Lighting Droplets

The tarsier puppet in Droplets

Lighting in the controlled environment of a studio should theoretically be much easier than lighting a location, but I found recently that it doesn’t come without its challenges.

Last month I had the pleasure of working on a music promo for Droplets by Lewis Watson and Gabrielle Aplin. Directed by Tom Walsh and designed by First Musketeer veteran Amy Nicholson, this magical, handmade puppet fest was only the second or third studio-bound production of my career. Tom had secured the use of Giltbrook Studios, an impressively equipped 1,300 sq ft soundstage in Nottingham, complete with manager Andy Swain as gaffer.

Apart from the exclusion of pesky natural light, the biggest advantage offered by a stage over a location is the lighting grid; no more wondering if that polecat or K-clamp will take the paint off the wall, and no more compromising your backlight position to keep the stand out of frame. The downside of the grid is the time it takes to rig or adjust a light, particularly if the grid, like Giltbrook’s, has no catwalks, and every adjustment must be made by bringing in and scaling a huge ladder. In fact it may be impossible to rig or adjust lights once there is a finished set underneath. All of which means you’re going to need a pre-rig day.

Some of the ill-fated space lights can be seen here, as well as the cucoloris rigged beneath the 650W fresnel key light. At the top left is the 2K fresnel backlight.

In the case of Droplets, the pre-rig day was also used to assemble the set, a tree on top of a cave, which must have measured about fifteen feet in height. As soon as it had been erected we realised that the six space lights Andy had spent all morning rigging were going to be in frame, as the top of the tree reached above the bottoms of these lights. (A space light is a circular arrangement of six tungsten tubes inside a cylinder of white diffusion cloth. They’re typically used in large numbers to simulate daylight in a studio.)

In fact my options on where I could put lights were very narrow, because of the lack of space around the set, both vertically and horizontally. We shot against the studio’s white infinity cove, and Tom wanted colour washes over this to suggest various times of day. Andy achieved this with gelled par cans off to either side of the set, but then it was crucial that no other light spilled onto the backdrop or it would ruin the effect.

We rigged a 2K tungsten fresnel immediately behind and above the set, for backlight, but it was hard to put anything in from the sides or the front without contaminating the backdrop. The 650W key light had to be rigged almost directly above the set, and even then its shadow can be seen on the floor in the wide shots if you look carefully. We hung a cucoloris (sheet of wood with random shapes cut in it) below the 650 to created the dappled effect of woodland light, taking care that a patch of light fell on the tarsier puppet’s main position.

For fill I used an LED panel off to the right of the set, dimming it to find a balance between its light being barely visible on the backdrop while still lifting the set and the puppets enough. I placed a smaller LED panel inside the cave, with a turquoise gel to suggest phosphorescence.

The final day/sunset look. From each side an orange-gelled and a pink-gelled par can light the backdrop. A 2K tungsten fresnel provides backlight, while a 650W fresnel with a cucoloris provides dappled light on the tree and tarsier. An LED panel off right supplies fill, and a second panel is inside the cave with a turquoise gel.

Another advantage of a studio is that you can easily run all the lamps into a dimmer board. This was very handy for Droplets because in addition to the day/sunset look, we had nighttime scenes and a storm to light for, and some on-screen transitions between the states. We were able to set these all up in advance and switch between them pretty much by just pushing a few sliders up and a few others down.

The night state involved a yellow-gelled redhead on the floor behind the cave, pointed straight at the backdrop. With its barn doors removed, this created a circle of light which reminded me strongly of the huge yellow moon in the posters for The Nightmare Before Christmas. I hadn’t been intending to create such a defined circle, but when I saw it I immediately loved its stylised look.

A second 650W fresnel was rigged, close to the first, and with ulcered black wrap in front of it to again created a dappled look, but with a purple gel on it. This took us away from the more traditional blue of nighttime scenes, adding to the stylised look again, and contrasting nicely in colour with the yellow “moon”.

The 2K backlight remained on for the night scenes, but the sunset colour wash on the backdrop was switched off, as was the fill.

Nighttime in puppet land: the 2K backlight remains on, a yellow-gelled redhead lights the backdrop from behind the set, and a purple-gelled 650W fresnel in the grid pushes through a cucoloris to highlight the tarsier.

For the storm scene we experimented with strobes, but they caused unpleasant rolling shutter artefacts. Instead I used the flash button on the 2K’s dimmer box to create lightning. Both 650W fresnels were turned off for this state, but the fill was turned back on. While the pink colour wash remained off, we brought up the orange wash just a little bit to suggest an angry sky in the background.

