Ok, thanks guys, there's a lot I have to consider. I'm kind of liking the Ektachrome E100VS right now. One thing I'm worried about with that film is the grain. If you look at this picture http://www.flickr.com/photos/rosemania/4299837724/ you can see a lot of grain in the blue sky. Is that the actual film, or is it because it was scanned?
It's nowhere near that grainy. That looks like a consumer 800 or 1600 speed color neg. film. You are also talking about 4x5, so grain is the least of your worries.
