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.
