well, i believe is in this mth's photoi. was it john cosgrove who said, quite emphatically i might add, "its official. x-ray machines do damage film." or something like dat. :think: another pro also told me in dec when we met, dat he always puts his film in a protective bag and hand-carry them. the higher the ISO, the easier for it to be damaged by x-rays.
think u can get these bags from either ruby or CP. i think CP hanged them on their metal racks along the wall.
