Abstract
A novel method and apparatus is disclosed for electronically sensing a negative and a positive in a novel integral film structure of the instant development type using light of different wavelengths so as to produce reflected light from the negative and the positive which are indicative of the luminance characteristics and the chrominance characteristics of the image. The novel integral film structure has a filter which allows the negative to be scanned. Specifically, the filter transmits incident radiation in the range of wavelengths other than a select range of wavelengths to which silver halide emulsion layers are sensitive and blocks the transmission of radiation in the range of wavelengths to which the silver halide emulsion layers are sensitive.
