Changing Gamma Curve Values
With the Gamma curve you can change the mid-tones of colours to
increase the contrast between colours, and enhance the overall image.
When you increase the Gamma value, light colours are made lighter, and
dark colours are made darker.
For example, if you are scanning a photograph that has many dark tones,
simply adjusting the brightness and contrast may not improve the image
as effectively as adjusting the Gamma value.
To adjust the gamma value of an image:
1. On the Tone tab, click the Gamma button.
2. To adjust the gamma value for a particular colour, select the colour
from the Channel list box. Otherwise, leave the channel set to Master.
