c. Or, as shown in Figure 210, a dodging device can be made by placing
an opaque, properly shaped piece of material on a wire handle. The shape of
the dodging tool should approximate the shape of the image area to be
lightened. It should also be slightly smaller than the area to be dodged.
This is necessary because as the tool is moved further away from the paper,
the area covered by its shadow increases. Although dodging is generally
necessary for only part of the exposure time, the device used must be moved
up and down slowly and constantly to blend the areas receiving various
exposures together, thus preventing a sharp line between the area dodged and
the other parts of the image.

d. Another form of print control, burningin, is used to make an area
darker. This is done by using a piece of cardboard or paper with a hole cut
in the center that is smaller, but approximately the same shape as the area
to be burned in. The device used for this procedure need not be complex.
Figure 211 shows a sample device in use. After the normal overall printing
exposure has been made, the burning in device is moved into position between
the lens and the easel. The card holds back all the light except the light
passing through the hole to the area that
