The main image on Amazon is required to have a pure white background and no text or graphics.
While some sellers do get away with graphics for some time, often their listing gets suppressed. From an aesthetic perspective, plain, white background gives a more professional, and much cleaner finish. It also helps colorful products pop up.
Using a photography shooting tent or curved backdrop helps in eliminating the shadows, and cancels the sharp angles that might leave a picture look a little harsh. Our editing team then touches up levels and edits out any blemishes, dust, or smudges for a “better than real life” finished photo.
