3. Position your cursor over the handle. The cursor becomes a crosshair,
indicating that you can drag the curve handle. Drag the handle and
release. The curve remains where you moved it, and the image in the
preview area reflects the change in tone. You can specify up to 15 anchor
points, including the end points.
4. Because the curve reflects mathematical calculations related to the image
tones, it does not move exactly where you want. You can move the curve
in the following ways:
• Drag a curve handle up or down.
• Click on another part of the curve to set a new handle. You can have
as many handles as you want. However, it is best to experiment and set
your handles at points in the curve where you want to bend it.
• To remove a handle, drag it off the curve, or right-click the handle.
5. Click Reset to undo a change to the curve.
6. Click Save to save your custom curve.
7. Specify a file name and click OK.
The curve is saved in the location you specify.
