from the light entering through the open doors should he taken.
Exhibitors who pay perhaps hundreds of dollars a week for film service, and who fail to give proper attention to such details as these are doing a very foolish thing. Most emphatically a screen which is struck by any light other than the picture light itself does not give the best possible result.
Awnings on the outside of the window will serve very well, especially if made of dark cloth, and will not interfere with ventilation.
Small town theatres which have windows opening directly outdoors may exclude the light effectualy by means of double, dark colored window shades, the edges of which run in grooves not less than one inch deep. These grooves may easily be built by a carpenter, and the plan will be found quite effectual. One shade will do, but two are better, since the single shade is likely to develop pin holes which will admit light.
Standing beside the screen, looking toward the auditorium, there should be no unshaded light source visible to the eye at any point. If there is, then the light from that source is reaching the screen and injuring the result.
Indirect lighting is a most excellent form of auditorium illumination, provided it be properly installed, but this is by no means always done, the most common fault being the installation of fixtures too close to the screen end of the auditorium.
Reasonably dark colored, non-reflective wall decorations are a great aid in eliminating stray light ; also they are very restful to the eye, though by this we do not mean to infer that the decorations of a theatre should be sufficiently dark colored to be gloomy.
DISTRIBUTION OF REFLECTED LIGHT.— One fundamental requirement of a screen surface is that it as nearly as possible reflect light equally to all seating space in the auditorium, so that the picture appear as brilliantly lighted to those patrons seated at a heavy ?ngle to the screen, or to those seated in the balcony, as it does to those seated in the center of the orchestra floor. If the screen exhibits a certain degree of brilliancy to those seated in the center of orchestra floor, and a lesser degree as one moves around to one side of the house, it is said to have "fadeaway," and just in proportion as the screen develops this characteristic it is a
