How to read a histogram

A histogram describes brightness distribution, not composition quality. The left represents shadows and the right highlights.

Core principle

A histogram describes brightness distribution, not composition quality. The left represents shadows and the right highlights.

Practical workflow

Highlight warnings and RGB histograms help reveal clipping in individual color channels.

1. Define the image goal and working conditions.
2. Choose baseline settings and make a test frame.
3. Check focus, histogram and critical image areas.
4. Record the settings that worked and why you changed them.

What to verify before finishing

A correct histogram is not always centered: night scenes are naturally dark and snow scenes naturally bright.

Do not treat a single rule as a guarantee. Conditions, equipment design and output size change the requirements. Record settings and conclusions in the AparatTo planner.
