PassportPic: ID Photo Maker

Version 1.4 adds explainable lighting and sharpness guidance to the U.S. visa JPEG workflow. When exactly one face is detected, the app looks for severe underexposure, washed-out highlights, and possible blur or softness in that sampled face area, then explains how to improve the capture. Otherwise, subject-quality rows remain cautions instead of showing a pass. These checks run locally and are warning-only: they do not alter the photo, make an acceptance decision, or replace manual review of current official instructions. The existing one-face, position, scale, background, final-byte, format, color, and file-size checks remain available. U.S. and Canadian online-renewal original workflows still preserve and verify exact imported bytes; the Canada commercial-photographer checker, U.S. 2x2 print sheet, and visible SHA-256 proof remain unchanged.
