PHOTOSHOP CS3 98 User Guide Clarity, Saturation, and Vibrance controls in Camera Raw You can change the color saturation (vividness or color purity) of all colors by adjusting the Clarity, Vibrance, and Saturation controls on the Basic tab. (To adjust saturation for a specific range of colors, use the controls on the HSL / Grayscale tab.) Clarity Adds depth to an image by increasing local contrast. This setting is similar to a large-radius unsharp mask. When using this setting, it is best to zoom in to 100% or greater. To maximize the effect, increase the setting until you see halos near the edge details of the image and then reduce the setting slightly. Vibrance Adjusts the saturation so that clipping is minimized as colors approach full saturation, changing the saturation of all lower-saturated colors with less effect on the higher-saturated colors. Vibrance also prevents skin tones from becoming oversaturated. Saturation Adjusts the saturation of all image colors equally from -100 (monochrome) to +100 (double the saturation). HSL / Grayscale controls in Camera Raw You can use the controls in the HSL / Grayscale tab to adjust individual color ranges. For example, if a red object looks too vivid and distracting, you can decrease the Reds values in the nested Saturation tab. The following nested tabs contain controls for adjusting a color component for a specific color range: Hue Changes the color. For example, you can change a blue sky (and all other blue objects) from cyan to purple. Saturation Changes the color vividness or purity of the color. For instance, you can change a blue sky from gray to highly saturated blue. Luminance Changes the brightness of the color range. If you select Convert To Grayscale, you see only one nested tab: Grayscale Mix Use controls in this tab to specify the contribution of each color range to the grayscale version of the image. Tone a grayscale image in Camera Raw Use the controls in the Split Toning tab to color a grayscale image. You can add one color throughout the tonal range, such as a sepia appearance, or create a split tone result, in which a different color is applied to the shadows and the highlights. The extreme shadows and highlights remain black and white. You can also apply special treatments, such as a cross-processed look, to a color image. 1 Select a grayscale image. (This can be an image that you converted to grayscale by selecting Convert To Grayscale in the HSL / Grayscale tab.) 2 In the Split Toning tab, adjust the Hue and Saturation properties for the highlights and shadows. Hue sets the color of the tone; Saturation sets the magnitude of the result. 3 Adjust the Balance control to balance the influence between the Highlight and Shadow controls. Positive values increase the influence of the Shadow controls; negative values increase the influence of the Highlight controls. Adjust color rendering for your camera in Camera Raw For each camera model it supports, Camera Raw uses profiles to process raw images. The profiles are produced by photographing a color target under different white-balanced lighting conditions. When you set white balance, Camera Raw uses the profiles for your camera to extrapolate color information.
