The Nave, Winchester Cathedral

This is a digital image, and the camera was tipped up 30 degrees. I

spent a very long time correcting the converging verticals, and the

result is still not perfect. Does anyone know of any software that

does a decent job emulating a slide lens or rising front? Photoshop

CS2 is crap - it does not understand perspective geometry. It would

have been much quicker to shoot it on a 5x4 camera.
