582. Note

Note. When mixing the crayon and pumice, mix them in an ordinary dry-plate box, and only a little at a time. Spread the crayon and pumice well over the bottom of the box, so as to enable you to charge the stump lightly or heavily. When using the stump, before applying to the ground-glass first draw it over a piece of strawboard, practically removing all visible crayon, and then apply to the ground-glass.

583. Caution

Caution. Never apply heavily, even if you require a strong high-light, for if applied too heavily it is difficult to remove, and if the application is not heavy enough, it is a simple matter to go over the surface, or at least those portions that need strengthening, a second time, and touch them up a little. Just remember that the faintest amount of color will show; so be guided accordingly and you will, after a few experiments, be able to produce very pleasing effects.

584. In Illustration No. 44 is presented an enlarged negative with a worked-in background. The original exposure was made on a 5 x 7 plate, a transparency made by contact, and an enlarged negative made from the transparency. After developing the enlarged negative the background was locally reduced to very nearly clear glass. The glass side of the negative was flowed with ground-glass substitute, the design was faintly sketched on the ground-glass and then worked in with crayon, and the shadows were emphasized by etching on the film side of the negative.
