Photoshop CS5 Trickery & FX: Simplifying The Interface - Part 3
Other Features In ACR 5
Next, let’s look at the Curves feature. Click the Tone Curve tab to access the standard Curves command to control the contrast in the scene. You have two options. The Point option (see Figure 1.80) basically gives you the standard Curves dialog box. Notice that it has a slightly different look and that the histogram is included in the background to help you assess visually where the tones are on the graph.
The second option, Parametric, not only gives you the standard Curves, but it also gives you the sliders for adjusting the shadows, midtones, and highlight information (see Figure 1.81). You adjust these sliders just as you do in Levels.
Now, take a look at the Hue (A), Saturation (B), and Luminance (C) options in Figure 1.82. Each has its own set of sliders to apply changes to primary and secondary colors. Dividing up all these colors for each aspect gives you incredible control over the color balance, white balance, and the overall color scheme.
The Hue gives you access to both the primary and secondary colors in your image. If your intention is to isolate a particular color in your photograph and alter that color, then you would choose the designated slider and make your changes to that color only. For example, if you would like to have green leaves take on a warmer appearance, then you would select the slider for the Green Hues and pull that slider to the left toward a yellowish, green look.
The Saturation option increases or decreases the saturation of each individual color that is present in your image. Finally, the Luminance option selects a certain color that is present in the photograph and alters that color toward white or black.
Let’s take a look at a few other nice features in the new ACR. For instance, the Detail feature applies an unsharp mask to sharpen your imagery (see Figure 1.83).
Next, Split Toning allows you to create images that are dominated by two colors (see Figure 1.84). Traditionally, this was a common technique created by using two types of toner baths to add color to black-and-white prints.
Finally, options are available for chromatic aberrations (Figure 1.85A) and color corrections for your camera profile (Figure 1.85B), as shown in Figure 1.85. You can also apply any presets (Figure 1.85C) that were created in ACR.
