I’m preparing for a three weeks stay in Kawagoe (Saitama), Japan and decided the bring the bulk of the film I will be needing with me. It will all be 120 roll film as I will only bring my Pentax 645NII camera and its lenses. I bought three boxes of Fuji Acros 100 for general use, a handful of Fujichrome Velvia 50 for landscapes and a random collection of rolls of Ilford HP5+, Fujichrome Xperia 400 and an expired roll of Fuji Neopan 400. I decided against bringing my favourite ADOX CHS 25 ART as I will be shooting handheld, I will be leaving my sturdy tripod at home as it is just too heavy.
As I will be flying from Heathrow Airport, I checked their Advice for Photographers and they claim anything below ISO 400 is safe in their hand luggage scanners. They do make it clear that film cannot be packed into the hold as those scanners are far more powerful. I knew that already, but it is good they point it out.
I also checked the information on the Narita webpages, the airport for Tokyo, and they claim that film up to ISO 1600 can be brought through the carry-on luggage scanners. I do wonder about that claim in the post-9/11 world and this might be slightly out-dated information.
I have brought 35mm film through customs in my hand luggage before and had it scanned without any issues but it is the first time I bring 120 roll film and I do hope that the people operating the scanners will (still) recognize it as film especially as I intend to bring the plastic containers that ADOX uses for its film to store my exposed rolls and prevent any accidental exposure.
Update: I have now returned from my trip and have not had any problems with the film (up to ISO 400) that I had brought with me and that I put through the handluggage scanners. Good to see that in post 9/11 airports, film can still be brought on the plane without any problems.
