“Above the Clouds”: February 2017 Pick-ups

Last weekend saw many of the crew of Above the Clouds reunite to shoot the remaining scenes of this comedy road movie. Principal photography was captured on an Alexa Mini during summer 2016 on location in Kent, on the Isle of Skye, and at Longcross Studio in Buckinghamshire, with additional location shooting on a Blackmagic Micro Cinema Camera in October.

The outstanding scenes were to be photographed on stage, at Halliford Studio in Shepperton, this time on an Arri Amira. The Amira uses the same sensor as the Alexas, allowing us to match the look from principal photography in the most cost-effective way. With the addition of a Premium license, the camera is capable of the same ProRes 4444 recording codec as the Alexas too. As per last summer, our glass was a set of Arri/Zeiss Ultra Primes, with a half Soft FX filter to take the digital edge off.

Director Leon Chambers designed and built the set himself, sending me photos of a scale model well in advance. He was also specific about certain lighting cues and states that were required across the two sets and six scenes we would be recording to complete the movie. Based on this information, I concocted a lighting plan, which I communicated to Halliford’s in-house gaffer Micky Reeves by Photoshopping stock images of lamps onto Leon’s set model photos.

Last Saturday was devoted to pre-lighting the sets, mainly the kitchen, while construction work continued on the second set.

 

Day 24 / Sunday

We begin with a morning scene. A 5K fresnel serves as a low sun, streaking across the back wall of the set (see my post about lighting through windows). Even with this direct light four stops over, the natural bounce off the set isn’t enough to bring actor Philip Jackson – with his back to the window – up to key. Micky rigs a Dedo firing into a soft silver bounce just out of frame to solve the problem.

Also coming through the window are two 4×4 kinos, rigged on goalposts above the window. Their daylight tubes reflect off the blinds, serendipitously creating the illusion of a blue sky “outdoors”, where in fact there is only a wall and a white backdrop.

Philip exits into the hallway and disappears from view, supposedly to go out through the front door. No door exists. Instead there is a flag which spark Amir Moulfi rotates in front of a 2K, creating a momentary oblong of light in which Philip’s shadow appears.

The next scene follows on from an exterior captured last October at dusk, when the natural light was soft, flat and cool in colour, cheated even cooler with the white balance. This failing daylight is to be the only source of illumination now in the kitchen set, until Philip enters and turns on the lights. This is the main reason that the daylight 4×4 kinos outside the window were rigged. A third kino from the direction of the front door is added, plus a small LED reporter light to pick an important prop out of the shadows.

Lead actress Naomi Morris enters, silhouetted against the windows. Then Philip enters and hits the lights. Simultaneously, Amir flips a breaker on a lunchbox, activating a hanging practical fixture above the breakfast bar and the 5K which that practical motivates.

Generally I don’t like toplight. It throws the eyes – those windows to the soul… or windows to the performance – into shadow. But with the hanging practical in shot, whatever I was going to use to beef it up had to be somewhat toppy or it wouldn’t make sense. I considered space-lights and Jem balls, but in consultation with Micky I ultimately picked a 5K with a chimera, coming in at a 45 degree back/toplight angle. As you can see from the photos, this looks almost comically large. But large and close means soft, which is what I want. It had to be soft enough to wrap both actors when they faced each other across the bar.

 

But why such a large lamp? Why not use a 2K, like Micky suggested yesterday? Bitter experience has always taught me to go with a bigger unit than you think you need, particularly if you’re softening it, and particularly if it’s going to take a while to rig. (The 5K was hung from another goalposts set-up.) We ended up dimming the 5K to 50% and scrimming it down a stop and a half. But having too much light like that is easy to deal with. If we had put up a 2K and it wasn’t bright enough, we would have to have taken the whole thing down and re-rigged with a 5K. And even if the 2K had seemed sufficient to begin with, blocking can often take actors into unexpected, dark corners of the set. Being able to turn up a dimmer a couple of notches to handle that kind of situation is very useful.

