Going up to Maine for the weekend. Foliage should be fairly colorful, and the weather looks like it will be sunny. As noted in the "I just picked up" thread a couple weeks ago, I received several rolls of slide film from a photographer friend, and I'm thinking of using a couple rolls on this trip. Trouble is, I have no real experience with slide film, so a bit of specific advice to supplement my internet research would be helpful.
I have Velvia 50, Velvia 100F, and Ektachrome 100GX. Haven't decided on the camera/lens yet, but knowing me it will probably be a Leica something. Which of these emulsions would you choose for sunny day fall foliage and why? Go!
