In the bromide enlargement, while the paper has to undergo all the different manipulations of development, fixing and washing, that the platinum and silver enlargements do, yet the gelatin is not removed, and, when dry, remains as a strong sizing to the surface of the paper—in fact, so strong, that in some of the different kinds of bromide paper the surface is very nearly as hard as glass, and, therefore, the crayon cannot be used upon it with good results until it has received a special treatment, as the crayon would only make a black scratchy mark. It has been said that the bromide paper and enlargement were entirely different from the platinum or silver enlargement and the crayon paper. While there is not as much difference between the bromide and other enlargements as there is between the former and the crayon paper, there should be this difference: the silver or platinum enlargement should only be printed strong enough to give the form and the larger details in the negative, while the bromide enlargement must be as nearly a perfect photograph as can be produced from the negative. From the fact that, on account of the difference in the The illustration facing this page was made from a crayon executed over a bromide enlargement from the original negative. Better results can always be reached in a bromide enlargement when it is thus made from the original negative. The student will notice in particular the stipple effect in the reproduction. |
