Question

Quizplus · Accepted Answer

The Mach band demonstration is a compelling illustration of contrast enhancement. Mach bands are the illusory dark and light bands seen at the edges of two side-by-side grey areas, which make the areas appear more different in brightness than they really are. This effect is due to lateral inhibition in the visual system, which enhances the contrast between adjacent areas with different brightness levels.
