I've only tried processing reversals once, and that was 10 years ago. I'd like to try it again. I have a test roll of velvia 50 and provia 100 ready. can anyone give me the development times for the two emulsions.
IIRC, the Kodak E-6 kit I've got in my darkroom specifies a "6-7 minutes" time for the first developer. I've seen claims by some that Fuji slide films work better at longer first developer times than Kodak slide films require, so I've been using 7 minutes for my Velvia, with good results.
