Adjusting the Histogram Manually
Follow these steps to make manual adjustments to the
tones in an image:
1. Preview the image.
2. Click on the Histogram tool icon
EPSON Perfection 600 main window. The
histogram dialog box appears.
3. Check the Selection Area Only box. Any changes
you make affect only the selected area.
4. Select a color to adjust.
There are three color channels that make up the full
spectrum of color: red, green, and blue. If there is
too much of a particular color in an image, select
that color from the Channel drop-down list.
Otherwise, leave the Channel set to Master (all).
5. Adjust the tones by selecting and dragging the
triangles at the bottom of the histogram until the
desired effect is achieved.
