Claim One:
1. A method of digital photofinishing comprising; producing a digital color image in printing or other densities of a color image captured on alternative capture photographic media; first mapping said printing or other densities of said alternative capture photographic media to the printing densities that would have been obtained for reference color photographic media; rotating said digital image to "t space", applying a tone scale look up table produced by a contrast normalization algorithm to said rotated digital image and rotating said digital image from said "t space"; processing said digital color image with a scene balance algorithm to produce a processed digital color image; second mapping said processed digital color image thorough a hard copy media characteristic curve to produce mapped digital color image mapped to print densities of said hard copy media; sharpening said mapping digital color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing said sharpened digital color image onto hard copy media.
