    Changing from Supra Endura to Crystal Archive II

    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.

    Very generally, I have found that exposure times are typically shorter than with Supra Endura, and the filter pack is generally lower as well. That doesn't mean that your results will be similar.

    Supra needed more red filtration as it aged. I aslo found less filtration and faster paper when I moved from Supra, some thing less that 60 in Y and M.

    I aim to adjust aperture to stay between 5 and 10 seconds. I understand that longer exposures can lead to reciprocity failure at different rates for differnet colors. I have not vigorously tested this, just stuck with guidelines in literature I read 20 or more years ago.
    my real name, imagine that.
