I mainly used Mrs Nutty's discards of n-2. I've killed two of them through road vibration (also killed her car GPS that was in a pannier for "safety and not leave in car" in the same way). On one tour I stopped at Asda and bought a cheapo camera, only to find when I got home that no photos had worked, but I managed to get a refund on that.
My main image capturing is my eyes, my memories, and breathing in the atmosphere of being out. After all, nobody is interested in seeing my photos when I get back.
