It's been several years since I've done any serious darkroom work and I was never particularly masterful. I am coming out of hiatus now and would like to print on some special stuff I've had locked away. In particular, I'm hoping to make use of my large stash of Ektalure G, I'd like to try Ansco 130, and I'd like to get more into toning. I have some weak spots in my technique and I'm unsure how much practice, and how to practice, before I break into the stash. The paper is graded, so split-grade printing is a non-issue. I have basically anything I could possibly want available to me where I'll be printing. My aim is to make the best prints possible (I guess that goes without saying but sometimes we can afford to be a little sloppier than others) Here are my weak areas: I have little experience with toning. I'm particularly keen on doing more work with gold toner, though I suppose I should give Selenium a real go first. I've never printed larger than 11x14 and I am terrified of printing on my 16x20 Ektalure. Can anyone give some advice or recommend some resources (books or other) with sophisticated discussions of toning? I'm aiming for precision since the paper is irreplaceable. I tend to be a little too judicious with my test strips. Also, any resources or words of advice on printing large? Also, I am facing the option of Diffusion or Condenser and have not used a diffusion head before.
