1228 HANDBOOK OF PROJECTION FOR fundamental requirements of the modern theatre projection room, because, while it is a first report and neither perfect nor complete, still it is the best thing now available on the subject. The formulas used therein were worked out by that brilliant motion picture projectionist, Chauncey Green of Minneapolis, Minnesota. This report has been considered and has been adopted by that body of conscientious, capable engineers. It will be, in due time, added to, but as it now stands it offers suggestions which have been approved and formulas which the architect may use and which will be for him a guard against error in the matters covered. The architect may disregard these laws and suggestions, true; but if he does, then the quality of reproduction, either optical or acoustical or both, must and will inevitably be injured and lowered. A REPORT OF THE PROJECTION COMMITTEE OF THE SOCIETY OF MOTION PICTURE ENGINEERS F. H. Richardson, Chairman. Arthur H. Gray. Lester B. Isaac. Chauncey L. Greene. J. H. Kurlander. Herbert Griffin. Harry Rubin. Mark S. Swaab. TO THE SOCIETY AT THE SPRING CONVENTION MAY, 1929
