Any of the methods employed for making a bromide enlargement may also be used for making an enlarged negative, that is, by replacing the small negative by a positive transparency and enlarging this on to an ordinary dry plate. For cheapness, and with some subjects, bromide paper may be used for such transparent-v, developing rather dense with a strong but well-restrained developer, and, when dry, waxing the print and heating over a lamp. The best kind of transparency to use is one by the carbon process, as these are most free from grain and give the best gradation. As the emulsion used on dry plates is considerably quicker than that used for bromide paper, and is consequently more liable to fog, it is advisable to use an enlarging camera where the plate is enclosed in a slide. Enlargements are best made by daylight, otherwise there is a tendency to hardness.
