Passport crops fail when they look right but violate exact rules
`passport-crop-guides` is compliance-first, not style-first. Most standards specify head-size range, eye-line position, top margin, background uniformity, and lighting constraints. A centered face preview can still be rejected if pixel dimensions or print conversion are off. Another frequent failure is beauty filtering before crop: softened edges, missing ear contours, and artificial skin smoothing can trigger machine checks. Cross-country rules differ: some accept light gray backgrounds, others require strict white; some tolerate slight smiles, others require neutral expression. For bulk processing, keep three tiers per person: original, cropped master, submission derivative, to trace whether rejection came from capture, crop, or export. If the same image is reused across admit cards, badges, and forms, standardize the first approved template to avoid inconsistent head ratios across systems.
Passport crop workflow
- On `passport-crop-guides`, choose the exact authority standard before cropping.
- Verify head ratio, eye line, top margin, background uniformity, and edge clarity.
- Keep original plus submission derivative with export parameters for audits.
