MONTHLY CHAT ITS technical excellence assured from the very start, Intertaional Projectionist, looks for new worlds to conquer. And finds them. The typographical beauty of our first issue, which induced so many fine comphments (for which we thank you one and all), has set eur contemporaries to hustling. One new cover has already appeared; and we hear rumblings of still another new cover, with an accompanying slight reduction in overall size. This last move is one near and dear to our own heart (don't mention it). This service by us in the cause of ART is performed with cheerful mien; but we can't withhold the observation that a mere new cover or a change in overall size will fail miserably in matching the high editorial standard we have set. GREAT chunks of publicity were spread over the landscape of this fair country by the recent demonstration of television at the Broadway Theatre in New York. Most of this pubhcity was along conventional lines: "television arrived" and all that sort of bunk. Nothing to worry about, gentlemen. Absolutely nothing. HARDLY a week passes now but what a new indication is had of the increasing interest of the industry as a whole in the quality of the image on the screen. Sound production and reproduction has had more than its share of attention, to the obvious neglect of picture projection. Who is there who will say that the picture in the average theatre today is anything but terrible? No one. Pictures that appear on theatre screens these days would have been laughed at in, say, 1925. Now, however, the "big boys" are waking up to the serious consequences of a poorly projected picture. Plans are afoot to improve the screen image. Who knows? the "big boys" might even buy a few dollars worth of equipment. Anyhow, they are once more aware of the existence of a projection room in the theatre. THE ever alert Academy of M.P. Arts & Sciences is sponsoring new aperture standards for cameras and projectors, complete details of which are printed in this issue. The proposed new projector aperture is .615 x .820, which size appears to us to be very close to the safety mark. Whatever standard is finally adopted, projection will benefit greatly, and Portland, Maine, and San Francisco will once more be in agreement as to picture size. Score another for the Academy.
