I've been reading the original "One Camera, One Lens, One Year" article, more formally titled "The Leica as Tutor.", and I've been thinking about embarking on a similar project. What I can't figure out is how strictly to apply the rules; I know I'll be breaking the "Leica only" one, probably with a Kodak Retina, but where does it end? I reckon I'll be sticking to HP5 and LC-29, but are push and pull processing in the spirit of the "Challenge?" What about filters (either "contrast" or neutral density)? What about flash, for that matter? I'm not currently set up to wet print, but I'm fairly happy with my - currently multi-format - dev and scan setup. Stretching the rules too far (in particular the one about filters) would probably mean using my Nikon FE instead, which would "dilute" the challenge still further. I realise that in the end these are all personal choices, but if you were embarking on a similar undertaking, where would you "Draw the Line"?
