The Palette That Exposed a Gap in My Thinking

A few weeks ago I was shooting a skincare line for a small beauty brand. Simple brief, tight timeline, modest budget. One of the products was a pressed powder palette, the kind with a glossy plastic shell and a mirrored interior. I lit it the way I usually light small products: a large softbox camera-left, a fill card opposite, done. The images came back looking muddy. The highlights were uneven, the surface looked cheap, and every seam in my studio ceiling was sitting right there in the reflection like I’d invited it.

I’ve been shooting commercial work long enough that I keep a lighting journal. Sketches, notes, what worked and what didn’t. That palette got its own page with a question mark. Then I watched this tutorial and the question mark turned into a diagram.

Glossy Surfaces Behave Exactly Like Mirrors

In this Visual Education tutorial, Robert Kessler works through a makeup palette and uses it to demonstrate something most photographers understand loosely but rarely apply with precision: a glossy product doesn’t just receive light, it reflects a specific part of your environment back toward the camera. The angle of incidence equals the angle of reflection. Every time.

This sounds like basic physics, and it is. But the practical implication is more demanding than most people treat it. You are not lighting the object. You are controlling what the object shows the camera. Those are different jobs, and conflating them is exactly what made my palette shots look amateur.

If you imagine the product surface as a mirror and mentally trace a line from the camera to the surface and then out the other side, you’ll land on whatever is currently reflecting into your lens. In a typical studio setup, that’s often a dark wall, an uneven ceiling, or the shadow side of your softbox. None of those are what you want.

Building a Gradient, Not Just a Light Source

Kessler’s solution is to build a controlled gradient across the reflective surface rather than placing a light and hoping it falls well. He uses a large white card or foam board positioned above and in front of the product, angled so the camera sees a smooth transition from bright to slightly less bright across the face of the palette.

The key is that the gradient has to be intentional. He’s not bouncing light randomly off a ceiling and calling it soft. He’s tracing exactly where the reflection will land on the product and placing a reflective surface, whether that’s a card, a panel, or a ceiling bounce, at the precise angle that puts clean, even light where he needs it.

The ceiling bounce technique he demonstrates is particularly useful in a small space. By aiming his key light upward at a white ceiling, he creates a very large, soft source overhead. But the placement of that source relative to the product determines what the product’s glossy shell actually reflects. A few inches of difference in where the light hits the ceiling changes the reflection geometry completely. He tests each position by checking the live view and watching how the highlight moves across the surface.

One specific thing worth noting: Kessler keeps his light-to-product distance deliberate. Closer creates a more compressed gradient with a sharper falloff. Pulling the source back spreads the gradient and softens the transition. For a palette with a large flat face, he favors the longer distance so the highlight doesn’t clip to white in the center while the edges go gray.

Where I’d Push This Further

The technique works precisely as described for flat or near-flat glossy surfaces. Where I’d add a layer is with products that have compound curves, things like perfume bottles, lip gloss tubes, or the rounded edges of a compact. Curved surfaces reflect a wider field of view, which means they’re pulling in more of the studio environment at once.

For those, I’ll sometimes build what I think of as a white tent on two or three sides, not a full light tent but a partial enclosure of white cards that guarantees the product is surrounded by clean surfaces no matter what angle the curve reflects toward the camera. It’s an extension of what Kessler is doing, just accounting for the wider reflection angle. The tradeoff is that too much white surroundings can flatten the image entirely, so you need at least one edge where a slightly darker card creates separation and gives the product some shape.

The Fried Egg Test Is a Real Diagnostic

Kessler ends the tutorial with a challenge that I think is genuinely useful: photograph a fried egg. The white is overexposure-sensitive, and the yolk acts as a convex mirror that will immediately show you every flaw in your light. Harsh spots, uneven gradients, stray reflections from a light stand or a wall, all of it shows up on that yolk surface.

I’ve started keeping this in mind not just as a test but as a mindset. If I can mentally model the yolk as a diagnostic surface, I can ask the same question about any product before I fire a single frame. What is this surface going to show the camera? If I can answer that, I can fix it before I shoot.

The single most important thing I took from this tutorial is that professional product photography is an act of environmental control, not just light placement. Watch the full video to see Kessler demonstrate the reflection geometry in real time, because seeing the highlight shift as he repositions the source makes the physics click in a way that a diagram alone doesn’t.