Besides the 5K, there are a few other sources playing: some 300W hairlights, a pup bouncing off the side of a cupboard to bring up the area around the cooker, a China ball in the hallway, and Leon’s Rosco LitePads serving as practical under-cabinet down-lighters.

 

Day 25 / Monday

I probably shouldn’t say what today’s set is, because it’s a little bit of a spoiler. There are some lighting similarities to the kitchen: again we have a character flicking a light switch, bringing on two hanging overhead practicals and a 2K with a chimera to beef them up.

A practical lamp on a desk was supposed to be turned on during the scene as well, but we all forget until it’s too late. It would have bounced off the desk and given Philip a little eye-light, and at first I regret losing this. But soon I realise that it is more appropriate for the scene not to have that level of refinement, for the lighting to be a little raw. The toppy, “broken key” angle of the chimera’s light works well for this tone too.

We wrap just before noon, releasing Naomi to high-tail it to Oxford to appear on stage in a musical this evening. Eventually there will be second-unit-style GVs and establishing shots to do, but there will only be three or four of us for that. For the cast and most of the crew, today brings Above the Clouds to an end, eight months after the camera first rolled.

“Above the Clouds”: February 2017 Pick-ups

Lighting Micro-sets

From time to time I help out my friend Kate Madison shooting show reels for actors. The fun and the challenge is in creating and lighting little micro-sets to capture angles that look like they might be lifted out of a scene from a much larger production, all with limited equipment.

lawyer-grade-moresat
Here’s an interesting shot from a recent showreel for Dana Hajaj. This was intended to resemble a Good Wife style legal drama, though actually the first reference that the lawyer’s office setting brought to my mind was Ally McBeal. I remember how they often had hot sunlight coming in through their office windows which would hit the talent from the chest down, while softer, indirect daylight would illuminate the faces.

Clearly this technique wasn’t exactly going to work for an MCU, but it did get me thinking about windows as two-in-one sources: a hard source which adds interest and ‘sheen’ to the image but is too harsh to hit faces with, and a soft sources for faces. Often cinematographers will use two different lights through the same window to achieve these two distinct effects. (I sometimes employ what I call a “Window Wrap” to this end.)

Now, the set for this showreel shot was just a red wall and sconce. (We tried a plant in the corner but couldn’t get it to work.) I wanted to suggest what the rest of the set might be, beyond the borders of this MCU, and simulating a window seemed like a natural choice. Furthermore, a window with Venetian blinds would help sell what was really a living room as a place of business. But this was not film noir; I didn’t want stripes of light on Dana’s face. Instead I used them to add interest to the wall.

Kate had a slatted-top stool in the hall which threw convincing “blinds” shadows when clamped to a C-stand in front of an 800W Arrilite. Ideally the shadows would have been sharper, but without a Dedo or a par this was the best I could do.

To get the maximum richness from the practical, I put a topper (black wrap clipped to the stool!) on the 800 to keep it off the sconce, and placed CTO inside the lampshade to warm up the fluorescent bulb.

To key Dana, I fired a 1K Arrilite into a 4’x4′ polyboard which was positioned next to the stool. Tungsten bounced off poly gives a beautiful soft, matt quality of light, and is a great way to key talent.

The backlight comes from a 1’x1′ LED panel set to about 4500K. What is the motivation for this source? North light coming from another window maybe? The great thing about micro-sets is there’s no wide shot so I don’t have to worry about that if I don’t want to! The motivation is that cold backlight looks good on black hair, and that’s that.

img_1344

As we prepared to roll, I wondered if I should increase the contrast more. I could have done this by (a) flagging the poly bounce to prevent it filling in the “blinds” shadows on the wall and (b) bringing in negative fill on the talent’s camera right side to kill the ambience. But I decided that more contrast was not appropriate for this kind of piece.

For another scene for Dana’s reel, we mocked up a remote Arabian campsite on Kate’s patio! Kate used a piece of fabric hung from a post and two light stands to representing the tent.

campsite-grade-moresat

I wanted to give the impression that if we cut to a wide shot – which of course we never do, but if we did – that it would show a vast landscape, perhaps a desert, all backlit by moonlight. On this hypothetical production, I would generate that moonlight with 18Ks on condor cranes, gelled with Steel Blue.

