Click on

in the Image Correction window.

When the Tone curves/Histogram Correction button is clicked, the Tone Curves/Histogram
Correction dialog box is displayed.
The Tone Curves dialog box allows you to change the tone curves and to directly correct the output
value.
The Histogram dialog box allows you to specify the input and output area from the information
included in the scanned film and to then correct the image. This dialog box displays also the
histogram of the image area inside the cropping frame in each RGB color. The level is indicated in
256 color steps (0 to 255) from the left to right.
The tone curves and histogram are linked to each other so that when the tone curve is corrected,
the histogram is automatically corrected.
