Ok here is an example of a building that is at an angle. Using the Straighten tool in Paint Shop Pro you can make the building look normal, but it does come with a price. If you look at the original you can see more of the doors and of course the top of the steeple but in the edited version it chopped a lot of the bottom off to make the change. It all comes down to what the photographer wanted you to see in the original image. In this example I wanted the clock of the steeple to be focused on, so this changed did not affect my image.
What you see in people is an Illusion, what you do not see is their Dark side
