Lens Aberration
Some lens characteristics could cause the periphery of images shot to become darker than the center, or cause the subject to be distorted. In such cases, you can use the lens aberration correction function of Digital Photo Professional.
Using this function, you can improve the following phenomena, which cannot be completely eliminated in the lens structure, to make images that are closer to what you intended.
Phenomena that can be corrected:
・Diminished peripheral illumination (the amount of light at the periphery of an image)
・Distortions (distorted lines)
・Chromatic aberration (color fringing that occurs in the periphery of an image)
・Color blur (blue or red color blur that sometimes occurs at the edge of the highlighted area of an image)
Caution
Please see Lenses compatible with the Lens Aberration Correction feature of Digital Photo Professional Ver. 4.4.0 for information on cameras and lenses compatible with the lens aberration correction function in the latest version of Digital Photo Professional.
