I'm being gifted with 20+ rolls of Velvia in 35mm. It's not my normal cup of tea, and I don't usually do E-6 (yet ANOTHER process to have to learn! I'm just warming up to C-41!). Anyone have any thoughts on IF Velvia cross-processes well, and if so, recommendations for how to do it (overexpose by how much, how to tweak the processing, if any, etc)?
