Photoshop CS4 Studio Techniques- P7: Staring at a shelf full of Photoshop books at the localbookstore, it seems that there are more special-effect“cookbooks” and technical tomes than anyone would evercare to read. The problem is that none of those “cookbooks”provide enough detail to really let you feel like youunderstand the program

Photoshop CS4 Studio Techniques- P7Chapter 4 Using Camera Raw 5.0 areas are starting to have less detail (colored areas), and which areas haven’t lost any detail (they’ll look white). The Shadows clipping button above the left side of the histogram makes areas that are losing detail appear in blue in Camera Raw. Unlike the Highlights clipping button at right above the histogram, the Shadows clipping button only indicates where an area has become solid black. It doesn’t indicate areas that are losing detail in just one or two of the colors that make up the image. You may still prefer to use the Option/Alt method because you’ll often want to know where you’re losing detail in just one or two colors in the image. Hold down Option/Alt and move the Blacks slider until you see the first hints of pure black showing up; then back off just slightly so you don’t trash the detail anywhere (Figure 4.27). Figure 4.27 Hold down the Option/Alt key and move the Blacks slider to see where the pure black is within the image. If you decide not to use the Shadows clipping warning feature when moving the Blacks slider, be sure to keep an eye on the histogram. If you see a spike on the left side, you’re losing shadow detail. If the spike is white instead of a color, you’re starting to get some solid black areas in the image. One quick way to make images really “pop” is to bring up the Blacks slider just to the point where the image is looking too dark and then bring the exposure up slightly to compensate, being careful not to overexpose the image. Figures 4.28 and 4.29 show an image loaded and then adjusted with Blacks and Exposure. You can use the Recovery slider to pull in detail to highlight areas.166 II: Production EssentialsFigure 4.28 An original raw image loaded into Camera Raw.

Move the slider to the left if the image needsto be darker (Figures 4.30 and 4.31), or move it to theright to brighten the image (Figure 4.32). If you’re plan-ning to make radical changes in brightness, use Curves(see Chapter 3) after you’ve opened the image in Photo-shop. You’ll have a lot more control over the process withCurves, but it won’t hurt if you make a slight tweak usingthe Brightness slider.Figure 4.30 An original image with Figure 4.31 The image from Figure Figure 4.32 The image from Figurethe brightness set to a default of 50. 4.30 with the Brightness slider set all 4.30 with the Brightness slider all the(©2008 Dan Ablan.) the way to the left. way to the right. 167Chapter 4 Using Camera Raw 5.0 Contrast Slider Most of the time, you should adjust the contrast of your ...
