How Much More Light for 3-D . . .Wide Screen?
When the screen found its voice more than a quarter century ago, the question, "How much will it cost?" was asked — if at all — from force of habit. Every showman knew he had to buy sound, just as he now sees the necessity for new equipment to handle the latest epochmaking projection techniques.
History Repeats
Exhibitors today are hurrying to exploit the terrific public interest in 3-D and wide screen showings— spending thousands and tens of thousands of dollars on new optics, screens, sound equipment . . . But what about screen lighting?
Light Losses Terrific
For 3-D and wide screen you need more light. Much more light. In almost every instance, regardless of theatre size or present equipment, you need ALL THE LIGHT YOU CAN POS
| SIBLY GET!
i
If that seems like a broad statement, just consider 3-D light losses, for example. Even with two projectors trained on the screen and
with screens of much higher reflectivity than before, you give your patrons only about half as bright a picture as you previously furnished with conventional films!
Wide screen — same story. In this new medium, projection light is distributed over 2Vi times the area of ordinary screens.
New Equipment the Answer
To repeat — you need all the light you can get. This means new equipment — equipment to operate the higher-capacity carbons at maximum currents.
Give your patrons — and these great new entertainment media — the light they need. Don't delay— call in your theatre equipment supplier for a complete diagnosis of your projection lighting needs.
