes of the lighting for the interiors and let the G&E (grip and electric) team know the plan. With Larry, the 1st AD, I discuss how we’re going to maximise our two cameras in order to make our day.

I can’t believe we’re about to start principal at last. Five weeks is by far the longest prep time I’ve ever had for a movie. It’s feels like I’ve been here forever! But I’m only halfway through my time in Savannah…

Here are links to my diary entries from the shoot:

The Little Mermaid is currently available on Netflix around the world.

I’ll soon be starting five weeks of prep for a feature, and it’s got me thinking about the five weeks I spent in the spring of 2016 prepping The Little Mermaid. I published a number of entries from my production diary when the film was released, but the entries from pre-production have gone unseen… until now…

 

JANuary 12th, 2016

It is four or five months since Chris, the director, first mentioned the project to me. In that time he has been developing the script with the writer and producers, and I’ve read a draft or two. Last week I was introduced to the producers by email, and today Chris and I get together to start chatting about the film.

It’s just broad strokes today, nothing structured, nothing firm. He talks me through the next round of script changes and we watch some bits of DVDs I’ve brought. I’m not thinking photographically yet, just tone and genre, so we watch parts of The Rocketeer and Big Fish. I start to get some basic ideas of what Chris does and doesn’t like.

Yesterday I went to the library to get my head around the geography of the state our story is set in, and bit of the history and culture. I found a book called Photographing America and it has some interesting plates from the Deep South in the 30s and 40s. They set the stage for me in terms of architecture, landscape and clothing, but their gritty black and white photography is not appropriate for this film.

Chris and I Skype Fabio, the line producer, and later have a brief conference call with producers Armando and Rob. At this stage it is just about introductions. Chris enthuses about me to them, and curates some stills from Ren: The Girl with the Mark to wow them with. Armando responds positively – it’s just the look he’s after for this. Well, this is the second feature job Ren’s got me. Cheers, Kate!

 

Week 1

Since that day in London with Chris, I’ve done bits and pieces of prep around finishing up post on Ren. The script went through a few more drafts, I joined in a few conference calls with members of the team, and started a shot list.

But on March 5th I fly into Savannah, Georgia and I’m straight into full-time prep, living and breathing A Little Mermaid.

On Sunday I wake early, my body still five hours ahead of US East Coast Time. After talking to Chris, who’s still in the UK due to visa delays, I take a ten-minute walk through the sunny streets of Savannah to meet David, the storyboard artist. We eat blueberry pancakes with maple syrup and he shows me his boards for the movie’s finale. Chris Skypes in and we discuss the priorities. We need about 15 more sequences boarded – at least key frames – ASAP so that production designer Jay can be sure to accommodate our needs in the sets he is already starting to build.

At noon I head over to an apartment complex where Jay and line producer Fabio are staying. This place has a pool so I’m getting myself moved here as soon as I can. We spend seven or eight hours, with Chris on Skype, going through the schedule line by line, making sure everything is doable and everything is in the most efficient order.

Poppy Drayton is playing our mermaid. Back at the apartment I watch a trailer for The Shannara Chronicles and screen-capture all her close-ups. I analyse the lighting in each one, labelling them accordingly in a folder. Her time on this production is limited so I probably won’t get to camera-test her; I need to figure out how to light her based on what other DPs have done.

Monday is my first day at the warehouse. It’s an old supermarket that’s been gutted. There are four or five small offices and then a huge open space, part of which is occupied by the bones of the “rocky pool” set.

The week soon settles into a blur of video calls with Chris, interviews with potential camera assistants and gaffers, and lots of discussions about sets and locations. It’s really exciting to be shown around the space by Jay as he describes all the sets he’s going to build. For some scenes there is a lot of back and forth about whether they should be studio or location. We are working with a child actress and Chris is very keen to get the best performances, so the level of control we could get in the studio is very appealing, but that must be balanced against our art department budget.

I’m assigned an office that’s just 6ft square but is very cool because it has a sort of camera obscura in the door so I can see a little projection of what’s outside. Of course the door doesn’t really close properly (particularly once I’ve run an extension cable in to compensate for the lack of functioning power sockets in the room) but never mind. By mid-week I have a monitor to hook my Mac Mini up to and I’m properly in business.