Stormy weather. The orange colour wash coming from the par cans, originally set up for the sunset look, is used here much more dimly to suggest an angry sky. The LED panel off right supplies fill while the 2K backlight is flashed periodically.

Copious smoke was used throughout (another advantage of studios – your smoke stays put!) to generate god rays as the backlight streamed through the tree. It also helped soften the backdrop and render the colour washes more convincing as a sky.

Where to Put Your Key Light

What angle the key light hits a character at is a KEY (groan) decision for a director of photography. The lighting featurette in my last post looked at some of the options, but today I’d like to expand on those with some more up-to-date examples.

Imagine a clock face. You’re looking down on the scene and your talent is at the centre with their eyeline to twelve o’clock.

The key light clock

With that in mind, consider the following shots. The camera is at between twelve and one o’clock in each case.

Half past eleven

Eleven o'clock
Eleven o’clock
Quarter to eleven

Half past nine (Aimee Denaro in See Saw)
Half past nine (view the See Saw trailer)

Clearly the level of fill makes a big difference, but you can already see that a key light at noon gives a flawless, evenly lit look which is great for a leading lady, while a half-past-nine casts half of the face into darkness for a threatening or mysterious feel. There is a sweet spot I love at about quarter to eleven where, on one side of the face, only the eye and a triangle on the cheek are lit. But generally between half past ten and half past eleven models the face nicely.

In all of the above examples, with the camera at one-ish, the key was between nine and twelve, i.e. the key was on the opposite side of the eyeline to the camera. This is known as lighting the “downside” – the side away from camera. Most cinematographers, myself included, consider this the most pleasing side to light from, as it shows the shape of the face and gives a nice shadow area on the camera side into which you can dial your preferred amount of fill.

Here is an example of lighting the upside:

Key light at eleven o'clock, camera at eleven thirty (click here to link through to this interview with renowned designer Dick Powell, by Astute Graphics)
Key light at eleven o’clock, camera at eleven thirty (Click here to link through to this interview with renowned designer Dick Powell, by Astute Graphics)

In many scenes, the position of the keylight will be dictated by the layout of the set or location, so a DP should consider this in pre-production discussions with the production designer, on location scouts or when the director is blocking the actors.

Soul Searcher: 10 Minute Lighting Masterclass

Continuing the tenth anniversary releases of the Soul Searcher DVD extras, this week we have the 10 Minute Lighting Masterclass. It’s a quick guide to some of the basic set-ups and techniques used to give the film its cinematic, moody look. Since making this featurette digital cameras have improved vastly and so has my lighting, so these days I would light more subtly with fill and soft sources, but the basic building blocks in this video are still valid. Later in the week I’ll expand on some of those building blocks here on the blog.

Soul Searcher: 10 Minute Lighting Masterclass

Gaffering Basics

A director of photography should always be backed up by a good gaffer. They will ensure that all the lights are rigged safely and that the appropriate power supply is provided for each one. Here are some basics you need to know if you’re stepping into this role.

Redheads draw 800W each
Redheads draw 800W each

P=IV

Remember that from GCSE Physics? Power = current x voltage, or watts = amps x volts. From this we can calculate that an ordinary 13 amp domestic socket on the 240V UK mains supply can provide up to 3,120W.

A redhead draws 800W, so we can run three off one socket (3 x 800 = 2,400W which is under the 3,120W limit) without blowing a fuse.

Most UK houses have two separate circuits (known as ring mains) for the sockets: one for upstairs and one for downstairs. Usually these are each on a 30 or 32 amp breaker. So although you can only draw 3,120W off one socket, you can draw 7,200W (30 amps x 240 volts) total off one floor’s sockets.

Always carry spare fuses
Always carry spare fuses

The first thing the gaffer should do on arriving at a location is to find the fusebox to check how many ring mains there are, where they are and what amperage of breaker they’re on. Beware that large commercial/industrial buildings may have multiple fuseboxes in different parts of the building. Make sure you have access to all of them so you can reset any circuit breakers you trip.

Also ensure you have a supply of fuses in case you blow any in the plugs of your lights or extension leads. When a bulb blows due to reaching the end of its natural life it will take the fuse with it.

Check the wound and unwound ratings of your extension reels
Check the wound and unwound ratings of your extension reels

You need to make sure your cabling is appropriate for the load you’re drawing. Extension leads can melt if you try to run too much power through them. All extension reels will have two maximum wattages written on the front of them: one for when the reel is fully wound, and one for when it’s fully unwound. When the cable is wound up it can overheat very easily, so pay attention to those quoted limits.

