A screen-capture movie of the use of Hugin to correct perspective-induced distortion in a photograph. This uses the original version of File:Merrill Wisconsin City Hall Historic.jpg, but this is not a recording of the actual correction applied to that image and uploaded to Commons. Final results are displayed in the GIMP image manipulation program. This is a recording of a quick session to demonstrate the techniques used, though without the usual care given to ensure the best possible outcome. This was recorded on a Linŭ system running Kubuntu 12.04.2. Hugin and GIMP are available for other platforms.
