|Tone curve||SWPP Photographic Glossary|
Tuesday 13th October 2015
A graph used in digital photography that displays tonal range. A straight line at 45 degrees shows that the contrast is unchanged. To modify contrast you can usually click anywhere on the line and pull it in any direction. You can usually also select one of the colour channels and modify contrast on just that channel which will affect the colour balance.
