Background and contrast — USA requirements

[Henry Jensen]

Which background colors and contrast levels does a passport photo online for USA accept, and how can I eliminate shadows or gradients behind the head so automated checks and human reviewers clear the image on the first submission?

USA requires a plain white or off-white background with even tone and no patterns or shadows. Keep strong subject–background contrast and smooth lighting. Clean the background and confirm compliance instantly at passport-photos.net/
