I realize this is a mind-numbingly stupid question, but what the hell. I bought a lot of VERY expired EIR that has shifted very cyan. Is there any way to filter it to try and get it back to "normal?" I'm already planning on rating it at 100 and pulling 1 stop in processing to try to regain a bit of dmax, but it still is pretty far gone (no real surprise there, but hey...it was CHEAP!) Anyway, any thoughts out there?
