The story of the Tank Man photo by its photographer
Of his failing flash, and lens situation: I could just imagine Robert Capa and Larry Burroughs chuckling down from heaven over a couple of cold beers.Let's remember Capa's most famous shots of D day landings were botched by incompetent developing and only a few frames were usable. (I think somebody else blew the developing, not Capa but I'm not 100% sure)
