Another thing that struck me last night regarding the documentary that started this thread, the one filmed aboard HMS Splendid in The Gulf. At one point the captain was showing a photo of a Cruise missile being fired and saying it had been published in a newspaper. The picture looked like it was taken through the periscope (it was a circular colour image with black borders) and a crewman was shown editing it on a computer.
Now my thought is, because the submarine is on station so they can't pop down to Quick Snaps or wherever, and it looked like they had a circa 1970's-1980's camera on the persicope housing, presumably they had the ability to develop and digitize their images on board? Does anyone know if that's the case? Ho hum, I'll shut up about it now :-) Chris
