TAILIEUCHUNG - Photoshop cs5 cho nhiếp ảnh gia part 17

Sử dụng Công cụ diệt Spot Các công cụ gỡ bỏ tại chỗ tương tự như công cụ Clone và chữa bệnh brush trong Photoshop, mặc dù không phải là khá mạnh mẽ. Các công cụ gỡ bỏ tại chỗ đặc biệt thích hợp để loại bỏ bụi mà bệnh dịch nhiếp ảnh kỹ thuật số nhiều nhất. Thật không may, kể từ khi chỉnh sửa trong ACR được giới hạn các điểm tròn, nó không phải là rất thích hợp cho loại bỏ đối tượng. | __a 97 Figure The Straighten tool automatically crops and straightens your image. USING THE ACR INTERFACE Using the Spot Removal Tool 1. 2. The Spot Removal tool is similar to the Clone and Healing Brush tools in Photoshop although not quite as powerful. The Spot Removal tool is particularly well suited to removing the dust that plagues most digital photographers. Unfortunately since retouching in ACR is limited to circular spots it is not well suited for object removal. That type of retouching is best done later in Photoshop. If you are using a Smart Object-based flexible workflow see Chapter 5 it s helpful to do as much of your dust removal as possible in ACR. That way anytime you change the Smart Object your retouching will automatically change as well. If you use the flexible workflow but do your cleanup in Photoshop some changes you may make later to the Smart Object your background layer with the raw file may force you to have to redo the cleanup layer. For instance if you make tonal or color corrections to the raw file any cloning and healing that was based on the previous settings will no longer match. To use the Spot Removal tool follow these steps Zoom into your image to 100 magnification. Begin at one corner and systematically work your way through the image. Photoshop ONLY 3. When you find a speck of dust click the Spot Removal tool. As shown in Fig- 98 ure several new options appear to the right of the image. Figure After clicking the Spot Removal tool specify the Heal or Clone tool as well as the radius opacity and whether to show an overlay of the corrections. CHAPTER 3 ADOBE CAMERA RAW 4. Select either Heal or Clone in the Type drop-down menu. Clone will copy the pixels from another area that you choose to replace the dust whereas Heal will copy the texture and blend the color just as the similar tools do in Photoshop. For more in-depth coverage of cloning and healing see Chapter 5. 5. Check Show Overlay so a circle will remain showing .
