A complete treatise on the art of retouching photographic negatives : and clear directions how to finish & colour photographs
A photography manual published in London by Marion in 1898, written by Robert Johnson as a practical treatise on retouching negatives and finishing and colouring prints for photographers. Its pictures are engraved trade illustrations of cameras, a magic-lantern style projection apparatus, and photograph albums with mounted portraits and views, showing late nineteenth-century studio equipment in clear hatched line work that a designer could use for period technical diagrams and vintage catalogue layouts.
