An Electronic Luminous Footage Counter
Roger J. Snowdall, William D. Hedden · Journal of the SMPTE · 1965
In the laboratory inspection of answer prints, it is frequently desirable to indicate timing and color corrections to improve specific scenes. Locating scenes in long shows, or in those with numerous short scenes, has been facilitated by an electronic luminous footage counter developed at Calvin Productions. This counter may be operated with a modification of a conventional commercial projector. The construction and operation of this footage counter are described and similar uses with selsyn operation for sound recording are discussed.
