Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...a sharp focus of the original, use a sharply printed letter or figure, such as is produced by copper-plate printing upon white paper or bristol-board.

This must be fitted upon the front, or glass side, of the negative. The object of these two masks is to produce a "safe edge" to hold the carbon image to the metal of the watch-cap, or to the face of the dial, during development. A touch of paste at each corner of the masks will hold them in position. The negative is now placed at the jfcSn center of a clean 4 x S 8lass plate, and held in position by two strips of gummed paper at the top and bottom opposite corners. The plate is turned over, placed in a retouching desk, and stumped so as to form a vignette. This stumping is done by cutting half-way down a smaller circular or flat bristle brush, dipping it into moistened opaque, and pressing this end on to the glass, so as to form a rugged-edged oval, which will...show more
