About Image Histogram

Image Histogram is an analytical tool for photographers and designers. It displays a graphical representation of the tonal distribution in a digital image. It plots the number of pixels for each tonal value, helping you understand exposure and color balance.

How to Use?

• Upload an image to analyze.
• The tool generates histograms for Red, Green, Blue, and Luminance channels.
• Hover over the graph to see specific values if supported.

Features

• RGB Channels: View distribution for individual color channels.
• Luminance: See the overall brightness distribution.
• Exposure Check: Quickly identify underexposed (clipping shadows) or overexposed (clipping highlights) images.
• Browser-Based: Instant analysis without uploading to a server.

FAQ

What does the histogram tell me?

If the graph is bunched up to the left, your image is dark (underexposed). If it's bunched to the right, it's bright (overexposed). A balanced image typically has a spread across the entire width.

What is "clipping"?

Clipping occurs when the graph hits the left or right edge. This means detail has been lost in the pure blacks or pure whites of the image.

Can I edit the histogram?

This is a viewer tool. To change the histogram, you need to use an image editor (like our Exposure or Gamma tools) to adjust the image itself.
