Correction Of Lens Peripheral Illumination And Aberrations - Canon EOS 5Ds Instruction Manual

Correction of Lens Peripheral Illumination and Aberration
3
Peripheral light fall-off is a phenomenon that makes the image corners
look darker due to the lens characteristics. Color fringing along subject
outlines is called chromatic aberration. This lens aberration and light
fall-off can be corrected. By default, Peripheral illumination and
Chromatic aberration correction are set to [Enable].
If [Cannot correct - no data] is displayed, see "Lens Correction Data"
on the next page.
Peripheral Illumination Correction
Depending on shooting conditions, noise may appear on the image
periphery.
The correction amount applied will be lower than the maximum
correction amount settable with Digital Photo Professional (EOS
software, p.521).
The higher the ISO speed, the lower the correction amount will be.
