Still vs Film

Same scene, from THE AVENGER (War of the Trojans) starring Steve Reeves, totally different outlook between still and what we see in the film. When I saw the image above at Pasquale's Facebook page I went "Hmm...what film is this? From WAR OF THE TROJANS but I don't remember the belt and costumes..." So I checked the actual film and was surprised by the amount of information that's in the still versus what we see in the film. This always makes me irate as why put so much effort in the details but then shoot everything in a long shot? It probably looked bigger on a cinema screen and could see more things but even so the amount of info in the B&W still is superior to the completed film.
