Use soft, even light
Hard overhead light creates deep shadows and bright reflections. Start with indirect window light or another diffused light source. If the product is reflective, move the light source farther away or soften it rather than trying to fix every hotspot in editing.
Avoid mixing very different light colors when possible. Warm room lighting mixed with cool daylight can make a product look different from one side to the other.
Give the product room
Do not frame so tightly that the item touches every edge of the photo. Cross-listing becomes much easier when there is enough breathing room for square, portrait, and wider destination canvases. Extra clean background gives an image tool room to resize or crop without cutting into the product.
Simplify the background
You do not need a professional sweep. A clean wall, poster board, tabletop, or uncluttered area can be enough. The goal is to keep the buyer's attention on the item and make its edges easy to distinguish. Background cleanup tools work better later when the original scene is not visually chaotic.
Shoot the buyer's questions
Think beyond the hero shot. Photograph front, back, sides, labels, model numbers, included accessories, texture, wear, and any defect you would want to know about before buying. A technically perfect photo is not useful if it hides the information a buyer needs.
Keep the camera consistent
Clean the phone lens before shooting. Hold the camera roughly level with the product, especially for boxes and electronics where perspective distortion can make straight edges look awkward. If your phone offers a grid, it can help keep the main item centered and level.
Edit for clarity, not fiction
Brightness, contrast, white balance, and modest sharpening can make a photo easier to read. Avoid edits that materially change the color, condition, texture, or appearance of the item. A listing image should help a buyer understand the product, not make the product look like something else.
Preserve the originals
Do your marketplace resizing and compression on copies. If you later decide that one platform needs a different crop or higher resolution, you can regenerate from the master instead of trying to reverse an old edit.
