122 CHAPTER 6 Transforming and Retouching To adjust the perspective of a composition: 1 Select the Use Perspective option. 2 Select the vanishing point tool ( ), and click on an image in the work area to make it the vanishing point image. The vanishing point image is used to correct the perspective for the entire composition and has a light blue border when it is selected (as opposed to a red border). By default, the first image you drag into the work area is the vanishing point image. In an automatically assembled composition, the middle image is the default vanishing point image. There can only be one vanishing point image per composition. 3 If necessary, adjust the position of the nonvanishing point images. A non-vanishing point image has a red border when it is selected (as opposed to a blue border). When you apply perspective correction to a composition, the non-vanishing point images are linked to the vanishing point image. You can break this link by separating the images in the work area or by dragging the vanishing point image back to the lightbox. Once the link is broken, images return to their original shapes. The perspective correction only works up to approximately a 120° angle of view. For a wider angle of view, the Use Perspective option should be deselected. To change the perspective of a composition, select the vanishing point tool, and click on a non-vanishing point image in the work area. Notice how the perspective of the composition changes depending on which image is the vanishing point image. To rotate an image in the work area: 1 Select the select image tool ( ), and click on the image you want to rotate. 2 Select the rotate tool ( ). 3 Click near the edge of the image and drag in a circular motion around the center of the image. Hold down Shift to constrain the rotation to 45° increments. To clear a composition: Hold down Alt (Windows) or Option (Mac OS), and click New. All images in the work area are returned to the lightbox. Previewing a Photomerge composition The Cylindrical Mapping and Advanced Blending options are used to process the final image. The results of applying these options are visible only in Preview mode or in the final, generated image.
