3 Correction of Lens Peripheral Illumination and Aberrations 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. And image distortion due to lens characteristics is called distortion. These lens aberrations and light falloff can be corrected. By default, Peripheral illumination and Chromatic aberration correction are set to [Enable], and Distortion correction is set to [Disable]. Peripheral Illumination Correction 1 Select [Lens aberration correction]. Under the [z1] tab, select [Lens aberration correction], then press . 2 Select the setting. Check that [Correction data available] is displayed for the attached lens. Select [Peripheral illumin.], then press . Select [Enable], then press . 3 Take the picture. The image will be recorded with the peripheral illumination corrected. 104

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. And image distortion due to lens
characteristics is called distortion. These lens aberrations and light fall-
off can be corrected. By default, Peripheral illumination and Chromatic
aberration correction are set to [
Enable
], and Distortion correction is set
to [
Disable
].
