I've been growing frustrated by wide angle lenses - not so much their distortion, but by their POV with looming foregrounds, tiny distant backgrounds, etc. I've owned a Noblex, which is better but not a complete answer. What I think I really like best is stitching several 4x5s shot with "normal" lenses. So far I've only used Photoshop, working carefully, and avoiding difficult subjects like overlapping brick walls. But has anyone found anything better than doing it by "hand"? Especially a Mac OSX solution?
