Yesterday I had to visit a photographer to take a picture of me to update my identity card. Until now, I always avoided getting new documents, because the rules for the photos have been changed since 2005. I decided to get the new "digital recognizable style", because this one is required for the passport (so maybe I could reuse the picture some years later). Interestingly, besides technical sound pictures, regarding sharpness, contrast, lighting, background, and print quality, also the person in front of the camera has to fulfill some requirements. In particular, you have to

1. Look with a neutral face into the camera (without open mouth and any non-aligned angle of your head)
2. Look straight into the camera (no closed eyes, no hair in front of your face, don't squint)
3. The eyes have to be visible (e.g. no dark glasses, shadows, etc.)
4. You're not allowed to wear anything on your head (except for religious wear)

Afterwards, the photographer has to crop your picture to show almost only your face (e.g. hair cut of). My photographer told me that he once had to take pictures of a man with a rounded face and jug ears. Unfortunately, the tailored software software he was using (certified of course), told him to crop his ears!

As a result, a computer system might have the change of detecting your identity with a failure rate of about 3/10. For any other kind of resource (e.g. official, policeman), it might be a bit harder. However, since my photo is now officially registered, I can freely provide it to the remaining people as well:

I already ran an edge detection filter, giving you the information required to recognize me. Have a nice day!
