    The [Tone Curve Adjustment] screen is displayed.

    Make the adjustment while checking the sample images under [Before Adjustment] and [After Adjustment].

    • To change the displayed part of the image, move the scroll bar.

    • You can use the buttons under the sample images to turn the images 90 degrees clockwise and counter-clockwise, and to zoom in and out the images.

    • To make an image brighter (to make colors lighter), make the curve more concave.

    • To make an image darker (to make colors deeper), make the curve more convex.

    • To raise the contrast (to make darker colors darker and lighter colors lighter for enhanced sharpness), make an S-shaped curve.

    • To lower the contrast (to make darker colors lighter and lighter colors darker for more even expression), make a reverse S-shaped curve.

  8. After making the adjustment, click [Save].

  9. Enter the name of the adjusted tone curve. Select [Controller] as the [Destination Folder] and click [Save].

    Selecting [Controller] saves the spot color to the image controller.
