[Halftone plates in Half-tone on the American basis]

Cronenberg, Wilhelm. Half-tone on the American basis · 1896

"12 Half-tone plates from photographs and art. Excellent description with very clear explanation of the formation of the dot on the negative and the importance of the shape of the stop and its distance. Plates made by students at the Practical Institute for Photography and Mechanical Reproduction, Schloss Grönenbach, Bavarian-Algan...This book was one of the first to explain the half-tone method to beginning process workers so that they might grasp the methodology and theory."--Hanson Collection catalog, p. 125
