I am trying to use adaptive gradient removal on image PIC1.
In preview it looks great (PIC2), but when I click OK the image gets wierd (PIC3).

Hi, the dynamic range of the image is too small (423..450, only 27 steps!).
You may solve converting the image to floating point before applying the filter (the preview is in floating point).
Or, to continue working with integer numbers, you may multiply the image by 10 or more.

Converting to floating point solves the problem.
Thank You!
