A visual representation of the exposure values of a digital image. Histograms are most commonly illustrated in graph form by displaying the light values of the image’s shadows, midtones, and highlights as vertical peaks and valleys along a horizontal plane. When viewing a histogram, the shadows are represented on the left side of the graph, highlights on the right side, and midtones in the central portion of the graph.
