If your original is too dark or too light, you lose vital detail
after scanning. You can fix this problem by using curves.
The curve function is applicable to grayscale and 24/48-bit
color images. Simply put, if you knew how to use Adobe®
Photoshop® or any other equivalent softwares’ curve
function, you can safely skip this section.

Applying a curve to an image is to enhance favored
brightness ranges at cost of others, like enhancing the
shadow at cost of the highlight and midtone. If done

properly, you can energize a dull image using curves without
sacrificing the overall image quality. To write a curve, simply
place an anchor on the diagonal line and adjust its position.
Add more anchors if you have to write a more complex curve.
You can also remove anchors.

To emphasize shadow, raise the anchor; to emphasize
highlight, lower the anchor; to emphasize midtone, write an
S-shaped curve; to decrease contrast, write an inverted S-
curve.
Experts apply curves to individual channels to color-correct
an image. Usually this is done to a CMYK image to be
printed.
