How to Use a Camera’s Histogram: Part 1




“The ‘Histogram’ is a simple graph that displays where all of the brightness levels contained in the scene are found, from the darkest to the brightest. These values are arrayed across the bottom of the graph from left (darkest) to right (brightest). The vertical axis (the height of points on the graph) shows how much of the image is found at any particular brightness level… each of these 1 stop ranges contains within it just over 50 discrete brightness levels. (5X50=250 not 256)”. Source:
