The dictionary of photography for the amateur and professional photographer
A photography dictionary compiled by E. J. Wall and Thomas Bolas, published in London by Hazell, Watson & Viney in 1897 for amateur and professional photographers. Its pictures are plain black-and-white line diagrams of lenses and light rays, with ray paths drawn as straight lines from object points through lens elements to focal points, useful for designers wanting clean technical schematics of optics.
