Xow, the amount of spread-ing, and therefore the degree of softness,will depend upon the distance the vig-netter is from the negative, and the kindof illumination which the negative is toreceive. This is the point where themajority of inexperienced workers stumble,the vignetter being mistakenly fixed too. 245.—Pl.\te-box Vignetter. close to the negative. A moments con-sideration will show that the farther thevignetter is from the negative, the greaterthe spreading of the light, and that thefarther the light spreads the more deli-cately must it shade off from one tone toanother. Moreover, where the source oflight is small, such as that used whenprinting bromides, a sharper shadow willbe cast. Where the source of light is large, i PREPARING THE NEGATIVE FOR PRINTING. that is, where diffused light is used, suchas ordinary daylight, the vignette will bemore inclined to spread unequally. Itwill have been seen that the thinner thenegative the moi-e the light will stray;such portions require more shading—thatis to say, the vignette must come a littlecloser, and in extreme cases it is evennecessary to lay a little cotton wool overthe part. The cotton wool must have thesoftest possible edge, which may be ob-tained by pulling it ou
