Vertical Shading Adjustment
0 Adjustment of white shading is needed when
you have changed the lens.
0 Although white balance may be appropriate at
the center of the image, this may not be the case
at the top and bottom areas.
If this is the case, the image will appear greenish
or yellowish. This phenomenon is due to the
characteristics of the lens. The process of
correcting this phenomenon is referred to as
vertical shading adjustment.
0 Perform this process after adjusting the white
balance.
Setup Prior Adjustment
