Please see the attached image. All frames on this roll and another roll have this S shape fogging pattern. The reason as explained by my lab and Kodak is that they were damaged by X-Ray, and I tend to agree. But how they were affected is a mystery. Let me tell my story about the trip: I went to NE US/Canada during Oct 2003. I flew from Hong Kong to San Francisco then to Boston, where I started my trip by a rental car. The land trip (no air in between) was from Boston to Maine, Quebec, Ontario, New York State, Vermont and back to Boston, where I repeated the same air trips but in opposite direction to go back home. I put all my film (40 rolls Veliva 100F and 15 rolls Kodak Gold 200) inside 2 X-ray proof bags. I didn't ask for hand inspection during my air trips. On road everyday I took several new rolls from the X- ray proof bags into my camera bag which followed me everywhere. At the same time I put back used rolls into the X-ray proof bag. Of the 55 rolls only 2 rolls of Kodak Gold 200 were affected. The strange thing is that these 2 rolls were taken in consecutive order around Mount Tremblant area in Quebec. The first roll was already in my Ricoh GR-1 when I arrived at the Mt Tremblant Village. I then took a cable car up to the peak. At the peak I changed to the second roll. After went down by cable car and before I left the village for Ottawa, I changed to the third roll. The first and second roll were damaged as shown in my attachment. If they were damaged by airport X-ray then why the others are intact? Is it just a coincident that the damaged rolls were taken in order? Is there something on Mt Tremblant that may casue the damage? But I had also taken many Veliva slides using my EOS 3 there and had changed rolls, and all slides are OK. Can you think of any possible reason? Thanks for reading my long story.
