An optical printer is a Device consisting of one or more film Projector s Mechanical ly linked to a Movie Camera . It allows Filmmaker s to re- Photograph one or more strips of film. The optical printer is used for making Special Effects for motion pictures, or for copying and restoring old film material. Common Optical Effects include fade outs and fade ins, dissolves, slow motion, fast motion, and Matte work. More complicated work can involve dozens of elements, all combined into a single scene. Ideally, the audience in a theater should not be able to notice any optical printers work, but this is not always the case. For economical reasons, especially in the 1950s, and later in TV series produced on film, printer work was limited to only the actual parts of a scene needing the effect, so there is a clear change in the image quality when the transition occurs. The first, simple optical printers were constructed early in the 1920s. Linwood Dunn expanded the concept in the 1930s, and the development continued well into the 1980s, when the printers were controlled with Minicomputer s. In the late 1980s, digital special effects began to supplant optical effects. Since the mid nineties the conversion to digital effects has been virtually total. Optical printers today are primarily used for creating interformat blow ups, and simple effects, such as dissolves and titles. |
