Picker
The Picker lets you pick a known neutral gray shade in your image
and adjusts it to a closer, truer gray. The grays in an image may
have a particular color cast which can be verified through the color
information in the Info window. A gray that tends towards a reddish
tint, for instance, will have its R value skewed higher than the G and
B values. By using the Picker on a gray area, the gray is adjusted so
that the RGB values become approximately equal.
Saturation bar
This lets you change the intensity of the hues (colors) in your image.
Use Saturation selectively, because increasing saturation will
increase the intensity of all hues in the image.
Using the Color Wheel:
1. To change the hue of an image, move the pointer in the color
wheel to its new color position in the wheel.
2. To change the saturation of an image, drag on the saturation
slide bar. Dragging the slide bar to the left decreases
saturation; dragging it to the right increases saturation.
3. Use the Angle, Radius, and Picker as necessary.
4. Click an action button. For more details, see the section
Action buttons.
