Automatic framing estimates head size; verify crown, chin, margins and the authority’s current rules manually. No acceptance guarantee.

Use a photo taken against a real white wall. Background removal/compositing or retouching may make the photo unacceptable. Use crop, size and print only: background replacement OFF, retouch 0, lighting/brightness/contrast off.
