ABSTRACT:
A method of digital photofinishing comprising the steps of: producing a digital color image in optical printing densities of a color image captured on photographic media; increasing the under-exposure gamma of the digital color image using a media under-exposure gamma adjustment algorithm; processing the under-exposure gamma adjusted digital color image with a scene balance algorithm to produce a balanced digital color image; mapping the balanced digital color image through a hard copy media characteristic curve to produce a balanced digital image mapped to print densities of the hard copy media; sharpening the mapped balanced digital color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing the sharpened digital color image onto hard copy media.