But on this tight shot I was able to achieve the same effect with two far smaller sources, both gelled with Steel Blue. (This is a blue with more green in it than CTB. It’s prettier and has connotations of many 80s and 90s thrillers and action movies that seemed to use copious amounts of this gel.) In the deep background is an LED panel, 3/4 backlighting a couple of blurry apple trees that could maybe play as vegetation around an oasis. Immediately behind the “tent” is a 40″ C-stand, top floor, with a 1K Arrilite on it. So close to the talent, the 1K comes down at a steep enough angle to imply moonlight, or an 18K on a condor, depending on how you want to look at it.

The flames from the fire pit weren’t doing much to light Dana, so I bounced another 1K off a gold reflector on the floor next to the fire. During takes I wiggled the reflector to add dynamics to the light.

To add a final touch of production value, I suggested a foreground practical. Kate found a candle lantern which we hung from a flag arm just in front of camera. Every frame of a Blockbuster movie is packed with details, so things like this help a lot to sell the scale.

img_1308
The 1K “moon” backlight is at top left. The gold reflector for the fire source is in the bottom centre, with the 1K bouncing into it visible two-thirds of the way down the right-hand edge of this image. The camera is just out of the bottom right corner of this frame. Not pictured is the LED background light, way back off left of this frame.

Lighting Micro-sets

Know Your Lights: LED

In this final part of the Know Your Lights series, I’m taking a look at some of the LED fixtures currently available.

In this frame from Ren: The Girl with the Mark, Hunter's face is lit by a small LED reporter light hidden behind the bucket to suggest a reflection off the water.

LEDs (light emitting diodes) generate light through electroluminescence. When a controlled direct current is applied to the electrodes, electrons in the semi-conductor reconfigure, releasing energy as light. LEDs have been around since the early sixties, but for decades they were only capable of emitting a weak red glow, restricting their applications to things like TV standby lights and digital clocks. In recent years the brightness and colour range of LEDs has improved dramatically, making them practical alternatives to traditional light sources.

Compared with those sources – tungsten, HMI and fluorescent –  LEDs are more efficient, lighter, generate less heat, have a longer life, and are less likely to break and less dangerous when they do. They are fully dimmable, without the colour temperature changing, but if you wish, some fixtures allow you to alter the colour temperature with the turn of a knob.

On the down side, LED units are expensive, lack the raw power of large HMI or tungsten fixtures, and can often suffer from poor CRI (colour rendering index – see the overview for more info).

The technology is improving rapidly, and LEDs will only get better over the coming years. For now, many regard them as speciality lights, and they are almost always outnumbered by tungsten, HMI and fluorescent units in a drama lighting package. But some productions have really embraced them, an example being Guardians of the Galaxy, where many of the colourful practicals built into the sets were LEDs. Because they can be squeezed into smaller spaces than any other kind of light, and because you can get around the poor CRI by using coloured lamps, or gelling white ones, LEDs are well suited to creating practical glows from computers, control desks and other technology.

These are just a few of the LED fixtures currently on the market…

 

Panels

LP-1x1 Bi-color LitePanel
LP-1×1 Bi-color LitePanel

1’x1′ LitePanels are perhaps the most common LED unit. These panels have two dials on the back: one for brightness, and one for colour temperature (3200-5600K). They can be run off mains or a V-lock battery, drawing 40W to output about as much light as a 200W HMI.

