“One Moment Please”
A. G. TATUM, projectionist at the Ritz Theatre, in Ballinger, Texas, submits the following predicament for our dopey dare-devil and thereby wins a dollar. See what you can do.
That time OT Sam, engrossed in the art of sign writing, failed to thread up before changeover time and thereby caught plenty of abuse from the Boss, who had taken Sam's word that he could handle both jobs okay for an extra pitch in the pay-check.
Testing the Screen
A Timely Precaution
If your screen has been in use several months and you are not sure of its efficiency, there is probably no better way of testing it for brightness and light distribution than by actual comparison with new screen samples which are available through your dealer.
Three samples, representing the three
different types of screens diffusive, reflective and beaded — can be used at the same time by simply clipping them side by side onto the front of the old screen by means of paper clips. Then throw on the picture. A few minutes observation, from various angles and distances, will enable you not only to determine the comparative efficiency of the old screen but to see which of the three types is best suited for your house.