I task the PAs with printing out the script and taping it in a long line of pages along a wall along with the corresponding storyboards. Eventually we will add reference images and concept art, if I can ever get access to a functioning colour printer!

A little bit of location scouting takes place during the week. We check out a nice rustic field behind the studio where we’ll set up our circus, we visit a fort in the hope that it might work for a scene near the finale (it doesn’t) and I take a look around the beach house we’ll be shooting the film’s present-day book-ends in on March 20th and 21st. (Principal photography starts April 11th.)

Another issue to be decided is which camera to shoot on. Initially we discussed having lots of cameras, which meant going with Reds for budgetary reasons. The Panasonic Varicam is suggested, and I’m almost flown to Atlanta to test it, but in the end we decide to go with Alexas, thank God. (With hindsight, I really should have gone and tested that Varicam. I was irrationally against all non-Alexa cameras at this time.) We’ll have two bodies, one for me and one for a B camera operator who will sometimes splinter off into a 2nd unit. The glass will be Cooke S4s with a half Soft FX filter, the exact same recipe as Heretiks. I know this will give me the organic, period feel that A Little Mermaid needs, as well as the magical quality. We’ll also have a couple of Optimo zooms in the kit, a luxury we couldn’t afford on Heretiks.

By the end of the week I’ve pretty much locked down the camera kit, finished the shot list for the whole movie, and hired 1st and 2nd ACs and a 2nd Unit DP. We still don’t have a gaffer, which is worrying. The crew pool in Savannah is not huge and we’re struggling to find people with enough experience.

On Saturday, aside from a couple of hours in the studio, I chill out. I’ve now moved to the same apartment complex as the rest of the crew, and I’ve just had a very nice dip in the pool. I think I might just have the best job in the world.

 

Week 2

At the end of this week we have our two-day “pre-shoot” with Shirley MacLaine, to capture the contemporary bookends to what is otherwise a 1930s story. Peter Falk’s scenes in The Princess Bride are an inevitable reference for these.

Director Chris is still having visa issues, so writer Blake will be on helming duty for the pre-shoot. He gives me Maggie Smith’s storytelling scene in Hook as a reference. I haven’t seen the movie in ages, so I rent it and watch the whole thing, delighting in the beautiful cinematography. I love the candy blues and hot pinks of Wendy’s London home, and will aim to emulate them.

A lot of this week is taken up with locking down equipment and personnel for the pre-shoot. The biggest issue as the week opens is that I still don’t have a gaffer. With my options limited – and despite a brief panic during which flying my UK gaffer out here seems like a very real possibility – I pick someone on a trial basis. If they do a good job for the pre-shoot they’ll get hired for principal.

Because the gaffer is hired so late, putting together a lighting list is my responsibility. I hate doing this, because I always forget stuff and piss everyone off at the last minute by making additions or changes. Like forgetting to check whether the HMIs are pars or fresnels. (I always want fresnels because they produce better shafts of light.)

With equipment and crew in place, my attention turns towards principal for a little while. The VFX supervisor, Rich, has flown in from LA, and together we scout some locations. Unfortunately none of the locations are locked yet and the options we are given to look at are far from ideal. But we have a good session going through the shot list together, checking that there aren’t any VFX requirements that he missed in his breakdown.

We also discuss shooting format, which is generally going to be 2K ProRes 4444. He wants me to shoot green-screen shots in Arri Raw, but after he’s gone I realise that we don’t have the right Codex on our cameras for that. 3.2K ProRes will have to do. Another good tip Rich gave me is to expose the green-screen at key (i.e. the same light reading on the green-screen as on the talent’s face) or up to half a stop over.

I’m glad I invested in a light meter, which arrived at the studio this week. It also comes in handy during another scout of the pre-shoot location. We have some night shots on the beach, which will have to be shot at dusk because it’s too big an area to light artificially. During the scout I take light readings on the beach at dusk, and determine that we have until 7:50pm, 20 minutes after sunset, before it is too dark to shoot.

If you want to follow the chronology, my diary entries about the “pre-shoot” are here.

Tune in next week for my diary entries from the remaining three weeks of prep. The Little Mermaid is still on Netflix if you fancy checking it out.
