Abstract:

The basic Concurrent Photon Amplification CPA technique has been modified and optimized for two Kodak color negative films Kodak Kodacolor-II and Kodak 2445. Speed increases of up to 8 times 3 stops have been achieved with good color balance and good print contrast. A CPA capability for Kodacolor-II and a range of black and white films from Kodak Pan-X to Kodak Tri-X was installed into two Pentax Spotmatic II, 35mm cameras. Power and controls for the CPA circuits are contained in a detachable case which fastens neatly underneath the camera bottom without obstructing any of the camera functions and provides a single lever activator of the CPA lamps and release of the camera shutter.
