Sets the white balance to compensate for a green or magenta tint. Decrease Tint to add green to the image;

increase Tint to add magenta.
To adjust the white balance quickly, select the White Balance tool
that should be a neutral gray or white. The Temperature and Tint properties adjust to make the selected color exactly
neutral (if possible). If you're clicking whites, choose a highlight area that contains significant white detail rather than a
specular highlight. You can double-click the White Balance button to reset White Balance to As Shot.
Adjust tone in Camera Raw
You adjust the image tonal scale using the tone controls in the Basic tab.
When you click Auto at the top of the tone controls section of the Basic tab, Camera Raw analyzes the camera raw
image and makes automatic adjustments to the tone controls (Exposure, Recovery, Fill Light, Blacks, Brightness, and
Contrast).
You can also apply automatic settings separately for individual tone controls. To apply an automatic adjustment to
an individual tone control, such as Exposure or Recovery, press Shift and double-click the slider. To return an
individual tone control to its original value, double-click its slider.
When you adjust tone automatically, Camera Raw ignores any adjustments previously made in other tabs (such as
fine-tuning of tone in the Curves tab). For this reason, you should usually apply automatic tone adjustments first—
if at all—to get an initial approximation of the best settings for your image. If you are very careful during shooting
and have deliberately shot with different exposures, you probably don't want to undo that work by applying
automatic tone adjustments. On the other hand, you can always try clicking Auto and then undo the adjustments if
you don't like them.
Previews in Bridge use the default image settings. If you want the default image settings to include automatic tone
adjustments, select Apply Auto Tone Adjustments in the Default Image Settings section of the Camera Raw prefer-
ences.
Note: If you are comparing images based on their previews in Bridge, you may want to leave the Apply Auto Tone Adjust-
ments preference deselected, which is the default. Otherwise, you'll be comparing images that have already been
adjusted.
As you make adjustments, keep an eye on the end points of the histogram, or use the shadow and highlight clipping
previews.
While moving the Exposure, Recovery, or Blacks slider, hold down Alt (Windows) or Option (Mac OS) to preview
where highlights or shadows are clipped. Move the slider until clipping begins, and then reverse the adjustment
slightly. (For more information, see "Preview highlight and shadow clipping in Camera Raw" on page 94.)
• To manually adjust a tone control, drag the slider, type a number in the text box, or select the value in the text box
and press the Up or Down Arrow key.
• To reset a value to its default, double-click the slider control.

adjustment of +1.50 is similar to widening the aperture 1-1/2 stops. Similarly, an adjustment of -1.50 is similar to
