My old man always used to take his old Leica to the airshows and got some cracking pics on slide, was always exciting to have a look a few days later to see how many good ones he got, reminds me, he always used to shake his head after taking the shot saying, "no, no that won't come out well" and then on getting the slides back we discovered that it came out perfectly!
A real science to taking pictures with that old thing, would have to take light readings and set up for the shot in advance, no automation there!
Only thing was the place in South Africa where we would get some prints made never got them near as good as the studios over here in the UK.
Oh the memories!
