We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

LIGHT CONDITIONS 115 4. A chink in a window covering, or a crack in a door admits the sunlight at such an angle as to strike the screen. 5. A brightly polished instrument in the orchestra catches the light and reflects it to the screen. 6. A stray light from the projection room, which is either in a direct line to fall upon the screen, or is being reflected upon it from the walls or a bright object, is a frequent trouble maker. 14. Gray, Flat Picture; No Contrast (a) — First, note if the print is at fault — that is, whether it is under-exposed or over-printed, etc. (b) — Dust may have settled on an oily lens surface, which should be cleaned. (c) — This may also be due to a dirty, smoky screen and to the fact that dust has settled upon the screen surface. In this case the screen surface should be cleaned thoroughly. (d) — Due to the density of the film the transmitted light has been decreased. Whenever this heavy part of the film is reached the light should be increased.
