Actually, there is one problem with this test. Detail. You said these
maneuvers might have my images look better than expected. In a smooth
gradient you might see what effect they have on posterization, but you
couldn't correlate it to the preservation of detail and sharpness that shows
in my images. IOW, blurring and softening moves are only effective at
"improving" images if they mitigate posterization WITHOUT destroying
sharpness and detail. Without some detail being processed alongside those
gradients I think it'd be hard to tell what positive or negative effect
those moves might have on a real image.
