MONTHLY CHAT WHY NOT TRY BOOTH SHOWMANSHIP The low dollar volume at the boxoffice in movie theatres all around the country is the prime worry of the film industr) . The exhibitor says "give 'em a big picture and the public will bin tickets." And that checks out when the movie attraction catches the fancy of the mass public in this country and abroad, for the "big picture" grosses more millions today than ever in the "past. But the men with investments in theatre properties might well ask themselves "what are we doing about the situation of complete dependence on the people who make films?" IP would like to suggest that the theatre owner would give a try at Booth Showmanship. Since its pretty plain that there are millions of people who attend the movies infrequent!) (for instance when the "big picture" comes along) and certainl) not for the reason that they don't have the admission price — according to Washington the income is at an all-time high. Booth Showmanship is a good presentation of all pictures the theatre presents to the patrons. A picture that is bright from margin to margin of the bigger screens.

Mam a theatre has too large screens for the light source being used. This stems from the neglect when the theatre put in a large screen without stepping up the light source. There are cases when screen area was more than doubled using existing lamps. Naturally, the screen illumination was reduced radically, the projectionists, the patrons of the house, noted the dimness when they saw a black and white film especialh. when the low-key and night scenes, with color film dim at the margins. The equipment dealer is the best source for the theatre owner to get good advice to upgrading, at minimum cost, his booth equipment. According to informed equipment men. more than M'' of the arc lamps in theatres in this country are more than 20 years old. And the projector manufacturers say the same thing holds for projectors. During the last decade a lot of improvements in techniques have gone into the motion picture, particularly by the equipment manufacturers and the film makers. For all of the know-how of the production men, with their costly pictures, not every film attraction turns (Please turn to page 18) International Projectionist August, 7963
