Depth of field - Perou
Depth of field is the distance between the nearest object and the furthest object.

In this photo, the man is further away from the camera and the woman is closer. I like it because it looks like they are in the same depth of field but they aren't if you look closely, also with the red paint its hard to tell.

In this photo, although its the same man, Perou has doubled him and made them further away from eachother. What I like is that they are in different positions and put different backgrounds behind each person.
