During my next printing session I will use up the last of my 8x10 Supra Endura and make the change to Fuji Crystal Archive II. I am sure that I am not the first to make this transition. What have you found the difference in filter packs and exposure for these papers to be? I am presently using 90M, 120Y for my filter pack and exposing an 8x10 at f/16 for around 12 seconds. Should I expect to need more or less filtration and how much? Will I see my exposures increase or decrease and, again, by about how much. For example, and change of -20M, and -50Y would give me a starting point of 70M and 70Y. If the Fuji needs a half stop more exposure my starting times for the initial test prints would be around 17 seconds.
