Re: pyro and cyano
<<<<<<<<<<Everything else (well, most...) looks like piece of
cake after being able to achieve consistent success with cyanotype. I was
shocked to find out how pt/pd is so much easier compared to cyanotype, for
I found the same when I started with argyrotype, which I consider the most ridiculously fickle process. I have few very good argys to show for months of exclusive dedication to it...but I will admit that I didn't buy $18/sheet paper to print on ;-)
Pt/pd has been a breeze comparatively...

Hi Christina, 10 Nisan 2009, Cuma, 6:45 pm tarihinde, Christina Z. Anderson yazmış:Bob, I quit using the hydrogen peroxide because it was questioned to perhaps compromise the archivalness of the paper and it was unnecessary because the print would eventually get to that dark blue anyway, PLUS it seemed to bleach the print a bit, though this latter is only subjective to me and another person or so.I don't think it will hurt the archival qualities of the paper if you use very little like a cap (5-10ml) into 1000-2000ml water, keep the bath sort (30-60 seconds is more than enough) and rinse well afterwards. That's what I do; I experience no bleaching at that concentration and timing...BUT this is my question--does the hydrogen peroxided print actually get darker blue than one that oxidizes over several days? So if it gets darker, there would be a benefit to it. I have not tested this.No it doesn't get darker. You just get the final result (w/o waiting a couple of days) as soon as the print is completely dry....
