Why Passport and Visa Authorities Require White Backgrounds
Government identity and travel documents require clear, shadow-free white backgrounds. When photographs have textured walls, colored backdrops, or poor indoor lighting, automated face scanning systems frequently reject the application with errors like "Unacceptable background contrast".
SizeSnap automatically isolates the candidate portrait, smooths edge hair contours, and composites a solid, uniform pure white background (#FFFFFF) that passes automated consular and exam verification.
