I'd like to shoot some color again in my medium format rangefinders. I've been shooting black and white ISO 400 which I believe is the best all around ISO for hand held rangefinder stuff. Anyway, I know about Provia 400, but I think I might be able to get away with ISO 200. So it's either shoot Kodak E200 or shoot Velvia 100 or Provia 100 pushed to EI 200. Which would yield better results? I prefer the look of Velvia and Provia, but am not familiar with them when pushed one stop. Is either film as good at EI 200? One better than the other when pushed? And how would either hold up grain-wise to Ektachrome 200? Thanks alot!
