Le développement en photographie : avec le procédé au gélatino-bromure d'argent
A French photography manual by Frédéric Dillaye, published in Paris by Librairie Illustrée, J. Tallandier in 1900, teaching gelatin silver bromide development to amateur and professional photographers. Its plates are halftone-style photographs printed on the page, rotated sideways in the scans, showing landscapes, a dark shoreline with a boat or quay, a cow or ox in a field, and a village street with figures and carts, each captioned as a phototype made with the process described. A designer might take from them the tonal range and soft grain of early gelatin silver prints, and the way plain documentary views sit within a text page.