I usually ask for a couple of these panels in my package, and they are great for situations like these:

  • As you are about to roll, you spot an area of the frame that needs a little extra splash of light. It is the work of moments to slap a battery on a LitePanel and fly it into shot.
  • A light needs to be situated in a tight space in the set, or in a spot which a power cable couldn’t reach without appearing in frame, or both. The fact that you can just prop these panels up against the set without worrying about them getting hot and damaging something is huge.
  • When required to shoot a night exterior without a generator, LED panels can really help you out. Even if you do have a genny, the ability to set up a source without running power to it is extremely useful. A short film I shot called Forever Alone is a good example.
  • Wrapped in a diffuser like tough-spun or muslin, they make good fill lights or eye lights for day exterior close-ups.
  • They can make good TV sources, particularly if your set-up time is limited. A spark can twiddle the brightness and colour temp dials during takes to simulate changing images on the TV screen.

There are many manufacturers producing panels in 1’x1′ and other sizes, but LitePanels are the best ones I’ve encountered. However, I’ve yet to come across any LED unit with a good enough CRI to use as a key light.

A range I haven’t used is the Arri SkyPanels. Designed primarily to be rigged overhead from studio grids, they come in 30, 60 and 120cm lengths. The coolest thing about these units is that you don’t need to gel them; just punch in the Lee or Rosco code of the gel you want to use, and the light instantly changes colour!

Rosco Lite Pads go for a slightly different approach. The LEDs are arranged around the edges of these panels, and bounce off the white backing to produce a soft daylight source. They’re not very bright, and again the CRI is not great, but the range of shapes and sizes they come in mean that you can find one to fit most tricky spaces.

Two 3″x12″ Rosco LitePads taped to the dashboard of the picture car in Above the Clouds

I used these a lot on Above the Clouds (check out the blog posts) in many different situations. Two 3″x12″ Lite Pads saw extensive use as fill/eye light, taped to the dashboard of a Fiat 500 in driving scenes. The other standard sizes are  3″x6″, 6″x6″, 6″x12″, 12″x12″ and 3″ circular. The panels themselves are stripped down, so batteries and dimmers can be sited remotely.

Rosco also makes LitePad Vectors, which are more like other brands of LED panel, with on-board dimmers and increased light output, and they can even make custom LitePads.

Fresnels

Several companies make small fresnels which at first glance appear to be HMIs, but are in fact LEDs. LitePanels make the Sola 6C and Sola ENG, equivalent to 200 and 100W HMIs respectively. Arri makes the L5, L7 and L10 units, which are each available in three models with differing brightness and colour-tuneability characteristics. The brightest L10 models are comparable with a 2K tungsten fresnel, while drawing a fifth of the power.

There are budget models out there too, such as the NiceFoto CE-1500Ws, which I used a little on Ren: The Girl with the Mark. As with all budget LED and fluorescent lights, the CRI is very poor, but it was useful when we lacked enough traditional fixtures.

Overall, LED fresnels are currently most relevant in scenarios where power is very limited, or portability and lack of heat is particularly important – in a nutshell, electronic news-gathering (ENG).

 

Ribbons

One of the most exciting things about LEDs is that because the individual diodes are so small, they don’t necessarily have to be housed in a fixture of any kind. LiteGear, for example, supplies LiteRibbons, which are strips of LEDs “mounted to a white backing material that is flexible, cuttable and adhesive backed”. The possibilities for these ribbons are pretty much endless. Here are some examples:

  • The Enterprise bridge set featured in the last three Star Trek movies has all its control panels lit by LiteRibbons.
  • Mad Max: Fury Road, and many other movies with driving scenes, had strips of LEDs mounted to the ceiling, window frames and pillars of the truck cab to increase the exposure inside.
  • The mini reactor that powers Iron Man’s suit is illuminated by LiteRibbon LEDs.

Conclusion

Some predict that, as LEDs get brighter, cheaper and higher in CRI, they will eventually replace every other kind of lighting. For now though, they’re just another part of the toolkit in which tungsten and HMIs, and to a lesser extent fluorescents, are the go-to tools.

There is a fifth type of lighting that is emerging too: plasma lighting, but it’s so new and so rare at the moment that I don’t feel equipped to write a post about it yet. But you can read about it over on Shane Hurlbut’s blog.

Another great blog to teach you about the many lights out there is Set Lighting, written by experienced Hollywood gaffer Martijn Veltman. His site was really useful when I was researching this series.

