OK, I know this has been here a million times but the security is always changing. I'll be flying out of Logan (Major air port in Boston Mass) to Ireland in late April. I just purchased a lot of film for the trip. The film is all black and white (OK, a roll of color slide film too) with ISO ranging from 50-3200. This is a big trip for me and I don't want the film to get ruined. I'll be shooting 35 mm and 120. What would be the best way to present the film at the airport? Shipping it in advance would be difficult because I will be staying some where different every night. I have 50-100 rolls of film. If they insist on it being X-rayed should I still use the 400-3200 film? I'll be traveling with a lot of equipment will this make me seem of less of a threat (opposed to some random person with a lot of random film)? Any advice?
