Wow - Imagine the pressure to deliver something... I guess there's no shrugging your shoulders and saying "well 1 keeper from a roll isn't THAT bad"
I'm currently on my last roll of Kodachrome, and it's been tying up my best camera for the last 2 months! It's been the most considered set of shooting I've ever done, and I just KNOW that they're all going to be dissapointing - probably because I've built them up in my head. Worst of all - my scanner doesn't like Kodachrome, so even if they DO come out something like, nobody here will get to see - they're destined for the projector only.
