Abstract
A method for modifying a digital image having color values with an extended color gamut comprising the steps of representing the extended color gamut digital image with a limited color gamut digital image and one or more associated residual image(s) representing a difference between the extended color gamut digital image and the limited color gamut digital image; specifying one or more desired image modification(s) to be applied to the extended color gamut digital image; and modifying the limited color gamut digital image and the residual image(s) to form a modified limited color gamut digital image and one or more modified residual image(s) in response to the specified desired image modification(s).
