Tone Cur ve
The Tone Curve lets you perform color and tonal corrections by adjusting either individual
color channels or the composite (RGB) channel.
The x-axis of the graph represents the original tonal values (from highlights on the right, to
shadows on the left); the y-axis of the graph represents the adjusted tonal values (from dark/
less color at the bottom, to light/more color at the top).
The diagonal line on the graph is what you adjust to create your “curve”. Moving the curve
up and to the left lightens the clip and increases the color in any channel; moving the curve
down and to the right darkens the clip or decreases the color of a given channel. If you have
a clip with a blue cast, for example, you can decrease the blue in the image by selecting the
Blue channel and moving the curve down and to the right.
You can add one or more nodes to the curve, to give you more precise control over the areas
that you want to adjust.
