of the enlarger and the density of the diffusing material.
Diffusing tends to lower image contrast; therefore, you
may need to use a higher contrast printing filter than
normally required for a given negative. The exposure
through the diffusing material should be about one third
of the total required exposure time.

with your test strips. Study this print and determine the
location(s) you are going to dodge, burn in, and so forth.
The application of these techniques may appear
time-consuming, but you will make professional-
quality prints that are rich in detail and mood.
silver. Because of this silver grain structure, enlarge-
ments, especially large ones, may appear "grainy." The
graininess of a print is a direct result of the graininess of
the negative and the degree of enlargement. The
graininess of a print, however, may be modified to a
limited extent during the printing stage by the following
smooth, glossy paper.
Crumpled cellophane, fine mesh screen, or a piece of
nylon stocking can be used as a diffuser.

movements that allow the film to be parallel, or nearly
so, with the subject, in spite of the viewpoint;

tilted by blocking it up on one end. A small
diaphragm opening (high f/stop) must be used to
increase the depth of focus to include both the part
of the easel nearest the lens and the part of the easel
farthest from the lens. Within the limits of what you
can keep in focus, you can correct some or all of
the distortion. With some enlargers, you can tilt the
negative carrier by propping up one side with one
or more coins.
