A method for producing an extended color gamut luminance-chrominance digital image from a captured digital image includes determining an estimate of the colors of the captured digital image of an original scene and further processing to produce an extended range output RGB image value including values outside the range that can be displayed on the output image display device, and producing an extended color gamut luminance-chrominance digital image by transforming the extended range output RGB image values to a luminance-chrominance representation.
