So much has changed in Adobe Photoshop Elements 3 that it is practically a whole new program, and Mikkel Aaland has completed quite an amazing undertaking with Photoshop Elements 3 Solutions. | Applying Perspective Control Look at the Settings box in the Photomerge work area shown in Figure . You ll see that Normal is selected and Perspective is not. Normal is the default setting which works fine for most landscape and scenic shots. However at times applying a perspective improves a panoramic and makes it look more natural. Often you won t know unless you try. To apply a perspective to my panoramic I selected Perspective from the Settings box Figure shows the results. The perspective didn t look right to me but I can try to fix it by setting a different vanishing point. By default if Perspective is selected Photomerge makes the middle image the vanishing point and outlines it in a light blue border when it is selected. 194 Figure Here is the image after applying Perspective control. The vanishing point by default is set to the middle image outlined in blue. CHAPTER 8 CREATING PANORAMICS WITH PHOTOMERGE What is a vanishing point It s helpful to think of the vanishing point image as a base image or one that sets the perspective for all the others. For example if the vanishing point image is in the middle as it is in this example the images on either side are transformed so that they lead the eye toward the center. If you look again at Figure you ll see the bow-tie configuration that I found objectionable. To try another vanishing point I simply selected the Set Vanishing Point tool K and clicked another image in the work area. In Figure I made the image on the left the vanishing point. See what happens to the perspective In an attempt to correct the perspective to the new point of view the images to the right of the vanishing point are transformed in size and shape. To deselect the vanishing point completely and start over I simply clicked the Normal radio button. Undo works for this as well. Figure This is the result after I applied Perspective control and set the vanishing point to the image on the far left outlined in blue. 195 .