16 amp C form plug
16 amp C form plug

Professional hired kit is often fitted with heavy duty cabling, signified by round blue “C form” plugs and sockets. C form outlets can be found in soundstages and factories, on generators and occasionally on exterior walls of houses. They are weather resistant, so much safer for use outdoors than domestic cabling.

32 to 16 amp jumper
32 to 16 amp jumper

The associated cable comes in 16 amp and 32 amp flavours, the latter being thicker with larger plugs and sockets. A 13 to 16 amp jumper – a short adapter cable with an ordinary square UK plug on one end and a 16 amp C form socket on the other – will enable you to plug an appliance with a smaller C form plug into a standard domestic socket. Jumpers exist in every other possible direction and combination too, so it’s important you get the right ones.

13 to 16 amp jumper
13 to 16 amp jumper

Also remember that, although a 13 to 32 amp jumper will let you physically plug, say, a 4KW HMI into a domestic wall socket, that 13 amp plug will not support a 4KW load; you’ll blow the fuse. In fact if something has a 32 amp plug on it then the only way to run it safely off a house is to have a qualified electrician wire a 32 amp socket into the fusebox. Definitely don’t try to do that yourself.

In fact if you’re in any doubt about any of the above, consult an experienced gaffer or electrician. Be safe!

The First Musketeer was my first period production as DP. It’s a genre that brings its own set of challenges and opportunities, most obviously for sets and costumes, and also sound (we spent a lot of time waiting for cars and planes to pass by), but for cinematography too. The first thing that hit me was the restrictiveness of it. Back in the day there were only three sources of light: the sun, the moon and fire. And maybe, at a pinch, starlight.

Blue "moonlight" and orange "firelight" - in this case both created by gelled Dedolights
Paul McMaster as Ghislain. Blue “moonlight” and orange “firelight” – in this case both created by gelled Dedolights

I kept colour temperatures simple by deciding that daylight would always appear white, moonlight would be +2,400K (blue) and firelight would be -2,400K (orange). In practice this meant that daylight scenes were white-balanced at 5,600K using natural light, HMIs and kinoflos, with ungelled redheads or dedos for candlelight, while night scenes were typically white-balanced at 3,200K which turned HMIs and kinos blue for moonlight/starlight, with redheads or dedos gelled with full CTO to turn them orange on camera.

This night exterior shot of Lazare (Tony Sams) and Athos (Edward Mitchell) was shot with a white balance of 3,200K, turning the HMI backlight blue, while the warm light around the taven entrance was provided by CTO-gelled Dedos and redheads.

Occasionally I used straw gels to give “firelight” more of a yellow hue than an orange one, and in one scene involving a church I introduced strongly yellow light and some pink backlight, the theory being that stained glass windows could be held accountable.

A 2.5K provides the frontal keylight here, while a redhead sporting Minus Green gel provides the pink backlight. A second redhead double-gelled with Light Straw uplights the figure of Christ on the back wall, and finally a 1.2K HMI at the rear of the building illuminates the stained glass window.

I think it’s very important to soften the images when shooting a period piece digitally. Initially we hoped to do this by using Cooke lenses, but they proved unobtainable on our budget. It was too late to look into filters by this point, so instead I relied on smoke in most scenes to diffuse and age the image.

Like everyone, I continue to learn with every project that I do. Reviewing the rushes towards the end of the shoot, I realised (a little too late) that texture was the key to making the period convincing. There was bags of it in front of me – in the stone walls of the locations, in the beautifully-aged costumes, in the detailed set dressing. It was an era before smooth surfaces. I can now see that my cinematography was most successful when the lighting brought the textures out.

A 1.2K HMI outside the door cross-lights the stonework, while smoke volumizes this light, resulting in a very satisfying depth and texture. The only other light sources are two kinoflo Barflies hanging from polecats above the bench at the back of shot. This backlight is reflected back at the foreground characters by a sheet of silver foamcore beneath the camera.

Contrast the shot above with the one below. This location had equally nice stonework, but because I didn’t cross-light it it looks flat and artificial, like a cheap panto set.

A 2.5K HMI supplies the backlight here, while a blue-gelled redhead out of the top right of frame is aimed down the steps to pick out the characters as they descend. An orange-gelled Dedo creates a pool of light around the candle, and everything else is natural bounce off the surrounding stonework. A second blue-gelled redhead at the foot of the stairs firing across the stonework would have made all the difference to the believability of the environment, but hindsight is 20/20.

So that’s an important lesson I’ve learnt to take forward to the next season. Next time around I also want to play more with different colours of daylight, using more straw, amber and pink gels to stretch out the colour palette and suggest different times of day.

