Mastering Curves

Quick Fixes

Increase Brightness – Make a point near the middle of the line and move it up slightly to increase midtones.
Decrease Brightness – Make a point near the middle of the line and move it down slightly to decrease midtones.
Decrease Brightness And Contrast – Drag the pure white point (top right corner) down the side of the graph.
Made a Mistake? – While still in the curves window, hold Alt. The cancel button changes to reset, allowing you to restore original settings.

I hope this brief and simple guide to curves helps some of you out with your photography and digital art. If you would like further information or help understanding aspects of this topic, please post in the Tutorial Talk Forum.