Of course, the most important thing is not what lights you have, but how you use them. There are many, many posts here on neiloseman.com to teach you about that. Check out the Lighting Techniques series for some basics, watch my Lensing Ren video series to see how all four types of lighting are used in practice on a real shoot, or simply search the tag ‘lighting’ for a wealth of material.

Happy lighting!

Tungsten and/or HMI lamps are usually the workhorse units of a lighting package, providing the power that is needed to key-light all but the smallest of set-ups. But they’re not right for every situation. If you don’t need the punch of a point source, and you want something a little softer, fluorescents might be the answer.

This is the third category of lighting units I’m covering in my Know Your Lights series; back up to the overview if you want to start from the beginning.

Fluorescent units use very similar technology to HMIs, with electrodes exciting a gas so that it gives off UV light. The phosphor coating on the tube absorbs the UV light and fluoresces, i.e. re-emits the light in the visible spectrum. Like HMIs, fluorescent units require a ballast to regulate the current.

One of the most notable early uses of fluorescents was in Robocop (1987). Jost Vocano, ASC chose the fixtures because the long, thin reflections looked great on Robocop’s suit. The flip side of that coin is that under certain circumstances fluorescents can make actors’ skin unpleasantly shiny. There was a scene in Ren: The Girl with the Mark where the poor make-up artist had to cake layers of powder onto Sophie Skelton to combat the shine of a Kino Flo I had set up.

Robocop (1987, dir. Paul Verhoeven) – note the fluorescent strips reflected in the suit.

One way I often use fluorescents is as a “Window Wrap”, a soft source that augments a hard HMI coming in through a window to wrap the light more pleasingly around the talent’s face. Or I’ll place a fluorescent outside the room, to represent or enhance indirect daylight spilling through a doorway.

Being soft sources, the light rays which fluorescents emit spread out widely, meaning the intensity drops off quickly as you move away from the lamp. (We refer to this as “throw”: fluorescents have little throw, whereas spotlights have a lot of throw.) For this reason they start to become pretty ineffective once you get more than about 6ft away from them, depending on the model.

Kino Flo is far and away the most common brand of fluorescent lighting used in the film and TV industry today, so apologies if the rest of this post reads a little like an advert for them. They’re not paying me, honestly!

The company was started by gaffer Frieder Hochheim and best boy Gary Swink after inventing the units for the 1987 comedy-drama Barfly (DP: Robby Müller, BVK). They required a fixture small enough to tuck into little alcoves in a bar location, without getting hot and causing damage.

Kino Flos come in two different kinds:

 

4'x4 Kino Flo with remote ballast leaning against the base of the C-stand
4’x4 Kino Flo with remote ballast leaning against the base of the C-stand
4-bank Kino Flo ballast
4-bank Kino Flo ballast

Remote Ballast

With these units, the lighting fixture is separate to the ballast, and they are connected by a header cable, just like HMIs. Remote units are usually referred to by two numbers, the first representing the length of the tubes in feet, and the second representing the number of tubes. So a unit with two tubes, four feet in length, is called a “4ft 2-bank”, often written as: 4’x2 (pronounced “four by two”).

The most common units are 2’x4 (a.k.a. “fat boy”), 4’x4 and 4’x2, but others are available, including “Single Flo” units and 6ft/8ft “Mega” units.

The ballasts allow you to turn individual tubes on and off as required, and also feature a switch marked either Hi/Lo or 4ft/2ft, which reduces the light output by adjusting the current waveform.

 

Kino Flo Tegra

Built-in Ballast

As you might expected, these models combine the fixture and ballast into a single unit. They are designed primarily for interview/ENG applications where it is more convenient to have everything in one. On drama productions it is generally preferable to have a remote fixture, which will be lighter, and a header cable running to an easily accessible ballast.

One advantage of built-in models over their remote cousins is that they are smoothly dimmable down to 5%.

