Under SELECT>COLOR RANGE, one can then select Shadows, Midtones, or Highlights.

From doing this on an image with a grayscale in it, it seems that each of the ranges above is 1/3 the total range of 0 to 255.

I do not see any way to change things, where I would like set the boundaries. Is there a way for the user to define different given ranges to be used?
