CHROMA Chroma Curve Chroma Output Slider Set Anchor Point Reset Current Channel Reset All Channels Temporary Cancel Button Anchor points can be removed by simply clicking and dragging the anchor point off the Hue Map. Use the Width slider to increase or decrease the range of similar colors affected by the color identified with the anchor point. The Output slider affects the saturation of all of the colors throughout the image evenly. Moving this slider up will increase the saturation of all colors, while moving this slider down will decrease the saturation of all colors. The Chroma Editor contains a number of additional controls: Adjust Menu The Chroma Editor enables you to edit the Chroma, or saturation, of the entire image or of specific colors within the active image without affecting Luminosity or Hue. Within the Chroma Editor, you are provided with a Hue Map, representing the full spectrum of colors on the horizontal axis, with the Chroma of the colors of the vertical axis. Superimposed above this Hue Map, you are provided with a Chroma Curve that can be used to isolate and adjust the Chroma of individual colors. Clicking on the curve will create an anchor point. Moving that anchor point upward makes colors in the affected portion of the color range more saturated. Taking that same anchor point and moving it downward makes the affected colors less saturated. Exclude Gray Check this box to prevent any saturation increases from affecting neutral colors (grays) in the image. This is helpful as neutral colors (grays) may seem oversaturated when chroma is raised. Please note: The Exclude Gray option has no effect when chroma is lowered below the value in the original image. Set Anchor Point Click on this button and then click on the active image to select a color to place an anchor point on the Chroma Curve. Reset Current Channel Click on this button to reset only the Chroma Editor to the default values.
