I recently tried (on accident) Fuji Velvia 100F. First off, wipe the word "Velvia" from your mind. It's NOT Velvia. I have no idea why Fuji calls it that. To me, Velvia was, and will always be Velvia 50, that oversaturated marvel that would not die. The saturation in Velvia 100F is subdued, pleasant, and very Astia-like. Provia to me is much more saturated.
