The one-window setup that does 90% of the work
Put your product on a table next to a large window, at 90° to the camera — light coming from the side, not from behind you and not from behind the product. Side light creates the soft shadows that give a product shape and texture; front light flattens it, backlight silhouettes it. North-facing windows are ideal because the light never turns harsh, but any window works on an overcast day — clouds are nature's softbox.
Then add the $0 tool every studio uses: a white bounce card. A piece of white foam board, printer paper or a cereal box wrapped in white paper, placed on the shadow side of the product, bounces window light back in and lifts the dark side. That single reflector is the difference between "moody amateur" and "clean catalog". Nothing else is mandatory.
Mistake 1: mixed light sources (the orange-blue disaster)
Window light is blue-ish (~5,500K). Your ceiling bulb is orange-ish (~2,700K). Turn both on and your camera can't white-balance either — the product ends up with an orange top and blue shadows, and whites that are never white. It's the most common reason home product photos look "off" in a way sellers can't name. The fix costs nothing: turn off every artificial light and shoot with the window alone. If you must shoot at night, use one lamp only, move it to the side, and diffuse it through a white pillowcase or baking paper.
Mistake 2: direct sun and harsh shadows
Direct midday sun through a window throws hard, black-edged shadows and blows out highlights — brutal on glossy products like cosmetics jars and electronics. If sun is streaming in, tape a white bedsheet or baking paper over the window: instant diffusion, instant softbox. The shadows go from knife-edged to soft gradients, and reflective surfaces stop mirroring the window frame.
Mistake 3: too little light, rescued by ISO
A dim room forces your phone to crank ISO, and high ISO means noise — that grainy, muddy look that survives every filter you throw at it. Phones hide it well on screen and it reappears the moment a marketplace compresses your upload. If the photo looks dark, don't brighten it in editing: move closer to the window, shoot earlier in the day, or prop the product higher so it catches more light. A tripod (or a stack of books) helps more than any app, because a stable phone can use a slower shutter instead of a higher ISO. More phone-specific technique is in our guide to product photos with your phone.
The lightbox question
A $25–40 pop-up lightbox with built-in LEDs is worth it if you sell small items (jewelry, cosmetics, accessories) and shoot often: it gives you the same clean, even light at 11pm as at noon, and a consistent look across your whole catalog — which is what makes a store look professional at a glance (more on that in how to make product photos look professional). It's not worth it for large products or occasional shooting; the window setup wins there.
The 10-second checklist before you press the shutter: ceiling lights off · window at 90° to the camera · bounce card on the shadow side · white balance looks white · product fills most of the frame. If all five check out, the photo will survive zoom.
When the light still isn't right: fix the background, not the photo
Sometimes the shot is sharp but the scene betrays it — yellowish wall, cluttered table, gray "white" background. You can rescue those photos without reshooting: our free white background tool cuts the product out and drops it on pure white in your browser, and the background color changer puts it on any brand color. That fixes the background; it can't fix noise or blur, so nail focus and steadiness first.
The honest shortcut: skip lighting entirely
Here's the part most lighting guides won't say: for standard catalog shots — product on white, product in a lifestyle scene — AI generation now produces the lighting for you. You upload one decent phone photo (any light, any background), and the output comes with studio lighting baked in: soft key light, filled shadows, clean reflections. That's exactly what Mercatus does, and it's why many sellers shoot one reference photo and never build a light setup at all. Learn the window setup for the photos only you can take — condition close-ups for used items, true-color verification — and let AI handle the catalog set.
