The Effect of Camera Exposure on the Tone-Reproduction Quality of Motion Pictures
A psychophysical study has been made of the relationship between the tone-reproduction quality of a positive motion-picture screen image and the camera exposure for the corresponding negative throughout a series of negative exposures for each of sixteen outdoor scenes and eight indoor scenes. A description is given of the method used for obtaining psychometric data, and curves are presented showing the relationship between screen image quality and the logarithm of the camera exposure. The use of these curves in determining exposure latitude, speed and exposure index is discussed.
