User Photo Guidance


To generate the best possible didimo from a photo, our recommendations are:

  • Good lighting conditions - uniform, no shadows across face, no strong directional light (might "burn" areas of your face)
  • Remove hair from the front of your face. If you have long hair, it is better to tie it (or wear it up) so it does not cover your front, ears and shoulders.
  • Remove glasses or accessories - if you are using them.
  • Make a neutral facial expression - no smile or showing your teeth.


When integrating with our API send a photo in a JPEG file with EXIF information - this is the preferred input.

We are looking especially for the 35mm equivalent focal length (exif:FocalLengthIn35mmFilm)
