One Light. Infinite Depth. How a Single Large Source Can Define Your Style in Product Photography.
One Light. Endless Depth. How One Big Source Can Set the Tone for Your Product Photography
I help photographers and creative entrepreneurs over 40 reclaim their confidence, cut through the noise, and build bold, independent lives through no-BS insight, experience, and action. Welcome to my Substack.
I am glad you are here.
Most photographers add lights the way some cooks add ingredients: when something seems off, just add more. A second strobe here, a fill card there, and a hair light because someone on YouTube said so. The result is often correct from a technical point of view but not necessarily memorable.
Large light sources have made some of the most iconic work we have. One window. One softbox.
Here are ten rules that can help you see things in a new way when it comes to what one light can do. (Photos by the students in the last “One Big Beautiful Light” class.)
1. The subject is often defined by the shadow.
Too often, the inexperienced photographer wants to eliminate shadows. Shadows seem like errors. In product photography, though, shadows are what make an object look heavy, three-dimensional, and real. Irving Penn fully understood this. His still lifes used directional light to make shadows pool around objects on purpose, which made a simple glass or a folded piece of fabric look huge.
Before you grab another light, think about whether the shadow in front of you is telling you more about the subject than a light could.
2. The distance changes the quality of the light
A big softbox one foot away from your subject wraps light around curves and hides sharp edges. If you move that same softbox six feet back, the light will be more directed, the shadows will be sharper, and the mood will change.
This is not a technical note. You can change this creative variable. Photographers who work with a single big source learn to adjust its angle and how it moves, just like a painter changes the pressure of their brush.
3. The edge of the light is where the character lives
The most even and flattering light comes from the middle of a big softbox. The edge makes something more interesting: a light that brushes against surfaces, catches texture, and makes gradients that feel almost like they’re in the air.
Put your subject in the inner or outer third of your light source rather than right in the middle. You can tell right away what the difference is with a shot of ceramic, glass, or rough linen.
4. A strobe light can’t teach you what window light can.
The quality changes from morning to afternoon, from cloudy to sunny. On a cloudy day, shooting product work next to a north-facing window gives you a diffuse, steady light source that is very close to a big studio softbox but is hard to make.
Tim Walker’s early atmospheric work was mostly based on light that was already there or close to it. Before you set up a strobe, spend some time with a window to get a better idea of how light really works.
5. The distance of the background affects mood more than the color of the background.
Put your product two feet from a white background, and the light will make that background a soft gray. If you move the product four feet away, the background gets even darker.
This is not after-the-fact in post.
This is science.
This is the ISL.
You can change the whole tonal range of your image with just one light source by changing one spatial relationship.
6. Reflective surfaces are a second light you don’t have to buy.
A white foam board opposite your light source bounces fill back into your subject. A silver board intensifies it. A black board subtracts light, deepening shadows on that side. This is not cheating; the reflector has no power source. It only redirects what your single source already created.
Learning to use a V-flat or a simple foam board transforms one light into a system you control entirely by hand.
7. Height changes the story of an object.
Light that comes from directly beside a product reads as natural and even. Light that drops from 45 degrees above creates a sense of classical formality. Light that rakes almost horizontally across a surface turns texture into grand theater.
Every time you reposition the height of a single large source, you are making a statement about the object itself. A perfume bottle lit from high and slightly behind may read as aspirational. The same bottle, lit low and from the side, may look intimate, almost secretive.
8. Negative space earns its meaning from light placement.
In product and still life work, empty space around an object is not wasted frame. It’s where the light fades, where attention settles, where a viewer’s eye rests. A single large source positioned to light one side of the frame and let the other fall off naturally creates images with a tonal weight that symmetrical lighting never produces.
Look at the still life work of Jan Groover, who used kitchen objects and soft, directional light to make photographs that feel closer to Dutch Golden Age painting than commercial product work.
9. Color temperature can be a creative choice, not a white balance problem.
A large tungsten source, or a strobe gelled warm, changes the entire emotional register of a product shot. Cool daylight reads as clinical, precise, modern. Warm tungsten reads as handmade, intimate, analog.
This is not about correcting for accuracy. Many of the most memorable product images in print advertising from the 1970s and 1980s lean into the warmth of their light sources rather than neutralizing it.
Before automatically shifting to 5500K, consider what the color of the light is already saying.
10. Committing to one light forces better composition.
What happens when you can’t add a second light to solve a problem?
You have to solve the problem with positioning, with distance, with reflectors, with what you choose to include in the frame. Photographers who work with a single large source for a while will tell you they start seeing light differently.
The constraint builds a visual instinct that gear alone cannot.
Don’t think of a single large light as a limitation.
It’s more of a discipline.
The photographers who have produced the most recognizable bodies of work in still life and product photography were not the ones with the most expensive or esoteric gear.
They understood, deeply, what a single source of light could and could not do, and built their entire visual language around that understanding.
Start there.
Move the light.
Watch what changes.
My next One Big Beautiful Light Workshop will begin on April 25, 2026. More information here. Limited to 8 students, and it fills fast. Get the details here.
If you’re over 40 and still hungry to make, build, and create, stick around. This space is for people who aren’t done yet (and never will be). I’ve got five decades of wins, failures, comebacks, and creative battles under my belt, and I’m sharing everything that still works—and burning the rest.
No fluff.
No hustle porn.
Just real tools for building a creative life on your own damn terms.
