I want to explore a number of different Victorian printing processes over the next few years, with an eye toward platinum/palladium as my goal. Pt/Pd looks pretty expensive so I thought that other methods, such as salt and Van Dyke printing would be good practise in learning how to coat paper, etc. My question is, would the contrast range of the negatives be the same for these different processes? I have an interesting book on printing (Secrets of Salts) but none of how to process negatives for these types of prints. Any suggestions as to a good starter book? I will shooting 5x7 and 8x10.
