Compensation

Available for the Local Entropy Minimization, Polynomial Third Degree, and Radial Basis Function filters, this parameter controls contrast after fitting for shading correction.

Effects of compensation for shading operations

Divide… The effect of selecting this parameter for shading operations is that contrast will be retained, particularly for like materials, after the shading operation is completed.

Subtract… In general, local contrast may be lost when this parameter is selected for shading operations.
