    Edwal Ultra Black Print Developer

    Any guidance on the 8x10 capacitiy of one litre of working solution with a 1:15 dilution?

    The Edwal information is vague at best (including the Customer Service department)

    Thanks in advance

    I use it one-shot, and it has never gone bad during a printing session. How's that for vague? If I had to guess, I'd say 30-50 prints over 3-4 hours.

    My results were different than arkoshkobash's - I found that after about 15 8X10 prints I started seeing a substantial drop in contrast. I can't remember what dilution I used though. And also two hours in the tray was about the limit before some sort of replenishing was needed. My results won't necessarily be yours, but this was my experience. I have since moved on to a different paper developer (BW-65 from Photographer's Formulary) and am quite a bit happier than I was with the Edwal.

    Ultra black is my favorite paper developer...I only use it as a one shot...I get pretty decent capacity. I've found the drop off to be pretty sudden rather than a slow degredation. I get a good 3-4 hours and 25+ prints pretty regularly. I also prefer the 1:9 dilution.
