Image Sharpness Evaluation of Motion-Picture Prints in Various Formats Made from 16mm Originals

John C. Norris

Color release motion-picture prints in 35mm, 16mm and super-8 formats are being produced from 16mm originals. An evaluation is made of the image sharpness achieved in the prints, using both subjective testing and modulation transfer techniques. The sharpness of 35mm enlargements of 16mm Eastman Ektachrome Commercial Film 7252 originals made through 35mm internegatives is comparable to that obtained through conventional duplicate negative and reversal duplicate negative stages that start with 35mm color negatives. This enlargement from the 16mm reversal original is superior to enlargements of 16mm color negatives through the 35mm duplicating stages. Super-8 prints made with the current reversal original, internegative and print materials surpass the image quality attainable in 16mm prints made with the preceding generation of color films.
