Lighting ‘X, Y & Z Rays’ by Revenge of Calculon

Stage-bound music promos can be an interesting challenge for a cinematographer. Often there is no set that has any basis in reality, no windows, no starting point for lighting. This should be very freeing but is actually pretty scary. Where to start?

This is X, Y & Z Rays by Revenge of Calculon, my latest music video for director Tom Walsh of Polymath Pictures

Nick Pylypiuk did an awesome job of building and programming the LED panels, and Amy Nicholson did a great job of dressing the gadgets and cables. How did I go about lighting it?

Well, cinematography isn’t just about mimicking natural light. It’s about depth and contrast, to name just two things. And depth was where I started. If I didn’t want the LEDs to float in a black background, then it was necessary to light the cyclorama to reveal it as a separate layer behind the LED panels. But leaving the cyc dark would give the image more contrast. I wanted to have my cake and eat it. So the lamps I lit the cyc with had to be dimmable so that they could be off at some points during the track and on at others.

I placed 800W tungsten lamps on the floor behind the central and outermost LED panels, uplighting the cyc. Poor Emma, the art assistant and the smallest member of the crew, was assigned to hide behind one of the panels, pulsing the 800s on a dimmer board in time with the music.

Next I needed to light the musicians. We didn’t have access to the studio grid, the LED panels were providing plenty of light from behind, and any light from the front would have polluted the panels, so my only option was to light from the sides. I placed a Dedolite off to each side, gelled with different varieties of blue/green gel to make this layer of the image stand out from the warm, ungelled tungsten of the 800s.

The 4 Dedolites can be seen here, gelled blue-green, blue-green, purple and yellow.

This was all very well, but it left a lot of the art department’s nice foreground dressing in complete darkness. So I set up a second Dedolite on each side, crosslighting the amps and other gubbins. I gelled one of these yellow and the other pinky-purple. Normally I prefer to use a narrower palette of colours, but since the patterns programmed into the LED panels used all the colours of the rainbow, I felt I had license to do the same.

After a couple of run-throughs, I decided on an alternating, pulsing pattern for the four Dedolites at half the speed of the 800s. My initial instinct had been towards something more sophisticated, but there was plenty going on on the LED panels without needing to make the foreground too manic.

Amy was still looking to add to the set dressing, so I suggested putting our battered old Kinoflo into shot for a bit of extra interest. This left only a Kinoflo Divalite and a 1×1′ LED panel in my arsenal. “What the hell,” I thought, and hid them behind a couple of the amps to pick out some more of the set dressing.

Despite all this, I still think the strongest bits of the video are those where all my lights are off, leaving just the patterns on the large LED panels. With a bit of dispersed smoke in the studio, the LEDs give off a lovely glow, and the dynamic wrapping backlight they shed on the performers is really beautiful.

And we quickly found that they looked great out of focus, and went with that for a few set-ups. In fact, much of the single day of shooting was spent experimenting and going with the flow. Tom trusted me to get interesting coverage while he helped operate the LED panels, and I found the electronic music guiding me into Wes Anderson-style camera moves: lateral tracks, and bold, simple pans and tilts.

Lighting ‘X, Y & Z Rays’ by Revenge of Calculon

Hellblazer

A couple of weeks back, I served as director of photography on a music promo for heavy metal band Savage Messiah. Directed by Tom Walsh of Polymath Pictures, the video was released yesterday by Earache Records.

This shoot represented a number of firsts for me: first time operating a Red Epic, first time using a tilt-shift lens, and first time shooting more than 50 frames per second.

Red

While preparing for the shoot, I found this video tutorial from the oddly-named Embassies of Cinema was very helpful in demonstrating the basics of operating the Reds. As Tom said to me, a camera’s a camera, and if you know how to operate one then you can probably find your way around any other, but no-one wants to look like an idiot when they show up on set and start tentatively pressing buttons on an unfamiliar piece of kit.

If there’s one thing I learnt about the Red that I’d like to flag up to other first-time users, it’s the crop factors. The Epic has a Super-35mm sensor, but it only uses all of that sensor when in 5K mode. If you shoot at a lower resolution, the camera simply ignores the outer edges of the sensor, rather than scaling the image to that smaller size,. The result is that your lenses appear to get more telephoto as you decrease the resolution. So watch out for that.

Tilt-shift

A tilt-shift lens is one which allows you to move the lens elements around relative to the focal plane. The shift mechanism is primarily of interest to stills photographers who want to capture skyscrapers without them appearing to taper towards the top. The tilt is the fun part.

Normally, the glass elements in a lens are parallel to the focal plane (the camera’s sensor). Imagine a shot of three apples lined up next to each other on a table. They’re all the same distance away, so when you focus on one, the other two are in focus as well. But if you tilt the lens, only one apple might be in focus, and part of the background might be in focus too. This effect is often used to make cityscapes and landscapes look like miniatures, but it’s also useful for general weirdness. If you can’t afford to buy or hire a tilt-shift lens, a technique called “lens whacking” offers a low-tech alternative.

Highspeed Cinematography

Regarding highspeed photography, the only thing I have to say is, “Eh?” Can anyone out there explain why tungsten lights would flicker when shot at 300fps? Everything I’ve read says that only discharge lighting (HMIs, kinoflos) and very small tungsten bulbs should flicker at high frame rates. Surely the filament in a blonde shouldn’t be cooling enough between peaks in the AC power supply to register a flicker in a 600th of a second? I certainly can’t think of any other explanation.

You can see the flickering at around 2:24 in the video if you’re looking for it, but there’s enough dynamic lighting, smoke, lens flares and tilt-shifting that it all just seems part of the deliberate effect.

Thanks to Tom and designer Amy Nicholson for another great shoot. I look forward to working with them again next week on A Cautionary Tale.
