Earl, nice print, and nice photo! You got a great tonal range. I did my first cyanotypes with Mike Ware's process, and it was from using his process that I taught myself to acidify the first bath in the developing. I've never acidified my paper, but it's something I should look at after looking at your results. My top two papers for cyanotype are Twinrocker and Stonehenge. Stonehenge is inexpensive, and works well, but man, that Twinrocker hot press is pretty phenomenal. I just bought some 22 x 30 for some upcoming prints.
Funny thing though is I decided to try out the old process. I wasn't dissatisfied with the new process, but just thought I'd try it out, and I like it a lot, and I like the color of blue I get with it. It just works with my style of printing. I'm sure I'll continue doing both, but I can't really argue with the results I'm getting with the old process, especially with an acidified first developing bath.
I agree with you mostly with regards to toning. The staining of the paper is annoying. I found that I have less with using tannin, and I've made a few prints that I really like with it. My best efforts have been with a split-tone or duotone effect. But, the reason I do the process is for the blue.
My main limitation currently is lack of a UV light source besides the sun, but I'm working on that, and I'm almost done with my UV LED light version 2. Something about being married and having things to do seems to slow me down in my process. That and brewing beer seems to take a lot of my time... I've also not felt the creative urge a lot lately. I hope that's not a sign of change in me as I age, but just a passing phase.
Thanks for posting the document. I hadn't seen that before, and I'm looking forward to reading it. Mike Ware certainly has provide a great resource for the world, that's for sure!
