Just got back from visiting family in San Diego, California, and while I was down there (I live in Idaho) I bought some rolls of Ilford film at George's Camera Shop in Clairemont. Since we were scheduled to fly back home, the purchase raised the issue of TSA security scanners fogging the film. I did some reading on the web before-hand, but found mostly contradictory advice. The sales guy at George's told me when he's faced with a similar situation, he unboxes the rolls, puts them in a ziplock bag, and hands them to the nearest TSA agent with the request that they be hand-inspected. I followed his advice but I was uncertain if I should take the rolls of 120 film out of their foil wrappers. Finally I took them out of their boxes and shoved them in a ziplock, still wrapped in foil. To make a not very long story short, all came out well. Few people traveled with film any more, I reasoned, but even though I was uncertain how TSA would react, advisory signs mentioned the potential liabilities of scanning unprocessed film. The agent I accosted seemed a little uncertain about how to proceed but he finally opened the bag, fingered the rolls, and handed them back to me without insisting on scanning them. I'll find out in a few days how the film fared when I do some shooting.
