LAMPLIGHT EFFECTS Lamplight scenes which do not include figures present no difficulty, providing a suffi ciently long exposure can be given. Out-of-door lamplight effects are described under the heading " Night Photography." Indoor lamplight effects, with figures, may be obtained by concealing a piece of magnesium wire in the lamp, which is preferably provided with a globe or shade, or by having the magnesium in such a position as to give the effect of the light coming from the lamp, as described in the article, " Candle-light Effects." Daylight can also be used, and the following is H. Essenhigh Corke's method. An imitation or dummy lamp is used. First, a real lamp, alight, is photographed and the image enlarged to the same size as the lamp. The enlarge ment is mounted on cardboard, which is then cut to the outline and a strut placed at the back. The dummy lamp can be placed any where in the scene, and in the finished photo graph cannot be told from a genuine lamp. The
lamp and sitter are arranged near a window, of which all except a small space is blocked up in such a way that a strong light appears to come from the lamp and fall upon the sitter, the light tones graduating into darker ones on parts of the drapery and surroundings. The "lamp," being of thin cardboard, does not throw a perceptible shadow ; but a certain amount of light must fall upon its face, in order that the details may be shown. It may be necessary to use reflectors, as in ordinary portraiture. For lamplight effects it is more natural to retain almost all the shadow de tail, and not, as in firelight effects, regard only the high lights and half-tones. Exposure will vary, and must be a matter for experiment. The prints should be stained with an orange-coloured dye, such as eosine and methyl-orange aniline colours, or carbon prints on a suitably coloured support may be made.
