These are both stills from the Abba video for Mamma Mia. It shows the camera going in and out of focus, thus switching the focus and attention from one person to the other. This has a great effect on the audience as the camera is almost manipulating where it wants their attention to be. I want to use this shot in our video in a scene with the main character and her boyfriend, so as to switch the viewers attention from one to the other to almost confuse the viewer and therefore portray the image that the characters are confused. They dont know what to do with themselves and are relying on eachother.
