Photography, Motion Picture Film Cores and Spools, Performances, and Other Technical Information

摘要

The information contained in this document is intended to provide a means of more rapidly identifying most of the cores and spools used throughout the motion picture industry. No attempt has been made to identify all of the various items that are available, but rather to list those items most widely used. The purpose of this document is to present camera technical information and representations of the types of film cores and spools that are currently available on the open market. At the present time, only one company, Eastman Kodak, is supplying the test range industry with these film products. Specific technical information about these products appears in this publication. Additionally, information is included that may be of value to data reduction analysts. Also provided herein are representations of special cores and spools that are required specifically for high-speed camera use. These specially manufactured devices are designed to withstand the torque generated in high- speed camera operations. In addition to the identification of these cores and spools, an attempt has been made to provide technical information regarding flange focal distances, timing displacement, aperture openings for cameras, and light transmission for prism cameras.
