How to Film the Moon with Shane Hurlbut, ASC
Recreating realistic, cinematic moonlight is one of the greatest challenges a cinematographer faces. Go too bright, and it looks like daytime. Go too blue, and it feels artificial and “Hollywood.” Make the source too soft, and you lose the sharp, defining shadows that moonlight naturally creates.
In the Filmmakers Academy course How to Master Moonlight: Greatest Game, Shane Hurlbut, ASC takes you behind the scenes to demystify the process of lighting the night. In this specific excerpt, Shane breaks down his minimalist approach to achieving a beautiful, steely gray-blue moonlight using tungsten fixtures, hard shadows, and precise color temperature control.

Here is how you can recreate this iconic moonlight look on your next project.
1. Choose Tungsten Over HMI
When creating moonlight, many filmmakers automatically reach for an HMI fixture because its native daylight color temperature (5600K) naturally reads as blue on a camera balanced for tungsten. However, Shane prefers a different approach.
“The reason I like tungsten light is it’s a much softer moonlight source,” Shane explains.
While HMI lights can feel clinical and excessively harsh, tungsten provides a cleaner, more organic base to work from. By starting with a tungsten fixture, you have granular control over exactly how much blue you want to introduce into the scene, avoiding the synthetic look that plagues many night exteriors and interiors.
2. The “Bare Bulb” Trick for Hard Shadows
The moon is essentially a point source of light in the night sky. Because it is so far away, the shadows it casts on Earth are incredibly hard and sharp. To replicate this characteristic, you need a hard light source.
Shane’s trick is simple but highly effective: Remove the Fresnel lens from the fixture.
For this setup, Shane utilizes a 650-watt tungsten fixture (with a 1K ready on standby in case he needs more punch). By removing the glass Fresnel lens, the fixture becomes an exposed bare bulb. This turns the light into a true point source, resulting in incredibly crisp, hard shadows that perfectly mimic lunar light.
“Look how hard those shadows are. That’s crazy, right?” Shane notes as he sets the primary moonlight source.
| PRO TIP: Always turn off the room’s ambient lights to set and evaluate your moonlight key first. |
3. Creating Texture with Pepper Trees
Moonlight rarely falls perfectly clean into a room; it usually filters through trees, window frames, or architectural elements. To break up the light and add depth to the background, Shane introduces a natural cucoloris (or “cookie”).
He uses a branch from a pepper tree raised in front of the bare-bulb tungsten light. Because the light source has no Fresnel lens to soften the edges, the leaves cast razor-sharp, distinct shadows against the walls and curtains of the set.
“This is how cool these shadows are,” says Shane. “It even projects what’s on the curtain.”
This technique instantly grounds the lighting in reality, giving the audience subconscious environmental cues about the world outside the window.
4. Dialing in the Color: Kelvin and CTB Gels
The hallmark of great cinematic moonlight is the color. You want a steely, cool gray—not a saturated, cartoonish blue. Achieving this requires a delicate dance between your camera’s white balance and your lighting gels.
The Camera Setting:
Shane sets the camera’s color temperature to 2900 Kelvin. If the camera were set to 4700K or 5600K, the 3200K tungsten light would read far too warm (orange). By dropping the camera’s white balance down to 2900K, the 3200K light naturally shifts into a slightly cool, steely range.
The Gel Adjustment:
To push the light just a bit further into the moonlight spectrum, Shane adds Color Temperature Blue (CTB) gel to the fixture.
-
He initially tests a 1/4 CTB gel, but finds it “too blue, not gray enough.”
-
He swaps it for an 1/8 CTB gel. This provides the perfect touch of blue.
“I’m not that DP that uses all this blue and flame green on moonlight sources,” Shane explains. “I think it’s very clean with the tungsten light and the ability to just add a little eighth [CTB].”
5. Bouncing for Room Tone
While your hard moonlight acts as the key or edge light, you still need ambient room tone so your shadows don’t fall into complete blackness.
When bouncing a tungsten light into a matte surface (like unbleached muslin or beadboard) to create this soft ambient fill, the bounce material will naturally absorb some of the cooler tones and warm the light up. To counteract this and match the steely gray-blue of your hard moonlight source, Shane recommends increasing the gel on your bounce source to 1/4 CTB. This compensates for the warmth of the bounce material, keeping your ambient moonlight consistent with your direct moonlight.
