Has any of you with the fancy dancy digital SLRs tried any shift or perspective control lenses? They make for some interesting photo-gymnastics. I'm sure you could find them for rent somewhere.
Extreme rises or shifts allow for strange viewpoints whilst keeping vertical lines as Nature intended.
I've got a bit of advantage with some of my lenses. My 210mm has a 300mm image circle so I can employ tremendous shifts.
Just another piece of pasta in the big alphabet soup of a.net.
