✦ Synopsis

gm. For use, dilute with an equal volume of water. For some lines of work, especially photomicrography, the second development may be omitted. Given a good exposure and a good first development,the oxidizing agent is then applied until the silver deposit is completely removed. The plate is then washed and dried. The unchanged silver bromide will act as the opaque coating, upon which the correct color effect depends.

Striking effects can be obtained by the use of autochromes in photographing the colors produced by the transmiss'ion of polarized light through rock section.
