Highlights	Lightest portion of the image
Mid-tones	Part of the image between dark and light tones
Shadows	Darkest portion of the image

As you drag the handles of the curve, you will see the values in the associated fields change.

You can also type the numbers by clicking in the field you wish to modify.

Acceptable values range from 0 (maximum darkness) to 100 (maximum lightness) for each handle.

❍To locate a color range in the tone curve, move the pointer over the specific area of your image and click while holding down the Option key.

A line will appear on the tone curve corresponding to the area under the pointer. In this way you can tell exactly where to make your adjustments.

Changes made to the Master (gray) Tone Curve will automatically modify the red, green, and blue channels.

Tone curves can be used to shift the overall color, brightness, and contrast of a given scan in any direction.
