ense sky, first make a test-strip or two, noting how long
the shading is carried on and how long the light is allowed to act on the
whole. If the sky is then over- or under-printed we can modify it in the
enlargement proper.

The best arrangement for vignetting in enlarging is a piece of cardboard
the size of the negative, with an opening cut out at the proper place and
about the size of the portion of the negative to be vignetted. This is
held near the lens and moved backward and forward between the latter and
the screen, the opening showing larger as we near the lens and smaller as
we recede from it. Very tasteful vignettes can be made in this way. A
favorite method of the writer's is to use a sheet of bromide paper,
preferably that with rough surface, and print on it a small vignette of a
portion of a negative. These sheets being of a uniform size are then bound
in book form, and make very attractive souvenirs. Variety can be added to
the collection by printing some of the pictures through a mat fastened on
the screen over the paper, when, of course, they are bounded by straight,
sharp lines.

Double printing in enlarging is not at all difficult. Assuming that
test-strips have been made determining the proper exposure for each
negative, I will briefly outline the process. Taking a landscape negative
with clear sky in which we wish to print clouds, we first tack on the
screen a sheet of paper the size of our bromide, and after properly
adjusting and focusing it, trace with a pencil the outline of the skyline.
We then remove the foreground negative and, after tracing, cut out a mask
conforming to the size and shape of the foreground, cutting away the sky.
We now put in the box the sky negative, and readjust our sheet of paper
until after proper focusing the desired portion of the sky occupies the
portion reserved for it, leaving the thumb-tacks as a guide when we put
our bromide on the screen. Now using the sheet of paper as a guide, place
on the edges of the bromide paper two little pencil marks to show how far
we shall shade the lower portion of the paper. Our mask being the size of
the foreground negative, it is now only necessary to hold it at the proper
distance from the lens to have its edge conform to the sky-line when
enlarged. But this would leave a sharp line if held exactly at that point,
so using the pencil marks on the margin as a guide, we slowly raise and
lower the mask very slightly and just sufficient
