I'm traveling to Yurop and was thinking about bringing some old expired rolls with me. Would xrays obliterate them? I also wanted to shoot at least one or two rolls of some fine grain film purchased while I am there. I'll be visiting the alps so I guess lots of bright white and some green. I was thinking Velvia 50 or maybe Provia 100? I have never shot color reversal and have no idea where I could develop those. Some Ektar 100 maybe? It's C-41 so I guess I could take it to any shop? I was thinking some Ilford or Tri-X also, these I know where to take (can't do it myself while I am there, no time).
