Shading correction
Owing to technical circumstances, the interaction of recorded objects with
one another, optical effects and lighting non-homogeneities may occur in
the images.
Because these effects are normally not desired, they should be eliminated as
far as possible in subsequent image editing. The camera has automatic shad-
ing correction to do this.
Provided that a shading image is present in the camera, the on/off bit can
be used to enable shading correction.
The on/off and ShowImage bits must be set for saved shading images to be
displayed.
Note
L
Always make sure that the shading image is saved at the
highest resolution of the camera. If a lower resolution is cho-
sen and ShowImage is set to true, the image will not be dis-
played correctly.
