Kodachrome (2017)

Although three years old already, the film "Kodachrome" has appeared on
Netflix's list (Europe) . I an guessing it will be entertaining watching
for most posters here.

Who has seen/witnessed the photographers' salute - the equivalent of a
21 gun military salute - which is towards the end of the film? It's the
first time I've seen it, and am keen to establish whether it is a bit of
Hollywood fantasy, rather than a real "thing".
