I hope this is the right place to post this question. I have not had to take film through airport x-ray machines for a number of years but now will be undertaking a trip that will require passing through the machines a total of six times. The film stock will primarily be 400 ASA Fuji colour neg and 100 ASA colour neg. Am I likely to have problems with fogging etc? Any tips, advice, precautions I should take etc? Thanks for your help.
