I think going digital is about getting the images out safely, you can upload via remote satellite feed if need be... To get the images of the afghan girl out, Steve had to hand sew the film into his jacket that he wore through security at the airport.. He sewed the strips into the lining of the jacket in complete darkness remember... Not easy)...
Digital upload is way easier
Do you have a reference for this?
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
