I'm going to be shooting some 4x5 color in the near future and could use a little input. It's been years since I've shot color and the films have all changed (except that Ektachrome is still listed. Does it still have a bluish tinge to it?) In perusing Freestyle's website, they list three different Fuji transparancy films. Provia, Astia and Velvia. Is there anywhere that I can get comparitive information on these films? I'll be shooting outdoors. What is the general preference?
