There is a photo of a bullet just leaving the chamber, and the gun in the photo is facing the photographer's lens. This photo was taken by the photographer on the spot.

You can't be sure until you see the real film, but I think the probability of digital synthesis is relatively high, because the risk rate of shooting such works is really too high, and few photographers will take this "life bet" that is almost certain to die; As said on the first floor, it may be taken in front of the mirror, but if so, there should be some reflections in the photo, but I still dare not jump to conclusions until I see what you see.
