                    Fine-tune tone curves in Camera Raw
                </h1>
<!-- END PAGE TITLE -->
                <div><div class="section"><p>Use the controls in the Tone Curve tab to
fine-tune images after you’ve made tone adjustments in the Basic
tab. The tone curves represent changes made to the tonal scale of
an image. The horizontal axis represents the original tone values
of the image (input values), with black on the left and progressively
lighter values toward the right. The vertical axis represents the
changed tone values (output values), with black on the bottom and
progressing to white at the top. </p>
<p>If a point on the curve
moves up, the output is a lighter tone; if it moves down, the output
is a darker tone. A straight, 45‑degree line indicates no changes
to the tone response curve: the original input values exactly match
the output values.</p>
<p>Use the tone curve in the nested Parametric
tab to adjust the values in specific tonal ranges in the image.
The areas of the curve affected by the region properties (Highlights,
Lights, Darks, or Shadows) depend on where you set the split controls
at the bottom of the graph. The middle region properties (Darks and
Lights) mostly affect the middle region of the curve. The Highlight
and Shadows properties mostly affect the ends of the tonal range. </p>
</div>
<div class="p"><span><img src="images/dingbat.png" />&#160;To adjust tone curves, do any of the following:</span> <ul><li><p>Drag the Highlights, Lights, Darks, or Shadows
slider in the nested Parametric tab. You can expand or contract
the curve regions that the sliders affect by dragging the region
divider controls along the horizontal axis of the graph.</p>
</li>
<li><p>Drag a point on the curve in the nested Point tab. As you
drag the point, the Input and Output tonal values are displayed
beneath the tone curve.</p>
</li>
<li><p>Choose an option from the Curve menu in the nested Point
tab. The setting you choose is reflected in the Point tab, but not
in the settings in the Parametric tab. Medium Contrast is the default
setting.</p>
</li>
</ul>
