These examples dramatically show the difference between regular Gaussian Blur and AcuBlur. (AcuBlur is an advanced form of gaussian blur)

After these images were selected and moved to a new transparent layer both were blurred a similar amount. The edges of the regular gaussian blurred image deteriorated and were blurred away but the AcuBlurred image retained solid edges.

Notice that it took ten applications of AcuBlur, at full strength, to get a similar amount of blurring as regular gaussian blur at 3.5. GoldPanner "AcuFilters" were designed to work with photo/images using much finer settings than most filters.
