curve can be used in the future if necessary.

The Load button lets you load a previously saved tone curve for use with
another image. Photoshop-saved curves can also be loaded.

Input shows the horizontal value of wherever the cursor is inside the curve,
reflecting the scanner' s full depth.
Output shows the vertical value of wherever the cursor is inside the curve,
reflecting the scanner' s full depth.
Zoom indicates the magnification level of the curve box. At 100% zoom, the
curve is seen in its entirety. Using the zoom frame tool to magnify the curve
will zoom in or enlarge your view of the curve, resulting in a higher zoom
percentage.
Use the Curve Pointer tool to define points in the curve that will be
modified. When you click on any point in the curve, a black handle
appears to mark your position. To remove the handle, drag it off
the graph.
Use the Curve Zoom Frame tool to zoom in and out on a particular
point in the curve. Once the area is zoomed in, you can then use
the Curve Pointer tool to define new points for better precision.
This is particularly useful for working with 12-bit images, where
more detail can be seen in such images. The zoom level can be seen
in the Zoom field. To zoom out, click Shift.
Use the Curve Pane tool to scroll through the curve if the curve
has been zoomed in. This curve tool can be used only if the curve
has been zoomed in with the Curve Zoom Frame button (above).
Otherwise, the Curve Pane tool will be dimmed.
