What makes a photo "biometric"?
A biometric photo is specifically designed for machine-readable identification. Unlike a casual portrait, it follows strict rules about facial proportions, head position, expression, and background so that facial recognition algorithms can accurately match it against databases.
Key requirements that distinguish biometric photos:
- Face occupies 70โ80% of the frame height
- Eyes are at a specific height in the image (typically one-third from the top)
- Neutral expression with mouth closed
- Both ears visible
- Uniform, light-coloured background
- No accessories obscuring the face
