  • Patent number: 6271908
    Abstract: A method of controlling a telecine machine to produce an exposure log of cinematographic film, comprising the steps of: using a telecine machine to generate video images from the cinematographic film, and displaying the video images on a monitor; generating timecode data for frames of the cinematographic film; generating image adjustment control data to adjust image parameters of the video images generated by the telecine machine so as to produce video images of a desired quality; using the image adjustment control data to generate exposure level information for frames of the cinematographic film; and logging in a film exposure logging system timecode data and exposure level information for frames of the cinematographic film so as to provide the exposure log. In one arrangement the cinematographic film is negative cinematographic film and the exposure log is used to generate exposure compensation printing settings for frames of the negative cinematographic film.
