I can't comment on the risks at any given airport, other than that it's a real concern. I would never consider shooting this amount of film without processing it as I went. The image quality will be better if it doesn't sit around, and you'll know about any equipment problems right then and there. If you don't like some results, you can go back and reshoot. You certainly don't have to print it, and there shouldn't be much problem bringing a few packages of chemistry and tanks with you.(posted 8757 days ago)
