Step by step instruction guide on one of the most artistic of photographic processes, gum dichromate printing. Particular emphasis is placed on the production of full color photographs. Written by Luis Nadeau who, at the time this book was written (1987) owned and operated the only Fresson lab outside of France and was the first to commercially produce permanent tricolor carbon prints.
Luis Nadeau , Canadian author , is considered the reference for all Alternative Printing Processes . This used to mean Alternative to Silver Based printing , but nowadays it means alternative to Digital Printing .
In essence Alternative Printing processes , among which Carbon Based Processes is the most "Expressive" are considered to be "Fine Art Processes" since they all require extensive personal involvement , from capturing an image in film , specifically tailored to the Gum Dichromate Carbon process , then "Hand Making" your Pigmented Dichromate Sensitized paper , followed by printing it using the sun as a source of Ultra Violet light .
There are many books on this subject but they all have Nadeau as a reference of authority.
