A mid-nineteenth-century English photography manual, edited by Charles Heisch from Gustave Le Gray's French treatise, published in London in 1852 for amateur and professional photographers working with waxed paper, albumen and collodion. Its pictures are plain line diagrams of stereoscope apparatus, camera mechanisms and a sloped copying board, drawn with hatching and lettered parts, useful to a designer wanting clear technical schematic linework.
