Earlier this year I blogged about a visit to the National Portrait Gallery, studying the lighting in traditional portraits. I noted that, contrary to the current cinematographic trend for short key lighting, almost all of those paintings used broad key. And while watching the high-end Netflix series The Crown this week, I noticed the same thing. Why might this be?
First of all, a reminder: a short key is a key light on the side of the face away from camera, while a broad key hits the side of the face towards camera. Short key is generally preferred amongst cinematographers because it gives better “modelling” – i.e. a better sense of the shape of the face – and focuses the viewer ON the face, rather than the ear and the side of the head. A broad key, meanwhile, presents less shadow to the camera, and arguably shows the hairstyle and the shape of the head better – which may be reasons for the preponderance of broad key in classical portraiture, which were more concerned with overall appearance than with emotion/performance.
But I don’t believe these direct pros and cons were the primary motivation in cinematographer Ole Bratt Birkeland’s decision to use broad key lighting in a crucial scene from The Crown.
The central themes of the series, which dramatises the early life of the Queen, are tradition and duty. Queen Mary often reminds her granddaughter Queen Elizabeth II of the long and noble lineage of the English royal family, a weight of history and responsibility which Elizabeth keenly feels. “The crown must always win,” Mary intones in the trailer.
In episode 4 the young Queen seeks advice, desperate to ensure she does not tarnish the monarchy’s centuries-old reputation. To symbolise this burden, Birkeland evokes the imagery of traditional portraiture – the subjects of which were always high-born individuals, often royals. Consider this frame grab from the scene, beneath an official portrait.
See how the light models the face the same way in both images? Note also the absence of backlight in the frame grab, another feature common to traditional paintings, which typically relied on a single window light source. Elizabeth’s dark hair blends into parts of the dark background.
Combined with the timeless regal production design, this lighting subtly places the Queen within the frame of an official portrait, trapping her within the overwhelming tradition of the monarchy. Can I say for certain that Birkeland did this deliberately? No, but I’d be very surprised if he hadn’t looked at royal portraits while prepping the show, and I’d be equally surprised if they hadn’t at least influenced him unconsciously.
Either way, this is a first-rate example of the power of cinematography to enhance theme and narrative by guiding the viewer to make subconscious associations. If you haven’t seen The Crown, I can highly recommend it; it’s not just the cinematography that’s top notch.
Following on from my ‘Know Your Lights’ overview last week, today I’ll look in more detail at the first category of lamps and the various units available and when you might use them.
And that first category is incandescent lighting, commonly known as tungsten. It is the oldest, simplest and most robust lighting technology. Tungsten lamps are the cheapest to hire, the easiest to repair, and emit a smoother spectrum of light than any other artificial sources, making for the most natural skin tones. For my money, there’s no better way to artificially light a human face than by bouncing a tungsten source off polyboard.
Tungsten lighting units can be sub-categorised by the style of reflectors and/or lenses in the heads…
The simplest instruments are known as ‘open-face’ because they have no lens to focus the light. By far the most common units are the 800 Watt and 2,000 Watt models. These are often referred to as ‘redheads’ and ‘blondes’ respectively, though I strongly discourage these terms for reasons touched on here. 300W models – dubbed ‘Lilliputs’ by manufacturer Ianiro – are also available, as well as 1Ks and much larger models like the Mole-Richardson Skypan 5K and Skylite 10K.
While I have lit entire no-budget features with just open-face lights, on larger productions the uneven and unfocused nature of their light makes them a poor relation of other units on the truck. They are most likely to get fired into a bounce board or used to create a little pool of light somewhere in the deep background where finesse is not needed.
The fresnel lens was invented in the early 19th century by French physicist and engineer Augustin-Jean Fresnel in order to increase the focus and throw of lighthouse lamps. Today in the film industry, fresnel lenses can be found on tungsten, HMI and even LED fixtures.
Tungsten fresnels come in the following wattages: 150W, 300W, 650W (a.k.a. ‘tweenie’), 1K, 2K, 5K, 10K, 12K, 20K, 24K.
1Ks and 2Ks are sometimes called ‘babies’ and ‘juniors’ respectively, but confusingly those terms can also refer to whether they are the smaller location models or larger studio versions of the same wattage.
Though the fresnel lens reduces the light output a little, the beam is much more focused and can therefore create a shaft of light through smoke, which open-face lamps cannot. Hence I sometimes use tungsten fresnels to simulate hard sunlight when shooting on a stage. But beware that shadows cast by a fresnel can sometimes show up the ridges in the lens.
I often fire fresnels into bounce boards, and because their light is more focused they require less flagging to control the spill than open-face units.
Par lights use a parabolic (shaped like half a rugby ball) reflector and a lens to produce a soft-edged oval pool of light. They are extremely common in theatres, but are often used in film and TV as well.
Unlike fresnel and open-face units, par cans are referred to not by wattage but by the diameter of the bubble in eighths of an inch. So a Par 16 (a.k.a. ‘birdie’) has a 2″ bulb.
Par cans come in the following sizes: 16, 20, 36, 38, 46, 56, 64. They also come with various internal specs which affect the width of the beam.
Par cans are good for throwing shafts of light. On The Little Mermaid I used them to simulate car headlights, and as practicals (i.e. they were seen on camera) to uplight banners at the circus.
Maxibrutes (a.k.a. ‘Molepars’) are banks of multiple par 64 (1KW) lights. They come in banks of 4, 6, 9, 12 or 24. They pop up in the background of music promos quite often, because they look cool and kind of retro. I used two 9-light Maxibrutes, bounced off the tent roof, to illuminate the big top in The Little Mermaid. Some DPs like to use Maxibrutes for backlight on night exteriors. If you’re using them direct, you’ll need at least a sheet of diff to prevent multiple shadows.
Minibrutes (a.k.a. ‘fays’) are similar, but use smaller par 36 (650W) lamps.
Dedolites are compact units that use a unique lens system to produce very focussed, controllable light from (most commonly) 150W bulbs. They are widely available to hire, come with in-line dimmers, and are small and light enough to be rigged overhead or in tight spots. I often use them to beef up practicals.
Source Fours or (a.k.a. ‘lekos’) are ellipsoid reflector spotlights. They feature cutters which can be used to shape the beam, they can be hired with different lenses (some of which are zoomable), and they can be fitted with gobos to project patterns. They are good for stylised pools of light or for firing into distant bounce boards without spilling light elsewhere.
Finally, tungsten is usually the most desirable type of bulb to use in practicals. It is commonplace when shooting a daylight interior for a spark to go around replacing the energy-saver fluorescent bulbs in the table lamps with old-school tungsten ones. The colour is much nicer, the skin tones are better as noted above, and they can be dimmed to just the right level for camera.
I’m sure I’ve missed something out – please feel free to let me know on Facebook or Twitter! Next week: HMIs.
