My Process PDF's
These are the handouts I used when I taught at the Minneapolis Photo Center, and later at my own studio. Feel free to download and use for your own purposes. Heads-up though - these are the write ups of the way I do my own work. I make no claims at being an expert, but my students got great results - and so do I... if I may say so myself.
Gum Bichromate - this is for the single negative way of printing. I do not cover paper prep, since that can be pretty personal. I mount mine to aluminum sheets with a dry mount press and a product called fusion 4000. I also just realized I have a typo! When I talk about mixing paint/gum/sensitizer I refer to it as - .1 gram gum, 1 ml gum, 1ml sensitizer. That first unit should be PAINT - .1 gram PAINT, 1ml gum, 1ml sensitizer. Keep an eye out for that, but it should be obvious. Sorry...
If you want to make 3 color prints, here is the way I make my negative sparations for it, then you will refer back to the first paper for the paint mixing technique.
Cyanotype- this process is pretty simple. I liked to show students exposure and evaluation, so I did not write it in the handout. It's hard to explain, really, but you want the edges that stick out beyond your negative to go a gun-metal grey color. You can use a split back frame to check the exposure, which for me almost goes reverse, but what I look for is just the lightest amount of yellow in your brightest highlights (when you're doing it for real that will make sense...) Process under slow running water until highlights clear to paper white, toss in a tray of water with a capful of Hydrogen peroxide (drug store stuff) for about 30 seconds to puch up your blue. Rinse again and hang to dry.
Salted Paper - this process I spent a lot of time working on. It is one of my favorites - after gum bichromate. There are some paper considerations to be taken when reading this handout, but I have had great results with Fabriano Artistico hot press paper.

Polymer photogravure - this process can be complicated, since it is as much printmaking as it is photography. I taught myself this process in an independent study in grad school. I got it to where I was getting the results I wanted. This is what I learned along the way. If anyone wants to give this one a shot, for this I'm on the fence about reccommending taking an actual workshop. It depends on your patience and ability to problem solve - and access to the necessaries.
Sorry they're not here yet, but eventually I will have up my curves folder for making the negatives. If you're dying for one write me and I'll get it to you. I got a new computer and that folder hasn't made the migration yet...
Best of luck! Remember, these are just my outlines on how I personally do things. Others will do things differently or hold different opinions. You can e-mail if you like, and I'll help as much as I can, but only so much can be conveyed online. If you want to meet up and go over stuff let me know, but yeah, I'll charge, but it'll be cheap...