Built-in units are known by names rather than numbers: “Diva-Lite” (2’x4), “Tegra” (4’x4) and “BarFly”, which resembles a swollen 1’x1′ LED panel. There is also the large “Image 87”, a 4’x8 fixture with a built-in ballast. It’s great for lighting green and blue screens because it puts out so much soft light.

Kino Flo tubes are available in five colours:

  • KF55 – 5500K – i.e. daylight – identified by blue end caps on the tubes
  • KF32 – 3200K – standard tungsten – gold end caps
  • KF29 – 2900K – warm tungsten – red end caps
  • 420nm blue – an extra-saturated blue for lighting blue screens
  • 525nm green – for lighting green screens

Kino Flos often come with plastic grids known as “egg crates” or “louvres”. Their purpose is to make the light more directional, effectively polarising it on a macro scale. They come in black, silver and “honeycomb” varieties, the latter available in 45º, 60º and 90º angles so you can choose how directional the light becomes – and, as a side effect, how much intensity you lose.

It is possible to remove the tubes and wiring from a Kino Flo housing so that the lamps can be squeezed into a tight space. For example, on The Little Mermaid we needed to see a soft blue glow emanating from a small translucent compartment in an organ. Best boy “Captain” Dan Xeller removed a 2ft Kino tube from its housing and placed it inside the compartment, running the wires out the back to the ballast.

Other than Kino Flo, another brand of fluorescent lights you may come across is Pampa Lights. They come in rugged boxes which can be interlinked to create larger banks of illumination. Unfortunately, in my experience the CRI (see overview) is not good, and they are best avoided.

The same goes even more so for the many fluorescent softbox kits available on Ebay from Hong Kong sellers. Not only are they flimsy in construction and questionable in terms of electrical safety, but the CRI of the lamps is very, very poor. If you need a cheap soft source, you would be much better off bouncing a halogen work light off a white card.

Indeed, firing an incandescent source into a bounce board will give you a better quality of light than even a Kino Flo. But a fluorescent fixture won’t make the room unbearably warm, it can emit daylight-balanced light, and it’s quicker to set up than a bounce board and the attendant flags. In a nutshell, it’s more convenient.

Next week, the Know Your Lights series concludes with a look at the fast-evolving world of LED illumination.

Know Your Lights: Fluorescent

Know Your Lights: Tungsten

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.

This comparison of domestic bulbs against daylight shows the spectra of light they emit.

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.

Fresnel lens

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.

On Heretiks we used numerous 300W and 650W fresnels to beef up candlelight, often placing tough-spun diffuser over them, dimming them down to warm up the colour temperature, and flickering them too.

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.

Dedolite

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.

ETC Source Four
ETC Source Four

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.

Spacelights

Spacelights are wagon-wheel configurations of three or six 1K lamps inside a cylinder of diffusion material. They are normally used in large numbers to provide ambient toplight on stage. Click here for a brief video introduction to spacelights.

1K Jem ball
1K Jem ball

Jem Balls, or China balls, resemble Chinese paper lanterns. They come in 22″ (up to 1KW) and 30″ (up to 2KW) sizes and produce a very soft light which I personally find is never bright enough.

Bare bulbs (usually referred to as ‘globes‘) in pendant fittings can be hung from overhead or hidden behind set dressing, perhaps to beef up practicals. On Ren: The Girl with the Mark and other projects I hid some globes behind furniture to enhance the pool of light from candles.

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.

Know Your Lights: Tungsten

Know Your Lamps: Overview

Welcome to the first in a series of posts looking at the many types of lighting instruments in use on film and TV sets today. This is not intended to be an exhaustive or comprehensive list, but it will give you a good idea of your options, particularly if you’re moving up from smaller productions – where lighting kit is mostly borrowed – to larger ones, where you’re required to submit a lighting list to a rental house.

Some of the key considerations when choosing a lamp are:

  • Colour temperature – how orange or blue the light appears – see this post for more info
  • CRI – Colour Rendering Index – how full a spectrum of light is emitted, and therefore how accurately colours are rendered
  • Light quality – how hard or soft the light is
  • Power consumption
  • Hire cost

Lamps can be divided into categories according to the means by which they produce light. Here is an overview of the main types.

