I'm doing Brighton Beach Memoirs and want to do a pre-show wash creating a sepia type feel. Am I fooling myself that I can do with with just some amber gels and some soft focus breakup gobos? I also plan on using this to fade the focus on parts of the set when the focus should be directed elsewhere. I've read so of the negative aspects of attempting sepia onstage, but this is an application where I'm not trying to hold audience focus, in fact, just the opposite. I want it to be there, but more as a memory (photograph) while action plays on another part of the stage. Any one with ideas? This is being done with mostly source 4s and fresnels.
