To adjust the color settings:

1.From the Channel drop-down menu, choose the individual color (Red, Green, or Blue) that you want to use as the basis for adjusting the image, or choose All to adjust them together.

2.From the Edit Style drop-down menu, choose the type of color editing that you want to use:

■Gamma—the response curve changes as you change the gamma setting; you can also change the saturation and hue settings.

■Freestyle—you can drag points and sections of the response curve to create interesting and unusual color effects. Put the pointer on the curve and drag left, right, up or down. The image changes its colors in response to the new curve. The x and y numbers at the bottom of the response curve indicate the exact position of the pointer on the curve. The Gamma slider remains fixed when you use the Freestyle option.

3.Drag the Gamma, Saturation, and Color Hue sliders to the left to decrease the settings or to the right to increase the settings.

You can also type a number directly into the setting boxes, or click the up and down arrows next to the boxes.

4.Click Reset to return the settings to their original numbers.

The upper Reset button is for the gamma setting, the lower one is for saturation and hue.

5.To save the settings of a response curve, click Save.

Saving is available for settings created with the Freestyle editing option so you can load and reuse the exact settings on other images. This is especially helpful for complex Freestyle response curves.

A dialog box appears that lists the names of previously saved settings. Type a name for your new settings and click OK.

6.To reuse a saved response curve setting, click Load.

A dialog box lists the names of your previously saved settings. Select the one you want and click OK.
