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.
