An image histogram is a graph showing the distribution of pixel intensities (0–255) in an image. It helps you understand exposure, contrast, and tonal range at a glance.
A cumulative histogram shows the running total of pixel counts. It is used in histogram equalization — a technique to improve image contrast by redistributing intensity values.
