title: Intermittent characteristic curves for Kodak 649F plates at 514.5 nm.
abstract: In a systematic study of sensitometric plate response for Kodak 649F, we have obtained various characteristic curves for intermittent exposures of laser light at 514.5 nm. Two different methods were used during the recording of specular exposures. We deduced typical values of the photographic parameters associated with these curves, many of which (T(A) - E; T(A) - logE; D - logE) are presented. The reciprocity law failure effects associated with many curves are discussed.
