The Photoshop CS5 Book for Digital photographers part 35 is full-color, graphically rich, and contains project-based examples of every key step in the digital photography process. Integrating all the newest features of Photoshop CS5 into the book’s workflow, Scott shows readers how to work with their images like a pro, from importing to organization to correction to output. In addition to fully updating the book for CS5, Scott has also added a brand new chapter, which lets readers in on his entire, personal post-processing workflow by incorporating his popular 7-Point System into this book | The Adobe Photoshop CS5 Book for Digital Photographers Coming up with your own settings If you want to experiment and come up with your own custom blend of sharpening I ll give you some typical ranges for each adjustment so you can find your own sharpening sweet spot. Amount Typical ranges run anywhere from 50 to 150 . This isn t a hard-and-fast rule just a typical range for adjusting the Amount where going below 50 won t have enough effect and going above 150 might get you into sharpening trouble depending on how you set the Radius and Threshold .

If you really need to increase the intensity of your sharpening you can lower the Threshold to 0 but keep a good eye on what you re doing watch for noise appearing in your photo . The Final Image For the final sharpened image you see here I used the Portrait sharpening settings I gave earlier and then I just dragged the Amount slider to the right increasing the amount of sharpening until it looked right to me I wound up at around 85 so I didn t have to drag too far .
