Wertheimer set out the laws of grouping in 1923. Edgar Rubin published his ambiguous vase figure in 1915 to demonstrate the figure and ground decision. The Gestalt tendency to adopt the simplest available organisation is called Prägnanz. The exaggerated light and dark edges the eye adds at a tonal boundary are Mach bands.
The last blank is the one that changes studio practice. Mach bands are added by the eye at every tonal boundary, so a perfectly even gradient still shows ridges, and a painter who chases those ridges with more blending is repainting something that was never in the paint.
