OF A DOUBLE EXPOSURE.]
Amateurs often obtain unexpected results from carelessness in exposing
their plates. Some very amusing pictures can, however, be obtained by
making two different exposures on one plate. The subject should, of
course, be of a very different nature. Our illustrations, Figs. 102-3,
are examples. In making these it is necessary to give a very short
exposure in each case, about one-half the amount that would be
ordinarily required. The negative must be carefully developed, using
plenty of restrainer. Similar effects can, of course, be obtained by
printing from two different negatives, but the results are, as a rule,
inferior.
