To adjust the gamma curve:
1. Click the Curves button.
The dialog box that opens shows a plot of the gamma. The
gamma of the original image is represented by a straight line
from the lower left to upper right corners. Changing the straight
line to a curve changes the gamma setting for the midtones on
the original image.
2. From the Channel drop-down list, choose RGB to adjust the
gamma of all the channels together, or choose a single channel
if available.
3. Drag the line up or down to set a new gamma.
The input and output values represent values on the horizontal
and vertical axes for the new gamma setting. Click the Curve
or Line button to see the display as a smooth curve or a line.
You can drag the line at multiple points.
4. Click Preview to see the effect of the new settings on the
preview image.
5. Click Reset to reset the levels to their original values.
6. Click OK when the levels are what you want.

Color Balance

The color balance refers to the relative amounts of the three
primary colors in an image. By adjusting the color balance you can
sometimes compensate for an image with too much or too little of a
color.
