Just awaiting delivery of a 70mm back, brings me the subtle quandry of how to develop the film. Can anyone suggest how I could modify or fabricate a plastic reel, or indeed a lasagne type reel for this. Trying the smaller format approach first (have an aerial camera that takes 5" rolls that I'd like to use - thinking that the lasagne / film apron approach may be best). What would be the best material to use and how best could I make the dimples to ensure the whole film gets developed?
Hopefully if the 70mm proves successful, then creating such a reel for the larger 5" roll should be a matter of scaling it up - last I looked I think it was Agfa who still makes aero film in 5" rolls. . .
