Digital camera images with under/over exposure and/or color cast can be easily corrected using image processing tailored to the specific tone profile of each digital camera, yielding images that closely resemble those shot under optimum conditions. Correction of saturation and color balance usually requires complicated adjustment of tone curves, but this technology now permits simplified enhancement of saturation and color balance to allow for variations in shooting conditions for all compatible digital camera models. This sophisticated technology maximizes the color reproduction design and analysis expertise amassed during the era of film photography.
When images are overexposed, blown-out highlights are not corrected. When images are underexposed, noise in shadow portions may be conspicuous under certain shooting conditions.
