About the Image Histogram Tool

Frequently Asked Questions
What does a "clipped" histogram mean?+
If a channel piles up sharply against the left or right edge of the chart, detail is being lost to pure black or pure white (over/underexposure) in that channel.
Why do the red, green, and blue lines look different from the luminance line?+
Luminance weights green more heavily than red and blue to match human perception of brightness, so it can look quite different from any single color channel.
Is this useful for anything besides photography?+
Yes — designers use it to check color balance, and developers use it to verify image processing pipelines are working as expected.
