I just ran across a method for printing with pt, pd or pt/pd that sounded interesting and simple. I have been looking for a way to proof pt prints without the expense of using the pt/pd solutions, this is important when printing 12x20, so while looking at the alternativephotography site there is an article about satista prints. The process sounded simple and I had the chemicals, so I gave it a shot....amazing! the prints that came out have a great tonality and the process is so simple it is a wonder nobody has mentioned before. Those of you starting might give it a try, it is simple, far simpler than kallitypes or salt prints and it might represent some savings while you get the hang of it.
