Call me crazy but I'm considering doing some KAP on 35mm film. Though not anytime soon. Only after Ive had sufficient practise using old, second hand digital point and shoot cameras from kites. The reason I'm considering that rather ancient option is to make use of the dynamic range (using negative film.) The only time Ive previously done aerial photography was with a GoPro camera and I wasn't overly impressed with the results. For one thing, the camera was shooting on auto exposure which didn't help (no choice in the matter really.) And bright areas in the landscape below were blown out. Not a nice look.
Ive got a few old, manual Canon 35mm SLRs which I used to use years ago on a regular basis. One of them is a Canon T70 which advances the film automatically. Obviously, I wouldn't use an intervalometer with it for KAP as that would chew up film in no time. Would there be any way of firing such a camera remotely? I'd probably have to shoot a whole roll of film on one subject / location, firing shots from different positions.
