How to “Work Up” a Negative

See [Along the Canal]

“Along the Canal” was taken about mid-day in July in bright sunlight, Graflex 4×5, Cooke lens working at one-twentieth of a second, F 11, on Seed 26x plate, Pyro (Kodak powders) developer. In working up, first make Solio print and enlarge by photographing up to 6×8. On this negative sky and some trees were painted out, using glass side to work on. From this negative print was made on American platinum paper, first the foreground, then the sky printed from negative which will suit subject. Retouching can be done on this print with carbon pencil. You then have a print which can be enlarged to any size, using Smith lens. This print is on Spanish hand-made paper, hand-coated with platinum.
