    OK, I've tried, I've really tried, but I just can't seem to get EVEN toning with this process. It makes no difference if I smile or frown, chant or hum or work before or after midnight. I'm using Centennial POP and the B&S Gold Toner. Whether I agitate like a madman or whether I just let the print sit in the toner, I cannot get a nice uniform toning effect. The edges go gray or less brown (depending on how long in the toner) compared to the print center. This evens out a bit in the fixer step but not enough to not ruin the prints which are a beautiful tone in the center but gray at the edges. What am I missing here? This is a beautiful process, using my pyro negs that work well for Pt/Pd, but I just can't seem to get past this step. The only thing I've thought of trying is to use 16x20 paper instead of the 11x14 paper that I am using for my 11x14 negs hoping that the uneveness will stop before reaching the image area, but this may be a vain and expensive hope. Is there a technique that will bless me with even toning??? Any insights appreciated!

    Richard, check with B & S, they might have some info that would help. I know a couple of locals who use pop, I will ask them if they have had similar problems.

    Hi, have asked around, and the answer is no, they havent.

    What size tray are you using? Are you getting enough aggitation at the edges?

    Use a larger tray (16x20 for 11x14 prints).
    Use at least 2 liters of toner in a big tray.
    Use a more dilute solution, and tone longer.
    Use gold borax.

    You know, if the edges of the paper are curling (and I know from experience they do), that could account for your uneven toning. If your solution is strong, it'll only take a few seconds to cause a noticeable difference.
