Histogram
Also known as: exposure histogram, luma histogram
A graph that shows how many pixels fall at each brightness level, from black on the left to white on the right, giving an objective view of exposure.

What it means
A histogram counts the pixels in an image by brightness and draws them as a graph. Dark tones pile up on the left, midtones in the middle and bright tones on the right. The shape tells you at a glance whether a shot is too dark, too bright or well balanced.
It is far more reliable than judging a small camera screen in sunlight. A screen can look bright and contrasty while the actual image is underexposed, or vice versa. The histogram does not lie about clipped highlights or crushed shadows.
Many phones, drones and action camera apps can show a live histogram while recording, and editing software offers it too.
How it works in practice
For most scenes, aim for a histogram that spreads across the range without large spikes jammed against either edge. A spike on the right edge means part of the image is pure white, and on the left edge pure black.
Bright scenes like snow should sit to the right, and dark scenes like night streets to the left. That is normal, as long as the important detail does not touch the edges. Adjust with exposure compensation or manual settings until the shape fits the scene.
In editing, the histogram and its cousin the waveform help you match clips and set black and white levels consistently.
What to watch out for
A histogram shows the whole frame, not the subject. A small face in a large sky can be badly exposed while the graph looks fine. Combine it with your eye, or use spot measurement or zebras for the subject.
Some cameras show a histogram of the processed preview, not the recorded file, especially with flat or log profiles. Learn how your camera behaves with a few test shots.
There is no single correct shape. Chasing a perfect bell curve for every scene leads to flat, gray footage. Use the histogram as a guide to avoid clipping, not as a target.
How RawClip handles it
RawClip uses your clips as recorded and does not adjust brightness. Checking the histogram while filming helps you bring home well-exposed footage, and the AI builds your highlight from the strongest moments.
