Pixels with luminance values less than the Black Input Level or greater than the White Input Level are made black. Everything between those points will appear gray or white. Note: The controls for this effect are similar to those of the Extract effect in Adobe After Effects, but the purpose and results of the effect are different. See also "Remove color in a clip" on page 274 Levels effect The Levels effect manipulates the brightness and contrast of a clip. It combines the functions of the Color Balance, Gamma Correction, Brightness & Contrast, and Invert effects. This effect functions much the same as the Levels effect in After Effects. The Levels Settings dialog box displays a histogram of the current frame (Windows only). See also "Adjust luminance using levels" on page 266 Lighting Effects effect The Lighting Effects effect applies lighting effects on a clip with up to five lights to introduce creative lighting. Lighting Effects lets you control lighting properties such as lighting type, direction, intensity, color, lighting center, and lighting spread. There is also a Bump Layer control to use textures or patterns from other footage to produce special lighting effects such as a 3D-like surface effect.
