Black / White Correction

Sometimes your scan results might not cover the full gray spectrum. This filter will aid you to find the best cut off values to receive the optimal results. All values larger or smaller than the given threshold will be mapped to clean white or black. The grayscales between will be recalculated to make use of the full spectrum.
