Shoot a Headshot in a Pitch-Black Planetarium

Gather Your Minimal Gear: The Two-Light Kit

You are not fighting the dark; you are using it. A pitch-black planetarium is a perfect, soundless backdrop studio you don’t have to build. Forget softboxes the size of a car door. You need two small, powerful, and controllable lights. Your key light is a standard 24-inch octagonal softbox. Your second light is a simple snoot—a metal tube that focuses a beam like a flashlight. That’s it. A third stand is useful, but we’ll get to that. Your camera? Any DSLR or mirrorless with a lens between 85mm and 105mm works. Set your ISO to 100, your shutter speed to 1/160th to kill any ambient glow from distant stars, and your aperture around f/5.6. This gives you sharpness from the tip of the nose to the curve of an ear.

Carry gaffer tape. The floor is a maze of cables for the star projector, and tripping one could plunge you into a very different kind of darkness. I once watched a client’s heel catch a black cord, sending a light stand teetering like a felled tree towards a $20,000 projector dome. We caught it, but my heart didn’t settle for an hour.

Place Your Key Light for a Sharp Jawline

Where do you put the main light when there are no walls to bounce it off? You create shape by placing it slightly above and to the side of your subject’s face. Position the softbox about four feet from them, with the bottom of the modifier level with their chin. Angle it down roughly 30 degrees. This does one critical thing: it throws a clean, defining shadow under the jawline and the far cheek. In a normal room, light spills everywhere, softening those edges. Here, the shadow falls away into absolute black, carving the face out of nothing. It’s sculpting with a single tool.

Ask your subject to turn their head slowly toward the light, then away. Watch that shadow. When does it look strong but not sinister? Usually, when the catchlight—that little white reflection of the softbox—sits at the 10 or 2 o’clock position in their iris. That’s your spot. Lock the stand. Tell them, “The shadow is your friend. It’s what makes you look three-dimensional when everything else is flat black.”

Add a Hair Light to Separate from the Void

Now, the magic trick. Your subject is half-sculpted, but their dark hair is melting into the planetarium dome behind them. This is where the snoot comes in. Put it on a stand directly behind them, but pointed back at their head. How far back? About seven feet. Aim the tight circle of light so it grazes the crown of their head and the tops of their shoulders. You are not lighting their face; you are painting a thin, bright outline that separates them from the background. It’s a halo of separation.

The most common error is blasting the light too brightly. You’ll get a glowing, overexposed mushroom cap on their head. Dial the power down until it’s just a subtle, bright edge. Look through your viewfinder. Do they look glued onto the background, or do they pop forward? That thin rim of light makes all the difference. It turns a floating head into a grounded, professional portrait.

My Mistake: The Glowing Collar Incident

I learned this lesson with a CEO client named Martin. We were set up, the lights were perfect, and we were getting great shots. Then I chimp the back of the camera—photographer slang for checking the screen after a shot. I see a faint, ghostly glow around Martin’s white shirt collar. It looks like a soft, radioactive aura. What’s causing it? I’m baffled. The snoot is aimed at his head, not his collar. I walk over and stand where he is, looking back at my setup. And I see it: the intense beam from the snoot was hitting a single, almost invisible, stray thread on his collar. That thread was scattering light like a tiny fiber optic, illuminating the whole fabric. The void behind him acted like a dark canvas, making any spill light glaringly obvious.

I had him change his jacket. Problem solved. Now, I always do a “spill check.” After I set the hair light, I have the subject stand in place and I walk a full circle around them, looking for any errant light hitting their shoulders, ears, or clothes. You fix it by tightening the snoot’s beam or sliding a black flag—a piece of cardboard taped to a stand—between the light and the spill area. One piece of gaffer tape can save a whole shoot.

Review Your Shot for a Polished, Grounded Look

So you’ve taken the shot. What are you checking for on that small screen? First, the eyes. Are they sharp and alive with that catchlight? Second, the shadow line. Does it give definition without looking like a villain’s portrait? Third, the hair light. Is it a clean rim, or is it flaring into the lens? Crouch down and look up at your lens from the subject’s position. Is the snoot visible? If you can see it, it’s probably causing lens flare. Adjust the stand.

Finally, the biggest question: does the person look like they belong in the space, or are they pasted in? The answer is in their expression and posture. A pitch-black environment can feel unnerving. Your job is to keep talking, to give simple directions like “chin down a hair,” or “think of a real smile you had yesterday.” The connection in their eyes is what makes the technical setup feel human. The dark isn’t empty; it’s full of potential. Your two lights and your direction turn that potential into a portrait with gravity, where the person is the only thing that matters.

You walk out with a file that’s clean, ready for a slight contrast bump in editing, and utterly distinctive. No one will know it was a planetarium. They’ll just see a person, defined and clear, emerging from a perfect nothing. That’s the point.

Where this stops short, Capturing the Forest: Lighting Headshots for Nature Photographers picks the thread up.
