Mounting Bromide Enlargements

The first requisite for this is a water-tight tray, large enough to
hold the enlargements. A hard rubber tray can be purchased, or a wooden
one that will answer the purpose may be made. I use one of my own
construction that is cheap and serviceable. It is simply a wooden box,
27x32 inches and 4 inches deep, made of 1/2 inch grooved material and
lined with black oil cloth, not cut at the corners, but folded in. In
this, when about half full of water, lay the enlargement face up, and
let it remain in the water fifteen minutes. It should then be laid face
down on the wet cloth (which should be all ready) as described in the
preceding chapter, for mounting crayon paper. Care must be exercised to
have the cloth wet all over, for if there should be any dry spots in it
they would ruin the gelatin surface. With a cloth or squeegee remove
the water from the back of the enlargement and also from the cloth
around its edges, for if there is too much water on the edge of the
cloth it will work up into the paste and prevent it from sticking when
mounted. Now paste the enlargement and strainer according to the
directions given for mounting crayon paper, place the enlargement on
the strainer and rub it down by using the fingers wet in a little
water, or the squeegee can be used; and then trim off even with the
outside of the strainer. Avoid rubbing too hard along the edges, as by
so doing you will press out all the paste and it will not stick.

You can remount a bromide enlargement as often as necessary in case it
does not come out perfect, only bear in mind that you must not allow
anything dry to touch the surface when wet. But I should not advise you
to try more than three times directly on the strainer. It would be
better to mount a piece of crayon paper on a new strainer, and after it
is dry to remount the bromide enlargement on that.


After the crayon paper has been mounted on the strainer and dried, the
next step is to obtain the outline. I will first treat of free-hand
crayons, taking it for granted that the reader is not able to produce
crayons from life, but works from a photograph. There are five
different methods of making an outline, from which the reader can make
his own selection.

Make a negative from the photograph that is to be enlarged, and
construct for a room that is entirely dark, with the exception of one
window, a dark inside shutter, with an opening in it the size of the
negative you intend to use. Place a cleat on each side and at the
bottom of this opening, so that the negative may be made to slide in
front of it. Having removed the ground glass from your camera box,
fasten the latter against the shutter so that the opening comes in the
centre of the box. You can fasten it with four hooks and eyes, or
arrange cleats on the shutter and pieces on the box, so that it will
slide into place. Be sure and have the box come tight against the
shutter so that the light will be entirely excluded. Place the negative
over the small opening in the shutter and adjust the camera box; then
stand the easel with the crayon strainer on it at the proper distance
to give the required size of the enlargement and focus the image sharp
on the crayon paper. The strainer must stand at the same angle as the
shutter; that is, if the shutter is perpendicular then the strainer
must stand perpendicular also. Then go over the outline and shadow
lines with the charcoal, after which open the shutter and examine the
outline and see if it is right. As you are working in the dark you are
apt to overlook some lines. If you have done so you can close the
shutter again and make them. If it proves to be all right go over it
with the crayon point No. 2.
