A Film Recorder is a graphical output device for transferring digital images to photographic film. All film recorders typically work in the same manner. The image is fed from the computer by a raster file producing program. A film recorder will expose film with a beam of light output by a CRT (Lasergraphics) or a focused beam of light from an LVT (Light Valve Technology) recorder (Kodak). For color image recording on a CRT film recorder, the red, green, and blue channels are separately displayed on the same gray scale CRT, and exposed to the same piece of film through a filter of the appropriate color. (This approach yields better resolution and color quality than one could obtain with a color CRT.) The three filters are usually mounted on a motor-driven wheel. The filter wheel, as well as the camera's shutter, aperture, and film motion mechanism are usually controlled by the recorder's electronics and/or the driving software. Higher-quality LVT film recorders use a focused beam of light to write the image directly onto a film loaded spinning drum, one pixel at a time. The LVT will record pixel beyond grain.
