The Digital Printing Handbook by Tim Daly
by Barry Stoch
First published in 2002 the first few sections on hardware and software are a little long in the tooth. Those sections aren't why you would buy this book though.
There are the usual walk through of general info on printing that cover the subject well, without getting overwhelming the reader in the technical aspects.
Where it gets really interesting is the wealth of techniques to imitate old darkroom techniques like selective toning, duotone, split toning, lith printing, salt-print process. All interesting easy to follow techniques to add levels of creativity to your finished artworks.
It doesn't end there however, the section on unconventional media provides a whole new world of expressing your photography by printing on uncoated papers and artist papers. One of the only books that I have seen that delves into this area, providing solid info from which to experiment.
Highly recommended if you are interested in pushing your photography into new directions that are creative and expressive.
