How To...
|
Use Gamma to adjust the gamma for the entire image. This
setting affects the tone values of scanned images. To adjust the image
gamma, you can specify a Gamma value between 0.01 and 5.00. A higher gamma value
yields an overall lighter tone of the color channels you make
adjustments for. |
- Drag the slider to set the gamma value. Dragging to the left
decreases the gamma value and to the right increases it. The changes
you make with the slider are automatically displayed in the related
box, and vice versa.
- You can also use spin buttons, or type a certain value in the
Gamma box to adjust the image gamma. To increase the gamma
value, click an arrow pointing up. To decrease gamma value, click an
arrow pointing down.
When entering a value in the Gamma box,
specify a value between 0.01 and 5.00. Ordinarily, good results can be obtained from your scanner
using the default value of 1.