And then there’s the whole candlelight thing – but I’ll save that for my next post.

Know Your Lights

Whilst prepping for The First Musketeer here in the south of France I was able to record this video blog showing the lighting kit we’ll be using and what it all does. If you don’t know your kinos from your dedos, or can’t can understand why a 2.5K HMI is SO much better than a 2K blonde, this vlog will shed some light [groan].

The first week of the adventure is drawing to a close, although we only started shooting two days ago, the rest of the week having been taken up by travel and prep.
After picking up the lighting kit from Panalux and Filmscape on Monday, we set off in a convoy of five vehicles first thing on Tuesday morning from High Wycombe. After a noon crossing from Dover to Dunkirk we drove all afternoon and most of Wednesday to get to Puy L’eveque, the medieval town in which we’re based.
The main task on Wednesday was to test the workflow of the Black Magic Cinema Camera kindly lent to us by gaffer Richard. This is my first time working with the BMCC and I’ll share my thoughts on it in a forthcoming vlog.
Shooting began on Thursday, coinciding with a storm which broke the sweltering hot spell and has seen pretty much continuous rain become the dominant weather since then. There were challenges with horses, generators and (as ever) time, but as of this writing we’re on schedule and everyone seems to be very happy with the footage acquired.
I’m not sure how much I’m allowed to reveal about the series and the details of what we’ve been shooting, so I’ll leave it there. Stay tuned for more video blogs.

Understanding Colour Temperature

An updated version of this article is available.

As I was writing my last entry, in which I mentioned the range of colour temperatures in a shot, it occurred to me that some readers might find an explanation of this concept useful. What is colour temperature and why are different light sources different colours?

The answer is more literal than you may expect. It’s based on the simple principal that the hotter something burns, the bluer the light it emits. (Remember from chemistry lessons how the tip of the blue flame was always the sweet spot of the Bunsen Burner?)

Tungsten bulbs emit an orange light - dim them down and it gets even more orangey.
Tungsten bulbs emit an orange light – dim them down and it gets even more orangey.

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. So the temperature here in Hereford right now is 296 kelvin (23°C).

The filament of a tungsten light bulb reaches a temperature of roughly 3,200K (2,927°C). This means that the light it emits is orange in colour. The surface of the sun is about 5,778K (5,505°C), so it gives us much bluer light.

Colour temperature isn’t necessarily the same as actual temperature. The atmosphere isn’t 7,100K hot, but the light from the sky (as opposed to the sun) is as blue as something burning at that temperature would be.

Digital cameras have a setting called “white balance” which compensates for these differing colour temperatures and makes them appear white. Typical settings include tungsten, daylight, shade and manual, which allows you to callibrate the white balance by holding a white piece of paper in front of the lens as a reference.

Colour temperature chart

Today there are many types of artificial light around other than tungsten – fluorescent and LED being the main two. In the film industry, both of these can be obtained in flavours that match daylight or tungsten, though outside of the industry (if you’re working with existing practical sources) the temperatures can range dramatically.

There is also the issue of how green/magenta the light is, the classic example being that fluorescent tubes – particularly older ones – can make people look green and unhealthy. If you’re buying fluorescent lamps to light a scene with, check the CRI (colour rendering index) on the packaging and get the one with the highest number you can find for the fullest spectrum of light output.

The Magic Lantern hacks for Canon DSLRs allow you not only to dial in the exact colour temperature you want, but also to adjust the green/magenta balance to compensate for fluorescent lighting. But if two light sources are giving out different temperatures and/or CRIs, no amount of white balancing can make them the same.

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 classic practical example of all this is a person standing in a room with a window on one side of them and a table lamp on the other. Set your camera’s white balance to daylight and the window side of their face looks correct, but the other side looks a nasty orange (above left), or maybe yellowy-green if the lamp has an energy-saving bulb in it. Change the white balance to tungsten or fluorescent and you will correct that side of the subject’s face, but the daylight side will now look blue (above right) or magenta.

This is where gels come in, but that’s a topic for another day.

The beauty of modern digital cinematography is that you can see how it looks in the viewfinder and adjust as necessary. But the more you understand the kind of theory I’ve outlined above, the more you can get it right straight away and save time on set.

Depth Cues in Cinematography

One of the most important jobs of a director of photography is to help the viewer’s brain decode the image. Just as a sound mixer must get the cleanest possible dialogue and ensure that ambience, music and effects don’t distract from it or drown it out, so a cinematographer must ensure the eye is drawn to the character and not distracted by the surroundings.

