Rick Waller Posted July 6, 2006 Share Posted July 6, 2006 Need a little help here please. Took an image of a building for my son to use in a brochure. Because of the cramped positioning, I was unable to shoot with a level camera and the image tilts back and inward. I tried crop fix and other perspective fixes in PS, but was unable to "straighten" the vertical lines on the outer edges of the building. Any special tricks to rectify this severe keystoning? Anyone good with the Free Transform tool? Link to comment Share on other sites More sharing options...
vivek iyer Posted July 6, 2006 Share Posted July 6, 2006 Eric, Upgrade your PS to PS9 (PS-CS2, Check adobe's site, about $170). Link to comment Share on other sites More sharing options...

brooks short Posted July 6, 2006 Share Posted July 6, 2006 Eric, Here's a technique which works with older Photoshops such as PS 5. Open your image and zoom out one step so there is some extra canvas around the image. Using the rectangular marquee, select the entire image. Click Edit-Transform-Distort Notice the small handles in the corners and middle of the sides of the image. Pull the left corner up and out, then the right corner up and out to the shape you desire. You can adjust and readjust the image to suit then click enter to do the transformation. You can use the handles in the middle of the edges of the image to stretch left, right, up or down also.

Ed_Ingold Posted July 6, 2006 Share Posted July 6, 2006 You can use the free-transform tool, especially while holding the "shift" key, but there may be an easier way. First rotate the picture so that the center line is perfectly vertical. Then "select all" and use the perspective transform symmetrically - stretch the top and squeeze the bottom equally. That way you preserve the aspect ratio of the original subject. Finally, crop away the chunks that "squeezing" removes. The key is to normalize the centerline.

Ed_Ingold Posted July 6, 2006 Share Posted July 6, 2006 One other thing...it helps to create ruler lines to line up the verticals. Link to comment Share on other sites More sharing options...
brooks short Posted July 6, 2006 Share Posted July 6, 2006 The easiest way to rotate the image so that it is level is to zoom into an area near the center of the image which has a straight line or edge that is supposed to be level. It can be a horizontal or vertical edge near the center of the image. Using the measuring tool, trace a segment of that edge or line. Click image-rotate canvas- arbitrary and the image will autimatically rotate the correct number of degrees to place that line level either horizontally or vertically. No need to use a grid or guess the number of degrees needed. Link to comment Share on other sites More sharing options...
Rick Waller Posted July 7, 2006 Author Share Posted July 7, 2006 Thank you all. You guys are great. Seems to have done the trick. Still playing aroung with fine tuning the image, but I have the concept down pat now. Again - many thanks. Link to comment Share on other sites More sharing options...
