But the question isn't that (which can be settled with a level, or in some modern cameras a built-in sensor). The question is, does the picture "look right?" If the actual landscape has a long flat tilted bit, it may very well look better to have the "real" but invisible horizon tilted, with the visible horizon straight. > If the tree would be canted, then perhaps it constitutes the right angle > of the horizon.

Which is in turn subjective of course. -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
