The graph in the Tone Curve panel of the Develop
module represents changes made to the tonal scale of a photo. The
horizontal axis represents the original tone values (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 lighter values progressing to white
at the top. Use the tone curve to tweak the adjustments you make
to a photo in the Basic panel.
 Develop module Tone Curve panel If a point
on the curve moves up, it becomes a lighter tone; if it moves down,
it becomes darker. A straight, 45-degree line indicates no changes
to the tonal scale: The original input values exactly match the
output values. You may see a tone curve that isn’t straight when
you first view a photo that you haven’t adjusted. This initial curve
reflects default adjustments that Lightroom applied to your photo
during import.
The Darks and Lights sliders affect mainly
the middle region of the curve. The Highlight and Shadows sliders
affect mainly the ends of the tonal range.
- To make adjustments to the tone curve,
do any of the following:
Click on the curve and drag up or down.
As you drag, the affected region is highlighted and the related
slider moves. The original and new tonal values are displayed in
the upper-left of the tone curve.
Drag any of the four Region sliders left or right.
As you drag, the curve moves within the affected region (Highlights,
Lights, Darks, Shadows). The region is highlighted in the tone curve
graph. To edit curve regions, drag the split controls at the bottom
of the tone curve graph.
 Drag a split control slider to the right to expand that tonal
region; drag to the left to contract it. Click to select the Targeted Adjustment tool  in
the upper-left of the Tone Curve panel and then click on an area
in the photo that you want to adjust. Drag or press the Up and Down
Arrow keys to lighten or darken the values for all similar tones
in the photo.
Choose an option from the Point Curve menu: Linear,
Medium Contrast, or Strong Contrast. The setting is reflected in
the curve but not in the region sliders.
Note: The Point Curve
menu is blank for photos imported with metadata and previously edited
with the Adobe Camera Raw tone curve.

curve, choose an option from the Point Curve menu, click the Edit
