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 
on the 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
5.Adjust the tones by selecting and dragging the triangles at the bottom of the histogram until the desired effect is achieved.