 

Redheads draw 800W each

Incandescent (view detailed post)

Incandescent lamps work by passing electrical current through a wire filament which becomes so hot that it glows. In the film industry they are generally referred to as ‘tungsten‘ units after the metal which the filament is made from. Common tungsten lamps include Dedolites, 1K ‘babies’ and open-face 800W and 2KW units (which have misogynous nicknames I shall not repeat here).

Pros: cheap, dimmable, extremely high CRI

Cons: very inefficient, get very hot, colour temperature changes when dimmed

Colour temperature: 3,200K

Light quality: generally hard (although certain units like Space Lights are softer)

 

HMI fresnel

HMI (view detailed post)

The HMI (hydragyrum medium-arc iodide) is the most common form of high intensity discharge lamp used in the industry. It operates by creating an electrical arc between two electrodes which excites a gas. You may occasionally hear about an MSR (medium source rare-earth), which is slightly different technology, but as far as a cinematographer is concerned MSRs and HMIs are the same. They require a ballast to ignite the arc and regulate the current and voltage.

Pros: good CRI, good match for daylight, efficient

Cons: only dimmable down to 50%, expensive, heads and ballasts sometimes hum or ‘squeal’, older bulbs can vary in colour, flicker issues at certain shutter angles with magnetic ballasts

Colour temperature: 5,600K

Light quality: hard

 

Kino4x4Fluorescent (view detailed post)

Fluorescent lamps are found almost everywhere today, as strip lights in supermarkets and offices, and energy-saver bulbs in the home. Similar in principle to HMIs, electric current causes mercury vapour to emit UV light which is translated into the visible spectrum by the phosphor coating on the tube. Kino Flo pretty much has the monopoly on fluorescent lighting for the film industry. Like HMIs, fluorescents require a ballast.

Pros: reasonable CRI from Kino Flos (appalling CRI from domestic/commercial fixtures), very efficient, get warm but not hot

Cons: limited dimming, high fall-off of light

Colour temperature: 5,500K and 3,200K tubes available

Light quality: soft

 

LED copyLED (view detailed post)

Gradually replacing tungsten as the most common lamps found on no-budget shoots, LED (light emitting diode) units contain semi-conductors that emit light when their electrons reconfigure. The technology is advancing rapidly, but there is currently a wide range of LED lamps on the market, varying greatly in price and corresponding quality.

Pros: extremely efficient, barely get warm, can run off batteries, almost fully dimmable, some models have adjustable colour temperature

Cons: CRI ranges from almost acceptable in the expensive models to downright shocking in the cheaper ones

Colour temperature: varies

Light quality: varies

 

Though there are other types of lighting, like xenon, metal-halide and HEP (high efficiency plasma), the above four are the main ones you will encounter on film and TV sets today. Over the next few weeks I’ll look at each of those types in more detail, listing many of the specific units available in each category and their applications.

By the way, if your budget is too tight to hire film lamps of any kind, you may want to check out my post on lighting without movie lamps.

Know Your Lamps: Overview

Looking Back: “Daemos Rising”

Who is that handsome young chap?Last month saw the re-release of Reeltime Pictures‘ Daemos Rising, an unofficial Doctor Who spin-off film I photographed way back in 2003. It’s lovely to know that the film is popular enough for a high street release after so much time, and watching it again brought back many memories. Let the sharing of these memories commence…

2003 was Doctor Who’s 40th anniversary year, but the show had been off the air for over a decade and many fans, myself included, thought it would never return. In September I was weeks away from the start of principal photography on my second (and last) no-budget feature, Soul Searcher, but I was delighted to take a break from the stresses of self-producing to DP a tribute to the show I’d grown up with. “You won’t hear anything more from me now for a week,” I announced on my Soul Searcher blog on September 16th, “for I shall be ensconced in a cottage in a woodland area of Dorset (or possibly Devon – they’re easily confused), shooting a Doctor Who spin-off film for Reeltime Pictures. As you do.”

