TRAVEL GHOST 121 2. "Travel Ghost" Intermittently (a) — The shutter revolving device may have a worn part which allows an occasional slip or "play." This should be examined and corrected. 3. "Travel Ghosf Pronounced (a) — The master blade of the shutter may not be wide enough. (b) — The intermittent may not be adjusted to move and hold the film in its proper relation to the movement of the shutter and its action of cutting off and restoring the light to the screen. (c) — Shutter not properly adjusted. 4. "Travel Ghost"; Picture Seems to "Crawl Up" on Screen (a) — The picture will "crawl up" on the screen due to loose or worn framing device, which should be tightened to overcome this trouble. 5. Uneven Light, Noticeable Most on Plain Screen (a) — This may be due to a poor "screeningout" (elimination), of daylight or reflected light. This does not show enough to form a glare spot, but it makes a difference in the lighting of the screen surface and is most apparent when no projector light is thrown on the screen surface.
