Ghosting: Difference between revisions

'''Ghosting''' occurs when the projector [[shutter]] is closing either too early or too late. The function of the shutter is to hide the film as it is being pulled down by the [[intermittent]] or [[claw]], and reveal it while it is sitting still in the gate. When the shutter is out of time, ghosting occurs and the audience sees a little bit (or in some cases, a lot!) of the frame being pulled down. If ghosting appears above the image, the shutter is closing late. If ghosting appears below the image, the shutter is closing early. This is especially noticeable on films with subtitles, or in scenes with lamps in a dark room, for example. Because the image is being "smeared," it reduces perceived sharpness. Very bad!
