Evening work for amateur photographers
A late nineteenth-century London manual by Thomas Cradock Hepworth, published in 1890, teaching amateur photographers how to make their own equipment and slides for evening work. The pictures are plain line drawings of workshop apparatus: a lantern-style printing frame with a central screw and side guides, a flat printing frame with corner clamps, a wooden stepped slide-holder rack, and a hinged wedge-shaped plate jig; a designer could borrow their clean technical diagram style and labelled plan views.
