TELECINE REFERENCE ELEMENT, SYSTEM, AND METHOD FOR PROVIDING SCENE EXPOSURE INFORMATION

摘要

A method of transferring a scene recorded on photographic negative film to video using a telecine is disclosed comprising the steps of: a) setting up the telecine so that predetermined waveform readings are obtained for a reference element comprising at least one gray scale portion comprising density patches corresponding to three known density values; b) storing the telecine set-up settings; c) loading a scene on photographic negative film into the telecine wherein the scene includes a gray card; d) using the stored telecine settings to effect transfer of the scene to video; e) determining red, green and blue video voltages for the gray card; and f) converting the red, green and blue video voltages to Transfer Points between 0 and 50 to provide exposure information for the scene. The reference element preferably comprises density patches which correspond to densities obtained in a color negative film after correctly exposing the film to a target comprising a 3 % reflectance black, an 18 % reflectance gray and a 90 % reflectance white region, and standard photographic processing. Advantageously, the gray scale portion fills a full frame on the element. In a preferred embodiment of the reference element, the gray scale portion is horizontally arranged thereon. The red, green and blue video voltages are converted to Transfer Points between 0 and 50 to provide exposure information analogously to Printer Light values obtained for dailies or test print films.
