Claims14
A method of forming a colored photographic image, the method comprising:
- receiving a panchromatic black and white photographic emulsion having encoded therein color domain information solely from an ultraviolet wavelength portion of an electromagnetic spectrum (EM) of an image captured through a color filter array adapted to block visible wavelength portions of the EM and allow the ultraviolet wavelength portion to pass therethrough;
- and
- processing the black and white photographic emulsion with a reversal process to produce a positive color transparency.
