Architecture
Keystoning
With architecture you got to get those lines straight and parallel with the edges of the frame. In digital, it's as easy as clicking a button with perhaps a little finessing. After doing the keystoning, sloping building syndrome is instantly cured. If I have hard lines in a photo, my first step (even before cropping) is to keystone so it's as if the camera were looking dead on with the subject.
