The Number of SIMPLEX PROJECTORS Installed In The GODFREY BUILDING Is More Than One-Third of The TOTAL NUMBER OF MACHINES USED BY LABORATORIES & STUDIOS IN AN AROUND LOS ANGELES DEAD MEN TELL NO TALES (Continued from page 3980) Such a luminous surface might be considered an ideal diffused light source. At a given distance, this diffused light source, as compared with the concentrated light source, would evenly illuminate a greater area at a proportionately lesser intensity. In the language of the studio, the light from the luminous surface would not carry so far as the concentrated light, but would be more scattered or diffused, producing an effect often very much desired in photography. If the light from a concentrated light source, such as a flame arc, for example, is passed through a piece of roughed glass or similar medium, a diffusing or scattering effect may be obtained, involving, of course, a loss proportionate to the absorption of the medium. Thus it is practicable to obtain almost any degree of diffusion from a concentrated light source; but the scattered light from a luminous surface cannot be concentrated. Another form of concentrated light, now extensively used as an auxiliary, is the projected beam or spot light. This is usually in the form of a high-powered hand-feed arc (70 to 100 amp. and often more), with a single plano-convex condenser. The principal fault with this form of unit is its low efficiency, probably mostly due to the filtering effect of the thick condenser glass. However, the striking effects obtained by this means will easily offset this inefficiency. It might be interesting and instructive to note the effect obtainable through a condenser lens of quartz as compared with the ordinary glass condenser. REFLECTORS AND REFLECTING SURFACES The uses of reflectors on various types of lamps are to re-direct the rays (which would otherwise go in useless directions) toward the object to be illuminated, and further to obtain by their use various degrees of concentration, according to the shape of the reflectors. While surface mirrors would probably represent the ideal reflecting surface, their use would hardly be practicable owing to the difficulty of keeping large numbers of them clean under the studio conditions.
