Bromide Crayons





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 surface of

the paper, there cannot be as much crayon put on the bromide

enlargement as on the other kinds of paper, and that, therefore, it

cannot be strengthened to the same degree in the shadows without

spoiling the nice transparent effect that a bromide should have there,

it follows that the best bromide crayons are those on which the least

crayon is used to produce the desired effect. The bromide paper, on

account of the gelatin surface, will not take the crayon from the stump

as readily as the other kinds of paper; but after the surface has been

treated with the pumice stone this objection is removed, and the paper

can be worked on with the stump readily. I can say from my own

experience, that for producing a crayon over a photographic enlargement

with the stipple effect, it has no equal in the beauty of finish and

rapidity of execution.



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.
