ABSTRACT:
A method for processing a digital image comprising the steps of: providing a digital image from an original image on exposed photographic media; determining the exposure of the original image; and based on the exposure, sharpening the digital image using an image sharpening system. A method of processing a digital image comprising the steps of: providing a digital image from an original image on exposed photographic media; determining the type of the photographic media and magnification to produce the final image; and based on the type of the photographic media, sharpening the digital image using an image sharpening system. A method of processing a digital image comprising the steps of: providing a digital image from an original image on exposed photographic media and magnification to produce the final image; determining the type of the photographic media; determining the exposure of the original image; deriving the print grain index from the media type, magnification, and exposure of the original image; determining the sharpening level of the digital image based on the print grain index; and sharpening the digital image using an image sharpening system.
