Editing tools

Basic editing tools in DPP include brightness, white balance and picture style adjustment and the adjustments for contrast, saturation and sharpness. The latest version adds sliders for controlling contrast more precisely in highlight and shadow areas. There is also a noise reduction tool which has separate settings for luminance and chrominance noise. Lens aberration tool can be used for correcting the effects of physical lens imperfections like peripheral illumination, distortion and chromatic aberration. Aberration tool only works with RAW files that were taken with compatible cameras and lenses.
