This is the ceiling of the organ room at the Longwood conservatory.
Yes, the straight lines do betray some lens distortion (the ceiling is
flat), but then this is just my "cheap" $400 consumer-grade 28-135mm
lens. I've been debating whether to spring for the 24-105mm "L" lens
to replace this. Of course, I'd be really PO'ed if I got this same
effect after spending THAT kind of money.
