Protecting film while traveling
Later this year I have a great opportunity to visit 2 national parks for a once in a lifetime trip. I'll be staying in 2 separate vacation homes for this photo excursion. Needless to say, I want to make the most out of it. Currently, I have a Nikon D7000 as well as 3 professional lenses.
However, for this trip, I am planning on shooting with a medium format camera using Fuji Velvia 50 as well as some outdated but well stored Kodak Technical Pan B&W film. I am sure this has been addressed before but I do not want to ruin this once in a lifetime event. Heck, I bought a medium format outfit specifically for this trip!
Therefore I'd like to know: Can I go through security x-rays at the airport without harming these films? What procedures / precautions should I take? Is mailing the film to and from my destination a viable or better option? If mailing is a better option, is one carrier better than another (USPS vs. UPS vs. FedEx) for the handling of film?
All input is greatly appreciated!
