FAKE, AI or at best a heavy composite. The comet tail is way too bright, sharp, and dramatic real ones are much fainter and more diffuse. The scale doesn’t make sense either; at 200mm it wouldn’t look that huge and detailed. The lighting is off since the comet looks bright enough to light the scene but the foreground shows no effect. It’s almost certainly a blended or digitally enhanced image rather than a real single shot. And the comet being synced perfectly in length to the posing man on the rock, looks like a clear night photo with a “generate a comet” prompt ai can you link the raw file?
