Enhancing Images

Editing Curves Directly

Fine adjustments can be made to brightness and contrast in speciﬁ c portions of the tone range

by adding additional points to the curves for each channel. These points can be freely ad-

just ed by drag ging them into new positions, changing the shape of the curve. Steepening the

slope in a given portion of the curve will enhance contrast in that portion of the tone range.

Changing the curve so that input levels in a given portion of the tone range are mapped to

higher output levels will brighten tones in the affected tone range; similarly, chang ing the

curve to map input levels to lower output levels will darken tones in the affected range.

Adding New Points to the Curve

Move the cursor over the curve edit display and click once to enter curve edit mode. Move

the cursor to the position where you would like to add a new point, then click. A new point

will be added at this position and the curve will automatically be adjusted to pass through this

point. A point corresponding to a selected location in the active image can be added by click-

ing the

button and then clicking in the desired area in the image window. The position of

the point can be adjusted by dragging it to a new location within the curve edit display. The

image in the active window will automatically be adjusted to reﬂ ect changes to the curve.

Removing Points from the Curve

Points can be removed from the curve by dragging them out of the curve window.

Resetting the Active Curve to Linear

The default linear curve for the current channel can be restored by clicking the button in

the Curves palette.

Resetting All Curves to Linear

To reset all curves to linear, click the button. All curves will be reset and the RGB master

channel will be displayed in the Curve palette.
