Often overlooked and rarely exploited to the fullest, Hue/ Saturation is a very powerful tool. Using the three sliders together, you can adjust the hue to eliminate a color cast, increase saturation so that your colors appear richer and more vibrant, and adjust lightness to improve your image's tonality. (See Figure 6-10.) Keep in mind that when you adjust something that's very dark, start with the Lightness slider so that you can evaluate the other changes (Hue and Saturation) properly. Remember, too, that you can apply Hue/Saturation (like a number of other adjustments) to a specific range of colors in the image, selected in the pop-up menu at the top of the dialog box.

Figure 6-10: Hue/Saturation cures three problems at once.

If you need to simulate a duotone image (a picture created by using just two inks), apply a Hue/Saturation adjustment layer, mark the Colorize check box, adjust the sliders, save, and then print. If the inkjet printer introduces a color cast that changes the appearance of the image, reopen the adjustment layer and make the change necessary to compensate for the color cast.
