RE: new at arial photos
Digital is probably the best. I now use Mustek GSmart3 which is ok,but my first setup using a cheap autofocus cam wih motor and blitz really gave the best result. It was heavy compared to the Mustek,but worked with any 40 size trainer. Disadvantage is that you have to get the film developed and you only get paper pictures....but the quality was much better than the Mustek (and cheaper). I still have that setup lying around, but it will probably never get airborne again.
Aiptek or Mustek is probably the way to go. Good luck!
