What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: plain light background without textures or noticeable gradients.
- Head tilt. Straightened if the head leans slightly to one side.
- Frame. Exactly 51 × 51 mm, by the document’s rules.
- A light shadow on one side of the face. Gently brightened.
- File and print sheet. A file to the document’s rules and a 10 × 15 or A4 sheet to print.
What can't be fixed for free, AI correction fixes
- Hard shadows and uneven light on the face.
- A smile, raised brows or a half-open mouth. Cropping keeps the face it was given.
- Too few pixels. If the original is smaller than 602 × 602 px, enlarging it only blurs the face.
- Clothing and pose. Shoulders out of frame, body turned away from the camera.
Glare on the lenses. Take the glasses off or turn away from the light source and shoot again.
