Advanced Control Panel > Settings window
Tone Curve tool
The
Tone Curve
tool lets you adjust the tonal range of an image. However,
instead of making adjustments using just three variables (highlights,
shadows, and midtones), you can adjust any point along the 0-to-255 scale
(for 8-bit images; 0-to 4096 scale for 12-bit images). The Tone Curve tool
applies to grayscale and all color images and is not available for line art or
halftone scan modes.

How to Read the Curve
The Curve shows the relationship of the brightness
changes across the middle pixels between the
resulting image and the original. When you open
the Curves dialog box, the line on the graph is
diagonal because the Input and Output values are
the same.
When the curve is moved up or down, the
relationship between input value and output value
changes accordingly.
●
In areas where the curve is moved down,
pixels in that portion of the image are
darkened.
●
In areas where the curve is moved up,
pixels in that portion of the image are
lightened.
