Shading Correction

The interactions between objects, illumination, and the camera lens might
lead to a non-uniform flatfield in brightness. Shading describes the non-
uniformity of brightness from one edge to the other or center towards
edge(s).

This shading can be caused by non-uniform illumination, non-uniform
camera sensitivity, vignetting of the lens, or even dirt and dust on glass
surfaces (lens).

Shading correction is a procedure to create a flatfield image out of a
non-uniform image regardless of the reasons of the non-uniformity.
Before doing shading correction, make sure your lens is clean and in
perfect condition. If the lens is not clean or the lighting not uniform, the
algorithm tries to compensate these as well – resulting in a wrong shading
table and visible artifacts, loss of details or local noise in the final image.
