I am trying to correct the perspective in an image using the Perspective Correction filter in PS2. All I want to do is widen the top of the image to make all the vertical lines perpendicular to each other. I want to keep all the elements in the image at their exact same locations vertically but to simply get wider towards the top of the image. However, when I apply the perspective correction in PS it distorts the image elements by shifting them downward increasingly as the image gets narrower, in the case of my image, so that the upper elements are longer and the lower elements are narrower or more squashed. I do not want this to happen but I don't know how to pevent it in PS. I don't want to crop any of the top or bttom of the image either. I simply want to widen the top of the image while keeping all of the elements in their same locations vertically. Does this make sense? And can this be done simply in PS? This should be an easy task in PS but I just can't figure out how to do it in this program. If what I am asking for is not clear I will try to post examples but I have not done that before and I would rather not take the time to learn that right now.
Thanks,
Tim
