Color. L.P. Clerc's Photography, Theory and Practice: Colour Processes.

Volume 6 in the series.  This volume by S. Welford.  AMPHOTO, 1971.  The U.S. edition prepared by Focal Press in the UK. Hardcover in gray cloth, like new with near fine protected dust jacket that is age-toned on the inside.  Originally published in one volume in 1926 by Louis Philippe Clerc as La Technique Photographique, it was first issued in an English edition in 1930 and reprinted several times. This thorough update and complete revision of his seminal work on photochemistry and related topics required multiple authors and volumes, of which this is the one on color photography, expanding on the basic principles provided in Volume 1, Fundamentals.  Here Welford provides details in chapters on chromogenic development, dye transfer processes, sensitometry, reversal transparencies with incorporated color couplers, color negative processes, color papers, printing color negatives, processing (including equipment), prints from transparencies, silver dye-bleach processes (like Cibachrome), Polacolor, image properties, perception and the reproduction of color, measurement of color, masking to improve the quality of reproduction, et al.  Illustrated with numerous diagrams, charts, etc. This book is quite uncommon in hardcover with dust jacket except for ex-library copies lacking the dust jacket.
