Nudes - Photogravures and Other Processes

20th century nude photogravures, heliogravures and other photo-mechanical processes. G. L. Arlaud, Andre de Dienes, Stanislaus Walery, Walter Bird, Paul Jsenfels, John Everard and many other photographers. WARNING: IF YOU ARE OFFENDED BY THE NUDE BODY DO NOT VIEW THIS AUCTION! These are not photographs, but either photogravures, or other types of photo-mechanical processes. Photogravure is an intaglio printmaking or photo-mechanical process whereby a copper plate is grained (adding a pattern to the plate) and then coated with a light-sensitive gelatin tissue which had been exposed to a film positive, and then etched, resulting in a high quality intaglio plate that can reproduce detailed continuous tones of a photograph. Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect. Offset lithography is a printing process that involves transferring an image to an intermediate surface before printing it onto the final sheet.
