Abstract:
A method of digital photofinishing comprising the steps of:producing a digital color image having colorimetric tristimulus values describing a color transparency media from a color image captured on color transparency media; first transforming said digital color image having colorimetric tristimulus values describing color transparency media to a digital color image having colorimetric tristimulus values describing a reflection print; second transforming said digital color image having colorimetric tristimulus values describing a reflection print into digital code values representative of said color image for printing by a digital color printer using a combination of 1D and 3D look up tables; sharpening said transformed digital code values representative of said color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing said sharpened digital color image onto reflection media.
