Understanding the Edge Sharpen Workflow The Edge Sharpen adjustment in Aperture is a professional tool that's used to sharpen photos. Using the Edge Sharpen adjustment controls in conjunction with the following workflow makes it easy to achieve professional results. To sharpen an image: 1 In the Edge Sharpen area of the Adjustments inspector or the Adjustments pane of the Inspector HUD, set the Intensity slider to the maximum value to see the effect of the operation. 2 Adjust the Edges slider so you can see which parts of the image are being sharpened. If possible, adjust the Edges slider so that edges are sharpened, but noise and texture in the image are not affected. 3 Adjust the Falloff slider so that the edge sizes you want sharpened the most are accentuated. 4 Decrease the Intensity parameter value until the sharpening effect is appropriately subtle. Values below 0.5 usually work best. Working with the Sharpen Controls You use the Sharpen adjustment controls when you need to modify Sharpen adjustment control parameters that were applied to an image in a previous version of Aperture. To sharpen an image using the Sharpen controls: 1 Select an image. 2 If the Sharpen controls are not shown in the Adjustments inspector or the Adjustments pane of the Inspector HUD, choose Sharpen from the Add Adjustments pop-up menu. 3 Sharpen the image by doing one of the following: Use the Intensity slider and value slider to adjust the strength of the sharpening adjustment. Use the Radius slider and value slider to adjust the area over which the sharpening adjustment is applied. Â By default, the Intensity slider is set to 0.50. Drag the Intensity slider to the right to increase the intensity of the sharpening effect on the image, and drag the Intensity slider back to the left to reduce it. 462 Part III Performing Image Adjustments
