Catalogue of apparatus and materials required in the practice of photography, including both plate and paper processes : manufactured and sold by George Knight and Sons, philosophical instruments makers, &c., Foster Lane, Cheapside, London : illustrated with woodcuts
A trade catalogue issued in 1851 in London by George Knight and Sons, philosophical instrument makers of Foster Lane, Cheapside, listing apparatus and materials for early plate and paper photography for working photographers and amateurs. The pictures are small black-and-white woodcut engravings of cameras, dark boxes, stands and clamps, drawn in plain outline with hatched shading, showing how each piece is built and fitted so a designer can borrow its utilitarian, mechanical look.
