New Epson Complete Guide to Digital Printing
Contrary to what most people might think, making fine art photography prints is very a difficult task. If you don’t know how to turn a photograph into an extraordinary fine art print, you can’t really call yourself a fine art photographer.
Yes, you can outsource the printing, but if you don’t know how to print yourself, why do you think you’d know how to judge the quality of a photographic lab print?
There is simply nothing more important for a fine art photographer than knowing how to make a fine art photography print. That skill alone is what differentiates amateurs from pros in this business.
This book is the most complete guide on fine art printing to date, definitely a must read. Here is the book description from Amazon.com.