Depth is a key part of creating this clarity. Christopher Nolan once said: “95 percent of our depth cues come from occlusion, resolution, color and so forth, so the idea of calling a 2-D movie a ’2-D movie’ is a little misleading.”

This week, on The Deaths of John Smith, I photographed a shot that used every trick in the book to create depth. Why? Because it was a one-shot scene, a flashback taken out of context, and the audience needed to “get it” quickly.

When I first set the camera up and we stood John (played by Roy Donoghue) in position, his dark suit melted into the dark wood panelling behind him, so there was clearly some work to do. Once lit, as you can see from these frame grabs, he stands out sharply.

Let’s look at the depth cues going on here.

  1. DEPTH OF FIELD. Although I’m shooting at f1.8, on a 20mm lens nothing is massively out of focus, so that isn’t helping much.
  2. SMOKE. There is more smoke between the camera and a distant object than between the camera and a close object, and therefore smoke aids depth perception.
  3. CONTRAST. The foreground is darker than the background, helping the eye to distinguish between the various layers. In particular, the smoke picks up the light from the windows at the back of the room, creating a blue-white haze against which John’s dark suit stands out clearly, as does Sarah’s silhouette.
  4. COLOUR CONTRAST. The foreground is lit with warm orange, while the background is a cool blue, again enhancing the separation between the layers. (Imagine you’re standing on a hill and looking at another hill in the distance. That distant hill looks much bluer than the one you’re standing on, due to atmospheric haze. The smoke and colour contrast mimic this effect.) For most of this film I kept all the light sources within about 1,500K of each other, but in this scene I deliberately allowed more like 3,000K of difference between warm and cool sources to give the flashback a more stylised look.
  5. BACKLIGHT. John has a little edge-light on his righthand side, ostensibly from the wall sconces, but in reality from a hidden Dedo. This helps to cut him out from the background.
  6. FRAMING. The doorway frames the image, adding an extra layer of depth.
  7. PARALLAX. This is the optical phenomenon whereby, when you move your head (or a camera) things closer to you appear to move more than things further away. By dollying slightly into the room behind Sarah we create a dramatic parallax effect as the doorway grows on camera much more than John and the room behind him.

I’ll leave you with my (retrospective) lighting plan for this scene. Be sure to check out the film’s official website at www.thedeathsofjohnsmith.com

How to Light a Church

Background light comes from two 500W halogen work-lights rigged to a dimmer, while fill (given that it was getting dark outside at this point) comes from a blue-gelled 1K Arrilite behind and to the left of camera.

This weekend shooting began on Roger Harding and Darren Scott’s feature-length comedy The Deaths of John Smith. As director of photography I was called on to light a beautiful rural church on a limited budget. Here are some tips for ecclesial cinematography:

  • Hire HMIs – powerful, daylight-balanced lamps. Without at least one you will never have enough light to illuminate anything but the tiniest of churches. As a backlight on a mezzanine level, a 2.5K HMI will illuminate most churches. Better still, put them outside the windows and create artificial sunbeams. (A blue-gelled blonde or redhead outside a stained glass window is pretty much useless; those windows cut out so much light.)
  • Use smoke. A £50 disco smoke machine is perfectly sufficient – use it to volumize the light and emphasise the depth and scale of the building. If you’re struggling to expose a bright enough image, smoke helps there too – because it catches the backlight and lightens up the shadows.
  • Candlelight is a good way to introduce colour contrast into your scene. Dedos are the best lamps to fake candelight with, as they can produce a small circular pool of light. Failing that, any tungsten source will do, ideally rigged to a dimmer board for a bit of flickering.
  • Assuming you’ve got your HMIs punching directly in through all the windows on one side of your church (that’s the side the “sun” is on), you now need soft light coming in through the opposite windows. Ideally these would be larger HMIs playing off bounce boards, but you might get away with soft boxes or bounced tungsten sources (gelled blue, of course) hidden behind pillars inside the building.
  • Sellotape together some old bits of coloured gel and rig them in front of a fresnel to simulate daylight through a stained glass window. Note that this doesn’t really work with unfocused lamps like redheads.

A blue-gelled 1K Arrilite off to the right of frame creates the edge-light on the righthand side of each character. An existing halogen spotlight over the organ was gelled with half CTB to cool it down a little. I chose to leave the nearside of the characters dark to contrast the foreground with the brighter background.

On The Deaths of John Smith I only had access to one HMI, so for every shot I needed to carefully choose which window to put it outside of for the maximum impact. I relied on natural light as well as blue-gelled redheads and fluorescent softboxes just out of frame for fill light. Nonetheless, I’m very pleased with the results. Next weekend we have to repeat the performance with a large congregation….
