The Chroma Editor The chroma editor is a useful tool for adjusting color saturation. Steepening the curve increases saturation in the affected range, making colors more vivid. Flattening the curve results in flatter, less vivid colors. Moving the gray point to the left makes the image as a whole more vivid, while moving it to the right "averages out" the differences between colors in the image, making the image grayer overall. In general, the most effective use can be made of the scanner's dynamic range by steepening the curve in the portions of the histogram that contain the greatest number of pixels while leaving colors corresponding to a neutral gray unaffected. The chroma editor is shown below. Output level sliders Black point slider Input/output levels Histogram White point slider Gray point slider Item Description Histogram Shows the distribution of pixels of different chromas in the input image.