Screen Shot 2016-08-13 at 14.59.00The location was in fact in Devon: the home of Ian Richardson, who has since sadly passed away. (Ian had an illustrious stage and screen career, including the lead role in the original UK version of House of Cards.) Although Ian’s involvement would be limited to a voiceover, his son Miles Richardson played the role of Douglas Cavendish, an ex-UNIT operative troubled by a time-travelling ghost, a creepy moving statue and of course the Daemons. For those non-Whoovers amongst you, the Daemons are a devilish alien race featured in a classic Third Doctor serial. Reaching its tentacles deep into the expanded Who-niverse, Daemos Rising was also a sequel to a prior Reeltime production, Downtime, and was tied in to a spin-off book series.

Screen Shot 2016-08-13 at 15.16.32It was Miles who recommended me to director Keith Barnfather, having worked with me earlier that year on a feature called Blood Relative. Miles was joined on screen by his wife Beverley Cressman, playing Brigadier Lethbridge-Stewart’s daughter Kate. Rounding out the cast of three, as the aforementioned spectre, was Andrew Wisher, whose father Michael was the very first (and arguably best) actor to portray Dalek creator Davros.

The shoot didn’t start well. On the journey down to Devon, the prop shaft (bit that connects the engine to the wheels) dropped out of our rental van on the M5! Luis, the driver miraculously got us onto the hard shoulder while we still had some momentum, and the DVD extras include footage of us recovering as we awaited the RAC.

But this brush with death aside, I remember the shoot as a very happy one. It was a small team, just the three actors, Keith, his partner Anastasia, writer David J. Howe and his wife Rosie, and Luis on sound. We all stayed at the cottage, which was lovely, and enjoyed many a home-cooked meal and showbiz yarn. Miles and Andrew even gave an impromptu rendition of Billy Joel’s a cappella classic The Longest Time at one point.

Screen Shot 2016-08-13 at 14.57.17

It was the era of Mini-DV, so I was shooting on my Canon XL1-S in glorious 576i. (I remember the damp playing havoc with the DV tapes when we shot the third act in a cave system called Kent’s Cavern.) I also supplied the lighting package, which consisted of 2 x 800W Arrilites, 2 x 1000W Arrilites and a vintage 5K Mole Richardson fresnel. The latter required a local electrician to wire us a 32A socket into Ian’s fusebox! Back then I used only hard light because I didn’t know any better, and it gave everything a distinctive noir style.

Screen Shot 2016-08-13 at 15.15.26 (2)Speaking of a distinctive style, Daemos Rising is a significant milestone in my career because it was the first time I ever used smoke. The script called for spooky mist in several scenes, so Keith bought a Magnum 550 and we ended up using it on all the night exteriors. He kindly gifted me the machine at the end of the shoot, and needless to say I never looked back. Many a cast and crew may think of their poor lungs and rue the day that Keith Barnfather gave Neil Oseman his first smoke machine!

While the day interior lighting looks rough to me now, I think many of the night scenes still look pretty good 13 years on. Although my lamps were all tungsten, and the XL1 didn’t allow me to dial in a white balance, I would point the camera at something red and force the camera to white-balance on that, turning everything a nice James Cameron cyan.

Screen Shot 2016-08-13 at 15.01.20Just days after we wrapped, the BBC announced that Doctor Who would return in 2005. I fear the new generation of kids who now form the core of Who’s avid audience might find Daemos Rising a little slow and talky, but for fans of the classic series there is lots to enjoy. The tone and storyline are very Who, and there are several easter eggs scattered throughout the film. And some aspects of Daemos Rising fit the new series’ continuity too, including the Brigadier’s daughter Kate — now played by Jemma Redgrave – and UNIT’s Black Archive.

The re-release provides the opportunity to watch Daemos Rising in the aspect ratio we originally intended, 16:9 (the original DVD having been masked only to 14:9) and also offers the option of 5.1 surround sound. It’s available now from Amazon and high street retailers.
