When I. exhibit my best prints to an appreciative audience, I feel akin to the Wizard of Oz. Dorothy and her companions were supposed to see only that majestic head with the spouting flames and smoke and to ignore the little man behind the curtain pulling the levers. If I am successful as a printmaker, my viewers look at my work with joy at its beauty. They don't note the tricks, manipulations, and outright visual deceptions that go into making a print that inspires awe.

7 I've been doing serious photography for 37 of my 51 years. By the time I'd taught myself how to make dye transfer prints from my color negatives, back in 1975, I thought I. was a pretty hot printer. Now I know I wasn't half as good as I thought. Twenty years hence, I'll look back and again be embarrassed by how much I thought I knew. Fine printmaking is an everlasting learning experience for all of us. When I began my life in the darkroom, prints were still universally made on fiber- based paper, C-22 processing was standard for color negatives, E-3 was still common for some transparency films, and Cibachrome (now Ilfochrome) had yet to take its place in the darkroom community. Many materials available to the typical darkroom worker have improved immensely. We have also seen changes for the worse.

8 Dye transfer printing was killed by Kodak in 1993. Although a few other printers and I still make these finest of prints, our supplies are limited and our prospects for ever getting more are uncertain. Although materials have changed over the years, I've found the principles of fine printing haven't. Master printmaking is a discipline requiring both talent and knowledge and no small amount of legerdemain. The discipline doesn't come from the specific printing materials one uses or whether one prints black and white (B&W) or color or even whether one works in the darkroom or at a computer. The methods of fine printmaking are rooted in our own perceptions, the ways the human vision system sees the world, the ways that photographic materials see it differently, and immutable laws of optics and nature.

9 This book is not a primer on photographic printing. I'm not going to tell you how to develop a roll of film or process a print, and I assume you have a working knowledge of photography. Its purpose is to teach photographers the refinements of photographic xi printmaking, to take them from making those merely competent prints to making excellent ones. This book brings together disparate fields of knowledge, distilled from my three decades of learning and experience in color and B&W photographic printing. In learning about both a human's and a film's perception of the world, you'll pick up some informational tidbits about color theory, the nature of the human visual system, information and measurement theory, neurophysiology, and other arcane topics. Still, most of this book is about tools, techniques, and darkroom procedures; I intend this to be a practical book, not one of difficult-to-apply theory.

10 Even novice printers can learn from this book. Some of what I say is pretty fundamental, but it is information most photographers don't know and won't find in the average photography book. I intend this book to be useful to anyone making color or B&W prints, including people working with a computer instead of an enlarger. One can't entirely fix an ineptly photographed image on a computer any more than one can fix it in the darkroom. If one doesn't understand the principles of good printmaking or have a real understanding of what the viewers truly see when they look at a print, one is no more likely to produce a truly fine print with the aid of a computer than with an enlarger. The tools change, but the principles don't. Results speak for themselves. You can see several dozen of my finest photographs on your computer.
