Curves Dialog Box
Using the curves dialog box, any point along the tone curve can be adjusted for all color tones (Master) or
for the individual RGB channels. Changing the shape of the tone curve, changes the output level for each
corresponding input level.
Pulling up on the tone curve increases the output level, making the image lighter and the color more red,
green, or blue. Pulling down on the curves decreases the output level, making the image darker and the
color less red, green, or blue.
1. Click on the check box of the curve you want to adjust.
• The Master curve controls the output brightness of the scanned image.
• The R, G, and B curves control the output color levels of the scanned image.
2. Click on and drag the portion of the curve you want to change. The change will be reflected in the preview
image.
• Pull the curve up to increase the output level.
• Pull the curve down to decrease the output level.
3. Click on the Reset button to return the selected curve to its default setting.
