Original language description
One of the important visual perception discoveries made by Mach is now known as Mach’s band effect. He observed and recorded this visual phenomenon in 1860s. The effect is observed in the vicinity of the boundaries that separate regions of differing illumination or tone. The result is the perception of bright or dark bands in the boundaries. The following example shows the effect of placing an identical set of five tonal bars next to each other, once with a side touching and then with some gap between them. The Mach band effect is visible in the right hand image where the bars are in contact. In this case, the brain exaggerates the difference between bars when they are touching and perceives the color of a physically uniform bar lighter where it touches a darker neighbor and darker where it touches a lighter neighbor. This results in increased perceived differences between the bars.
