Personalausweis Hologramm erkennbar auf Fotos?
Ich musste vor kurzem Bilder von meinem Perso hochladen, aber durfte einiges schwärzen. Ich habe aber erst spät bemerkt, dass es ja auch die Hologramme auf den Persos gibt und nun wollte ich wissen, ob man die Hologramme auf den Fotos erkennen kann oder nicht. Mit bloßen Augen habe ich nichts bemerkt, aber gibt es Möglichkeiten, dass man sie trotzdem noch erkennbar gemacht werden z.B. mit irgendwelchen Bildbearbeitungsprogrammen?

if you place a perso on a scanner, i.e. the image acquisition takes place exactly at the right angle, then you can recognize the holograms.
otherwise it comes to the light incidence angle.
I photographed them normally with the handy and you can’t see anything. Or what do you mean?
but that’s exactly what I mean. it depends on the image angle or the angle of incidence of light, whether you recognize holograms well, badly or not at all.
jaa I understand, but I should blacken it, so I did it.
the photo of a personal ID is usually used as an identifier or proof of age. If you then blacken the most important elements, you can actually forget it.
otherwise eich wouldn’t know why I should photograph my person. at most as your own “safety skopie” on my pc if I should lose it to indicate the number etc. in the loss message.
I’ve broken the important details. It was originally only possible to recognize my name and birthday on the photo. But on the hologram you can see my face and the number. That’s why it was important to me to know if a hologram is still recognizable or can be made recognizable even if you couldn’t recognize it on the photo.
I don’t understand your problem. the hologram is a strong security feature of the sign to make it fake very difficult if not impossible. that is also just the same picture and a few letterings. Why is it a problem whether or not someone sees it??
ahh okay, because I couldn’t recognize it on the photo, I can assume that in general none of the ones receives the picture can recognize the hologram or? Do I get that right?
The light only has to fall up in the right angle
Then no image processing program can reveal something. A photo/scan is two-dimensional and a hologram works only thanks to three-dimensional visibility under changing light incidence.
