Photograph for separation
Use clear light and enough contrast between product and surroundings. Avoid clipping the product edge out of frame; include breathing room around it.
Create and inspect a cutout
Remove the background and save as PNG. Zoom in around straps, glass, dark edges, and soft shadows. An automatic cutout may simplify fine details or remove subtle parts of a product.
Place on a background and verify
Test the transparent asset on the intended store background and check the crop at the final size. Confirm the current marketplace image rules before publishing.
