III 5 For maximum accuracy, the Edge Sharpen adjustment sharpens the image in three passes that appear to occur simultaneously-an initial sharpening pass, where a majority of the sharpening occurs, followed by two subsequent sharpening passes. These subsequent passes are called falloff. Adjust the amount of sharpening applied in the subsequent sharpening passes by doing one of the following: Use the Falloff slider and value slider to adjust the strength of the subsequent sharpening passes. Â Drag the Falloff slider to the right to increase the percentage of the original sharpening that's applied during the subsequent sharpening passes, and drag the slider back to the left to reduce it. Â Click the left or right arrow in the Falloff value slider to adjust the falloff percentage by 2 percent increments, or drag in the value field. Â Double-click the number in the Falloff value slider, then enter a value from 0.00 to 1.00 and press Return. The falloff percentage is applied proportionally to the second and third sharpening passes. For example, if 0.69 (69 percent) is set as the Falloff parameter value, 69 percent of the original amount of sharpening is applied during the second sharpening pass, and 69 percent of the amount of sharpening from the second sharpening pass is applied during the third sharpening pass. In other words, only 47.6 percent of the amount of the original sharpening is applied during the third sharpening pass. Chapter 15 Making Image Adjustments 461
