The first edition of this book concentrated on the processing and printing techniques necessary to produce work of the highest quality. It outlined the structure and characteristics of monochrome materials and the principles of processing them. It described in detail modern darkroom equipment and procedures, both small-scale and large-scale, from negative processing and after-treatment to print exposure, development and finishing. Two important trends that were noted and discussed in the first edition have continued with increasing pace during the intervening six years. Today, more Multigrade paper is used than graded paper in most European countries and in the US, while the properties of XP1 400 film are now understood and appreciated by a growing number of professional and amateur photographers. This second edition has been revised and updated, dealing more extensively with the different types of Multigrade paper that are now available and with the latest systems of exposing them.
