I picked up some Crystal Archive and found as Ed did that it doesn't have any documentation. It is also missing basic filtration settings on the box. The Kodak Endura paper has filtration and on the one and only box of it I have tried the filtration was essentially right on for Kodak films. Do you know if CA has a standard starting filtration pack, or do we need to do this with trial and error? Maybe it's so consistant they don't print it?
