Auto Color and Auto Contrast effects To the top The Auto Color effect adjusts the contrast and color of an image after analyzing the shadows, midtones, and highlights of the image. The Auto Contrast effect adjusts the overall contrast and mixture of colors. Each effect maps the lightest and darkest pixels in the image to white and black, and then redistributes the intermediate pixels. The result is that highlights appear lighter and shadows appear darker. Because Auto Contrast and Auto Color don't adjust channels individually, they don't introduce or remove color casts. The Auto Levels effect uses many of the same controls as the Auto Color and Auto Contrast effects. A quick way to remove (or at least reduce) the flicker caused by fluctuations in exposure and color from one frame to the next is to apply the Auto Color effect. This is useful, for example, in reducing the flicker of old film or for correcting for the flickering color of a light source. These effects work with 8-bpc and 16-bpc color. Temporal Smoothing The range of adjacent frames, in seconds, analyzed to determine the amount of correction needed for each frame, relative to its surrounding frames. If Temporal Smoothing is 0, each frame is analyzed independently, without regard for surrounding frames. Temporal Smoothing can result in smoother looking corrections over time. Scene Detect If selected, frames beyond a scene change are ignored when surrounding frames are analyzed for temporal smoothing. Black Clip, White Clip How much of the shadows and highlights are clipped to the new extreme shadow and highlight colors in the image.
