Crayon portraiture; complete instructions for making crayon portraits on crayon paper and on platinum, silver, and bromide enlargements, also directions for the use of transparent liquid water colors and for making French crystals
A technical manual by Jerome A. Barhydt, published in New York by Baker & Taylor in 1892, teaching commercial photographers and portrait finishers to work up crayon portraits over platinum, silver, and bromide enlargements. Plates pair crosshatched studies of facial features with line engravings of studio apparatus, giving designers dense stipple and hatching textures plus a magic-lantern projection setup in raking light.
