Check in some used book stores or ebay (e.g. http://cgi.ebay.com/Time-Life-Photog...QQcmdZViewItem) ... Time/Life had a series of excellent books on photography (silver covers with black bindings about 11-1/2 square). The two books you want from the series are "The Print" and "The Negative". I've seen them many times when poking around book stores. The books are one of the best primers I've seen, and I taught this stuff for many years.
