Mise En Scene

Mise en scene 

You can see in this scene that Scott and Ramona are in love, you can tell by the positioning of the two character and their facial expression as they are both happy, the camera is just focusing on them because the whole of the background is blurred to make you focus on the two characters.

In this scene you can tell that by Scott's facial expressions is is surprised at something and the movie make you focus on his expressions and think something must be important as the background is blurred out almost as if he can only focus at the one thing he is looking and nothing else matters.

in this scene you can tell the movie wants you to focus on Ramona as the lighting is on her and the two people behind her and blurred out and darker than her, so it makes it seem as like the lights up the room with just her presence.
