The Adjust Colors effect lets you control the hue, saturation, and value of an image in much the same way as you would adjust your television. It also lets you adjust the image colors equally or by using the luminosity of an external source.
When using luminosity to adjust colors, pixels with higher luminance undergo greater color adjustments.
You can choose any of the following adjustment methods:
| • |
Paper — uses the selected paper grain to control the color adjustment |
| • |
Image Luminance — uses the luminance of the image as the model for color adjustment. Areas of greater luminance are adjusted more. |
| • |
Original Luminance — uses the luminance of the clone source as the model for color adjustment. If you have not set up a clone source, the current pattern is used. |
| • |
[Alpha channel] or [Layer mask] — sets the selected alpha channel or layer mask as the model for controlling color adjustment. For example, a black-to-white gradation in the channel or mask lets you adjust the color progressively across the image. In black areas of the channel or mask, colors are not changed. In white areas of the channel or mask, the adjustment applies fully. Transitional areas receive proportional color adjustments. |
Use the Adjust Color dialog box to change the hue, saturation, and value of an image.
