III Working with the Retouch and Spot & Patch Controls Aperture provides two sets of controls that you can use to retouch your image: Spot & Patch and Retouch. Which Retouching Tool Should You Use? In the vast majority of cases, Retouch provides the controls that will best serve your image-repair needs. The Spot & Patch controls have been included in Aperture 2 in order to retain the integrity of images that were adjusted with earlier versions of Aperture. In many cases, image repairs might even be improved by removing an existing Spot & Patch repair and replacing it with Repair or Clone repairs performed with the Retouch tool. For more information about the Retouch tool, see "Working with the Retouch Controls," next. There are certain situations in which Spot & Patch is the tool of choice. For example, an artifact on or very near a curved edge in an image may be more effectively removed using the Angle control. For more information about the Spot & Patch adjustment controls, see "Working with the Spot & Patch Controls" on page 386. Working with the Retouch Controls You use the Retouch tool and brushes to touch up imperfections in the image caused by sensor dust, image artifacts, and other environmental conditions. You can also copy an element of an image and paste it in another area for purely aesthetic reasons. Aperture provides two methods for retouching your images. The method you use depends on whether you are trying to copy texture from the source while preserving hard edges at the destination (where the blemish is) or simply copy pixels from one area of the image and replace them over another. If the area you need to repair has a hard edge near the problem area, you use the "repair" method. You also use the repair method when you want to copy high-frequency texture from one area of the image (the source) and brush the texture over the destination area while maintaining the underlying color and shading of the destination area. The second method, "cloning," is used when you simply want to copy pixels from one area and paste them on another area. Cloning is useful when you want to copy an element of an image as is, such as a bird, and paste it in another area. Chapter 15 Making Image Adjustments 381
