This paper discusses the advantages of applying the Concurrent Photon Amplification (CPA) speed enhancement techniques, to small-format camera systems, to obtain increased film speed without loss of resolution. The increase in dynamic range and exposure latitude for any given film, provided by the CPA technique is also discussed. Sample photographs are shown that demonstrate the results obtained using Concurrent Photon Amplification (CPA) with various 35 mm and 70 mm black and white films.
