There are many reasons for shooting in diagonal frame:
- Shooting distance with the object is not long enough,
- Wrong lens
- The object is too tall as this is the tallest building in the world (at the time this picture is taken).
I think mostly its the last reason. This picture is part of my experiment using my new Nikon D600; and because it is a full frame camera, and I don’t have a wide angle lens for full frame camera yet.
