Double Exposures
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.
