Before (left) and after (right) applying the Brightness/Contrast effect.
When using the curve, you can adjust the contrast or brightness of colors while maintaining the tonal
transitions in the original image. You can adjust all colors at once, or adjust R, G, and B individually. As
you adjust the Contrast or Brightness sliders, the endpoints of the curves remain fixed. Because the effect
maintains the levels from the original image, there are always 256 distinct levels, regardless of how much
you adjust the sliders.
Contrast adjusts the difference between light and dark values. As you increase the contrast, the curve takes
on an “S” shape, indicating that light colors are becoming lighter and dark colors darker. If you decrease
the contrast, the curve takes on an inverted “S” shape and tones down the contrast of all midtone colors.
