When the curve is moved up or down, the relationship between input value and

output value changes accordingly.

• In areas where the curve is moved down, pixels in that portion of the image

are darkened.

• In areas where the curve is moved up, pixels in that portion of the image are

lightened.

Contrast in an image can be seen by the angle of the line. The steeper the slope,

the higher the contrast. The closer the line is to horizontal, the lower the

contrast.
