                    Color correct using the eyedroppers
                </h1>
<!-- END PAGE TITLE -->
                <div><div class="section"><p>You
can use the eyedroppers in the Levels or Curves adjustment to correct
a color cast such as an unwanted tint from an excess of color (red,
green, blue, or cyan, magenta, yellow). It’s easier to color-balance
an image by first identifying an area that you want to be neutral
and then removing the color cast from that area. Depending on the
image, you can use one or all three of the eyedroppers. The eyedroppers
work best on an image with easily identified neutrals.</p>
<div class="note"><span class="notetitle">Note:  </span>The Set Gray Point Eyedropper tool&#160;<img src="images/P_SampleGrayPoint_Lg_N.png" /> is
used primarily for color correction and is unavailable when you
work with grayscale images.</div>
<p>For the best results, don’t
use the eyedroppers in images that require a large adjustment to
map a pixel to the maximum highlight or minimum shadow values. </p>
<div class="important"><span class="importanttitle">Important:  </span>Using the eyedroppers undoes any previous
adjustment you made in Levels or Curves. If you plan to use the
eyedroppers, it’s best to use them first and then fine-tune your
adjustments with the Levels sliders or Curves points. </div>
</div>
<ol><li class="stepexpand"><span>Identify
an area in the image that you want to be neutral gray. For example,
a paved road. </span> <div class="tip"><img src="images/tip_help.png" />Use a color sampler to mark a neutral area
so that you can click it with an eyedropper later.</div></li>
<li class="stepexpand"><span>Click the Levels or Curves icon in the Adjustments panel,
or choose Layer &gt; New Adjustment Layer, and then choose Levels
or Curves. </span> <div class="para"><div class="note"><span class="notetitle">Note:  </span> You can also choose Image &gt; Adjustments, and
then choose Level or Curves. You would complete the following steps
in either the Level or Curves dialog box. But keep in mind that
this method makes direct adjustments to the image layer and discards
image information. </div>
</div>
</li>
<li class="stepexpand"><span>In the Adjustments panel, double-click
the Set Gray Point tool&#160;<img src="images/P_SampleGrayPoint_Lg_N.png" />. In
the Adobe Color Picker, verify that the currently selected color
has identical R, G, and B values (for example, 128,128,128). </span></li>
<li class="stepexpand"><span>With the Set Gray Point Eyedropper, click the neutral
area that you identified in Step 1. This should reset midtones and
remove the color cast from the image.</span></li>
<li class="stepexpand"><span>If necessary, make final adjustments in the Adjustments
panel.</span> <p>If you specified new target colors for an eyedropper, Photoshop
asks whether you want to save the new target colors as defaults.</p>
