Photoshop 6 for Windows Bible- P28:If you are reading this foreword, it probably means that you’ve purchased a copy of Adobe Photoshop , and for that I and the rest of the Photoshop team at Adobe thank you. If you own a previous edition of the Photoshop Bible, you probably know what to expect. If not, then get ready for an interesting trip. | Chapter 17 Mapping and Adjusting Colors 783 Consider the digital photograph featured in Color Plate 17-12. Snapped several years back in Boston s Copley Square using a Kodak DC50 digital camera the original image at the top of the color plate is drab and lifeless. If I used the Hue Saturation command to pump up the saturation levels a world of ugly detail rises out of the muck as shown in the second example. Obviously I ve taken the saturation a little too high but only to demonstrate a point. The detail would have faired no better if I had used the Variations command to boost the saturation. Unstable colors may be the result of JPEG compression as in the case of the digital photo. Or you may have bad scanning or poor lighting to thank. In any case you can correct the problem using our friends the Median and Gaussian Blur commands as I explain in the following steps. If you find yourself working with heavily compressed images on a regular basis you may want to record these steps with the Actions palette as explained in Chapter B on the CD-ROM at the back of this book. Unlike the Adjusting the Focus of Digital Photos steps back in Chapter 10 you won t want to apply these steps to every digital photograph you take or even most of them but they come in handy more often than you might think. STEPS Boosting the Saturation of Digital Photos 1. Select the entire image and copy it to a new layer. It seems like half of all Photoshop techniques begin with Ctrl A and Ctrl J. 2. Press Ctrl U to display the Hue Saturation dialog box. Then raise the Saturation value to whatever setting you desire. Don t worry if your image starts to fall apart that s the whole point of these steps. Pay attention to the color and don t worry about the rest. In the second example in Color Plate 17-12 I raised the Saturation to 80. 3. Choose Filter Noise Median. As you may recall from the last module Median is the preeminent JPEG image fixer. A Radius value of 4 or 5 pixels works well for most .
