Part 3 — Distance Marker for Printing Photographs

A convenient homemade printing device, or distance marker, for printing photographs by artificial light consists of a smooth board on which twelve 1-in. marks are drawn, as shown. A wall-base electric socket is attached on the first line and the others are numbered up to 12. A trial test of a negative marks the distance and time of exposure which should be recorded on the negative. Such a device makes uniform prints possible and provides a means of recording time on negative-storage envelopes.—Contributed by Harold Davis, Altoona, Pa.

The Same Distance with the Same Exposure will Always Produce Uniform Prints
