Histogram

The histogram provides a visual graph showing the distribution of values throughout your image. It's a powerful analytical tool used by photographers and artists to understand tonal balance.

How it works

The histogram displays a graph where the horizontal axis represents value (from black on the left to white on the right), and the vertical axis shows how many pixels exist at each value level. A peak indicates many pixels at that value.

Why it's useful

Reading the histogram helps you:

  • See the overall tonal range of your image at a glance
  • Identify whether your image is predominantly light, dark, or balanced
  • Spot gaps in the value range
  • Understand the mood and contrast of the composition

Tips for use

A histogram weighted toward the left indicates a low-key (dark) image, while one weighted to the right shows a high-key (light) image. Images with peaks at both extremes tend to have strong contrast and drama.
