Procédés pelliculaires et leurs applications aux impressions aux encres grasses : conférence du 3 avril 1892
A French lecture pamphlet by George Balagny, published in Paris in 1893, on film-based photomechanical processes and their use in greasy-ink printing. Its plates are photographs of a rocky grotto, a village lane with a church tower, bare oak trees at a crossroads, and a stage ballet, which a designer might take from as examples of early photographic reproduction with rich tonal range, strong contrast and grainy, dark-toned detail.
