By looking at the histogram for a specific image a viewer will be able to judge the entire tonal distribution at a glance.
A histogram is a representation of tabulated frequencies, shown as adjacent rectangles or squares (in some of situations), erected over discrete intervals (bins), with an area proportional to the frequency of the observations in the interval.
