The modern practice of retouching negatives, as practiced by French, German, English & American experts
A photographic trade manual on retouching negatives, written by Paul Piquepe and published in New York in 1889 by the Scovill & Adams Company for working photographers and retouchers. Its pictures are plain black-and-white engravings of equipment: a hinged retouching desk with a tilting glass top and a hand magnifier with a wooden handle, both drawn with crisp hatching and clear outlines that suggest simple, legible diagrams for studio furniture or tool icons.
