Contrast Boost

Figures 15.41 and 15.42 show a frame from shot 6, both before and after contrast enhancement. In nontechnical terms, a contrast boost involves making the darks a bit darker, the lights a bit lighter, and leaving the middle alone. To translate this into RGB Curves, the top end of the curve, which represents the highlight area, needs to go up (lighter), and the low end of the curve, which represents the shadows, needs to go down (darker). The curve that made the adjustment between the two previous illustrations is shown in Figure 15.43. This is commonly referred to as an “S” curve, or a standard contrast curve.
