Color Correction - Tone Curve Settings

Precise changes to the tone settings of an image can be made by directly editing the tone curve. This enables you to make subtle changes to the brightness of only the shadows or highlights, if desired.

The method is applicable to 8-bit grayscale, 12-bit grayscale, 24-bit color (when ColorSync™ is off) and 36-bit color images.

The Tone Curve

In the Plug-in module FS Tone Curve chart, the input is the image received by Plug-in module FS and the output is the image displayed on the screen. The Tone Curve shows the balance between light

and darkness in the input and output.

Color Correction with the Tone Curve

The image can be adjusted by changing the shape of the tone curve.

If the mid-range tones of the tone curve are moved down toward the input side its image will become darker than the shadow of the output side and the displayed image will become darker.

*For the most natural appearance the tone curve should be as smooth as possible. The changes you make in the tone curve are immediately reflected in the preview area so you can try many different settings until you achieve the image you want.
