>>4028207>OP cant understand the point of the film and gets wrapped up in an insignificant technicality that was specifically used so normies with only a basic understanding of film photography wouldn't get confused about the underlying theme of using the last shotI have never even heard of this film but I can infer what it's roughly about from the poster and the name.
I'm betting it's about some kind of crisis, possibly a conflict and this guy is a war photographer. He goes about shooting snappy snap snap but then the turning point happens, he gets separated from his squad/team/whatever or they die or something and he has to survive the battlefield on his own and get back to base camp or something or other. At this point, he has 1 exposure left and he goes through a whole bunch of psychological trauma and sees terrible war crimes along the way and is tempted to shoot them, but knows possibly the worst is yet to come and so has to pass up on amazing shots. By the end of the film, he realizes holding out for some immortalizing shot that's never going to happen is stupid and that he babied his last exposure and takes a random selfie finally out of the war torn city or maybe of a kid running along or something that ultimately doesn't matter, but it means more to him than anyone else who'll see it.
Clicking on the pic I see the tagline is The end is here, so I guess Im wrong and its some apocalypse film then.
