Necessary Background Information Certain background information is necessary in order to make the best use of the pinhole aperture. For instance, it is possible that the screen surface in use will tint the light reflected from it in such a manner as to make the picture appear to be on the yellow side of white. If this is the case, it may be found advantageous to set the lamps just a shade on the blue side of white. It is also frequently found that the auditorium incident lighting may add extraneous color to the screen, and this may make the best white light setting of the lamp appear to be less desirable than some other color of light. Good practice will suggest the replacement of screen surfaces which do not respond properly to good illumination of normal color, and whatever the projectionist can do to keep auditorium light from the screen will be a step in the direction of better projection. But there is no gainsaying the fact that the pinhole aperture is an invaluable aid to consistently good screen light. For accurate and daily adjustment of the lamp, it stands without a competitor in the areas of simplicity, accuracy, and economy. Q; When is a mistake a blunder?
