Figure 2.11
As you move the mouse pointer
around the image area, the RGB
values will change, showing you
the relative amount of each color
in that area of the image. Clicking
the mouse with the White Bal-
ance tool will set all three color
values to equal.
Note: Holding down the Alt/Option key will activate the Zoom Out tool and the Shift key will activate
the White Balance tool when Zoom, Move, or White Balance are active. Releasing the key will return you to
your regularly scheduled tool.
For more information on the White Balance tool and color temperature, see
Chapter 3, “RAW Conversion.”
Color Sampler Tool (Photoshop CS2 Only)
The Color Sampler tool lets you take up to nine measurements. The only real value
I can see in the Color Sampler is when you are using the Calibrate options, or identify-
ing a critical area for highlight and shadow detail adjustment. I'll cover this option in
Chapter 6.
Workflow Settings
The final area of the Preview window to look at is the Workflow Settings. As with the
Toolbar options, Photoshop has more options here (Figure 2.12) than in the version of
Camera Raw included with Elements.
Figure 2.12 (top) The Photoshop CS2 Workflow Settings area, located below the Preview window,
contains options for setting the bit depth, color space, resolution, and image size. (bottom) The Ele-
ments version of Camera Raw has fewer options than its big brother. You'll be able to set the bit
depth, preview size, and rotation, as well as highlight and shadow warnings.
