Shoot for the edge
Place the item where its outside edge is easy to distinguish. Indirect window light is usually more helpful than a hard overhead light because it reduces deep shadows and specular hotspots. Move the item away from the wall so its shadow does not merge with the silhouette.
Avoid matching colors: a cream object against a cream wall gives foreground segmentation less evidence. A temporary contrasting sheet behind the item can improve the cutout even though that background will be removed.
Leave enough room
Do not let the product touch the frame unless the final composition deliberately crops it. Extra space gives the mask a complete boundary and lets you reposition with a square or portrait crop later. Photograph thin handles, chair legs, cables, and straps from an angle that keeps gaps visible.
Turn the cutout white
- Select the product photo and review the automatic result.
- Use Erase to remove leftover floor or shadow regions.
- Use Restore around thin parts the initial mask missed.
- Open Background and choose White.
- Choose a crop that matches the destination. Square is common for marketplace thumbnails; 4:5 uses more vertical screen area in many feeds.
- Export JPEG for a smaller flattened file or PNG when your workflow requests it.
Check the marketplace rules
“White background” can mean a visual preference or a technical requirement. Review the current rules for the destination before exporting. Note required pixel dimensions, aspect ratio, padding, color, allowed props, and whether shadows are permitted.
Inspect at two sizes
Zoom in to inspect edges, then zoom out until the image is close to a real thumbnail. Small halos that feel noticeable during refinement may disappear at listing size; a missing handle or uneven crop remains obvious. Optimize for the place the customer will actually see the image.
