I run a small print shop in South Pasadena and thought I'd put together a couple shelves of books on technical topics in photography (not only large format) for the community here. Wanted to see if the forum had any suggestions for books they've found especially useful over the years. Would appreciate an emphasis on books that aren't particularly expensive since I'd prefer to be able to loan them out on the honor system. Thanks for your feedback.
