Chemistry for Photographers by Allen R. Greenleaf.

 Amphoto, 1941. Fine hardcover with dust jacket. Summary:

Published in 1941 by the American Photographic Publishing Company, Chemistry for Photographers by Allen R. Greenleaf is a classic technical manual designed to demystify the chemical principles underlying traditional darkroom practices. Written for both advanced amateurs and working professionals, the book bridges basic chemical theory with practical photographic application.

The text systematically covers the fundamental chemical reactions involved in light sensitivity and film processing. Key topics include the composition of light-sensitive silver halide emulsions, the behavior of reducing agents in fine-grain developers, stop baths, fixation (hypo), bleaching, and post-processing techniques such as intensification and toning. Greenleaf provides chemical formulas, reaction explanations, and practical advice on solution preparation to help photographers achieve optimal control over image contrast, grain structure, and archival permanence.
