Color Grade a Photo in Photoshop using Adjustment Curves?

Color grading with Curves is one of the most powerful techniques in Photoshop. It is the same method Hollywood colorists use to grade film.

While the master RGB curve changes brightness, switching to the individual Red, Green, and Blue channels allows you to inject specific colors directly into your highlights, midtones, and shadows.
