Take the following precautions about photographs for a Schengen visa to avoid rejection
The photograph background should be plain and neutral. It should not be older than the last six months of your visa application. It should be 35-40mm wide with the applicant’s face taking up 70-80% of the frame
It must be printed on high-quality paper without creases or marks on it
The applicant should be looking directly into the camera with both eyes open, hair pulled back and a neutral expression
Both ears and the full face should be clearly visible from the forehead to the chin.
Choose a light frame of spectacles that do not cover your eyes without a tint.
Headgear is allowed only for religious reasons. This headgear should not have any shadows on your face and not cover your forehead or your chin
Children's photographs should not have anyone else in the frame.
