What these millimetres work out to
- In a 40 × 50 mm frame a head band of 64–72% is 32–36 mm from the chin to the crown.
- Of the 50 mm of height that leaves 14–18 mm for the gap above the crown and the space below the chin together.
- At 300 dpi that is a head 378–425 pixels tall — below 378 px the file is too small to print, however good the crop is.
- Against the European 35 × 45 mm standard this frame is 1.14 times as wide, 1.11 times as tall and 1.27 times the area — a photo cut for one of the two cannot be reused for the other.

What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: plain white background.
- Head tilt. Straightened if the head leans slightly to one side.
- Frame. Exactly 40 × 50 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 472 × 591 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.
One thing that is specific to Hong Kong
- No head dress; avoid heavy make-up and overly dark or overly light-coloured clothing.
