CurvesUse Curves to adjust the tonal range of an image. You can adjust any point along a 0-255 scale while keeping up to 15 other values constant. The horizontal axis of the graph represents the original brightness values of the pixels (Input levels); the vertical axis represents the new brightness values (output levels). In the default diagonal line, all pixels have identical input and output values. To create a variety of interesting tonal and color effects, create or import curves and arbitrary maps from Adobe Photoshop. Curves supports all settings files created in the Photoshop Curves dialog box: either Curves files (.acv) or Arbitrary map files (.amp). The Curves effect does not support Adobe Photoshop color tables (.act). ![]() A. Shadows B. Midtones C. Highlights For more information, see the After Effects product section on Adobe's Web site. |
