Chapter 16. Retouching > Cloning in Perspective

Cloning in Perspective

Before Vanishing Point came along, Photoshop's Clone stamp tool could not recognize distortions caused by perspective (Figure 16.64). Consequently, it created unacceptable results when used on an image that contained noticeable perspective (Figure 16.65). The main problem is that the Clone Stamp tool is not capable of scaling the cloned area to make it match the perspective of the surface you are attempting to retouch. In the example shown here, the area being covered by the sign is primarily a row of larger bricks. If you look closely at the results obtained in Photoshop, you might notice that the row of large bricks ends up being patched with bricks that are much too small to look appropriate. The Clone Stamp tool in Vanishing Point, however, can do a much better job. To start, you would use the Create Plane tool and click on the two corners that make up the left edge of a brick and then click on the two corners that make up the right edge of another brick in the same row so that Photoshop is aware of how the bricks are distorted by perspective (Figure 16.66). Then, you would drag the size handles of the resulting grid to define the overall area that needs to be retouched (Figure 16.67). Once the plane has been defined, the Clone Stamp tool can be used to retouch areas and its results will be scaled to conform to the perspective of the image (Figures 16.68 and 16.69).
