摘要：
A method for calibration and/or compensation in transference of digital and/or analogue motion pictures to a photosensitive material comprises exposing a section of a photosensitive material by modulating light from a light source and imaging the modulated light onto the photosensitive material, develop the section of the photosensitive material, measure the characteristics of the developed film while illuminated by the said light source, and adjusting the light source and/or light modulation according to the measurement. By using the same light source for exposing and measuring the film, good reproducibility can be achieved, as well as a reliable basis for the adjustments.
