On this subject, I have a book to recommend, if the historical processes [and how they work(ed)] interest you: "The Keepers of Light" (subtitle: A History & Working Guide to Early Photographic Processes) copyright 1979.
Wow, WHAT a book. It provides an interesting historical account, but beyond that it is also a completely practical "how-to" for those who want to try their hand at: • Salted Paper • Ambrotype • Platinum • Palladium • Kallitype • Carbon • Carbro • Three-Color Carbo • Gum Dichromate • Oil • Bromoil • Photogravure I was fortunate enough to snag a hardcover copy of this "out of print" book for 1/3 of the going price, but after seeing it I can say that it is definitely worth having if you are interested in learning about (or pursuing) any of these processes. 301 pages of content (before pages of footnotes). Paperback on Amazon: http://www.amazon.com/The-Keepers-Light-Photographic-Processes/dp/0871001586/ Hardcover on Amazon: http://www.amazon.com/The-Keepers-Light-Photographic-Processes/dp/0871001683/ Reader reviews of the book on Amazon: http://www.amazon.com/Keepers-Light-History-Photographic-Processes/product-reviews/0871001586/ Hope someone finds this helpful. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
