Check Image Quality with Histogram

You can use the Adjust/Enhance > Histogram menu item to open the Histogram dialog.

The Histogram graph shows the distribution of pixel intensity levels. The horizontal axis represents each of the

intensity levels (0-255). The vertical axis shows the number of pixels with that intensity level. The figure below shows

that the image doesn't have enough information in the shadow areas (left part of graph). The middle part of the

graph represents the intensities in the mid-tone ranges. The right part of the graph displays highlights information.

You can see the distribution of intensity in each channel by clicking the drop down arrow in the Channel box to select

one of the RGB values: Red, Green, or Blue from the pull down list.

The statistical information appears at the bottom of the dialog. You can also obtain the statistical information of a

certain range of intensities by clicking on the graph and drag the left and right small triangles at the bottom range bar

to select a range.
