Color Shading Correction

Color (shading) variations between the center and edges of the frame can be adjusted separately for each corner.

To use color shading correction, follow the steps below.

1 Rotate the command dial to choose a corner. The selected corner is indicated by a triangle.

2 Use the selector to adjust shading until there is no visible difference in color between the selected corner and the center of the image. Press the selector left or right to adjust colors on the cyan–red axis, up or down to adjust colors on the blue– yellow axis. There are a total of 19 positions available on each axis.

R To determine the amount required, adjust color shading correction while taking photos of blue sky or a sheet of gray paper.

Peripheral Illumination Correction Choose from values between –5 and +5. Choosing positive values increases peripheral il- lumination, while choosing negative values reduces pe-

ripheral illumination. Positive values are recom- mended for vintage lenses, negative values to create the effect of images taken with an antique lens or a pinhole camera.
