ABSTRACT:
A method of digital photofinishing comprising the steps of: producing a digital color image in printing densities of a color image captured on alternative capture photographic media; first mapping the printing densities of the alternative capture photographic media to the printing densities that would have been obtained for reference color photographic media; processing the mapped digital color image with a scene balance algorithm to produce a processed digital color image; second mapping the processed digital color image through a hard copy media characteristic curve to produce a mapped digital color image mapped to print densities of the hard copy media; sharpening the mapped digital color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing the sharpened digital color image onto hard copy media.
