Saturday I went to see a documentary about Andres Serrano at the Montreal festival of film about art, and they followed him during a photo shoot for the Comdie Franaise. This was a great insight into an artist's way of working, and if you paid close enough attention, you could figure out his entire toolchain, which is very simple, but very well used. Serrano was shooting 6x7 Provia 100 and having it printed as giant C-prints, face-mounted. I assume there was a digital intermediate, given that RA-4 is a negative process. His usual printing habits were instead Ilfochrome prints from slides. So my technical question is: Why would you print from slides onto digital RA-4 instead of Ilfochrome, digital or not? I'm sure you can cut costs significantly, but is that the only reason? Wouldn't negative film be a better match for a digital C-print? In the analog world, people print slide on Ilfochrome, and negs on RA-4, unless they are really good at doing internegatives/positives, but does the digital intermediate changes the rule of the game? Oh, and before you ask: No, they did not go into any details in the movie to explain the rationale!
