Perspective Correction

Top  Previous  Next


A typical case of perspective distortion involves architectural photos. The example below shows a church, with narrowing towers towards the top of the image. If you move the top left & right red handles outwards, you can correct this distortion. You will, however, loose portions of the image (2). If you want to decide yourself, which parts of the image should remain visible (clipping), you can either pan the image behind the red handles, or start by extending the workspace (3), in order to position a separate crop frame (4) after the correction.
