Sorry Mark but your correction of my picture of the Basilica of Mary Magdalene introduce a totaly wrong perspective. The main problem is not the film plane being perpendicular to the ground it's to be at right height when shooting. However if someone can give me a full tilt & shift view camera with a Schneider Super-Angulon and drum scanner I think I could get some fully perspective corrected view... I've tried software correction on some pics, even properly applied they just look false to me you have more shapness ot one end of the picture that the other and you never get rid of the barrel distortion of wide angle lenses.

 * It's quite possible that I got it all wrong: after all, I wasn't on location and was working purely from the image, so I don't really understand in what sense the perspective is wrong. All I tried to do is make the vertical lines appear vertical (and reduce the contrast a bit).  I agree that this would be easier with a tilt/shift lens or a large format camera, but software correction of perspective is the next best thing when such options aren't available.  If you had to tilt the whole camera upwards, then software perspective correction will undo that movement for you.  The only way to get the whole image sharp is to use a small aperture, or perhaps judicious cropping. --MarkSweep 23:19, 11 Jan 2005 (UTC)
