Like the Highlight/Shadow levels, the Curves feature also adjusts the
range of midtone colors on an image. However, with the Curves feature
you can set the gamma individually to adjust midtone levels without
losing details from the lightest or darkest areas.
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.
