Perspective

When photographing buildings I try to hold the camera straight to avoid the ugly effect of converging verticals. Unfortunately, this isn't always possible: Either I can't go back far enough or I can't climb high enough to see the entire building without tilting the camera. Photoshop's Perspective option of the Crop tool can fix converging verticals. Below are my first attempts.
