This shot was taken with a oblique angle or dutch angle and is one of my favorite photos for its unique slant. I liked working with this angle because I have not really seen too much of this angle and it does create a very interesting twist on the chair. This angle also creates a nice contract between the blue wall, orange chair, and the darker floor all in this one angle.
Nicely stated. An oblique angle can make even the most ordinary scene interesting to look at. Use it wisely.
