POINT OF VIEW SHOVEL SHOT

A point of view shot (also known as POV shot, First-person shot or a subjective camera) is a short film scene that shows what a character (the subject) is looking at (represented through the camera).
This shot where Vince Gilligan decided to show Jesse interacting with the "Meth Heads" really adds depth to Jesse's knowledge on how people think when influenced by drugs. This Point Of View shot is interesting because it gives veiwers a unique perspective on such a basic action.

POINT OF VIEW COMPILATION

Fans of Breaking Bad have probably noticed that there seem to be cameras affixed to pretty much every stationary/inanimate object surrounding Walter White, Jesse Pinkman, and others, from the one that lives inside Walt’s washing machine to the one that sank to the bottom of his pool to the one stuck to the end of Jesse's shovel. Yes, Breaking Bad loves its POV shots, as evidenced by this nice compilation video. Love you, Roomba-cam!

MOTIVATED DOLLY SHOT

In the final episode of BREAKING BAD...there are two shots in a pivotal scene that are perfect examples of how to use camera movement to amplify the narrative and surprise the audience. With one simple pan and one simple dolly...there is a set-up and shortly after, a dramatic pay-off. The scene at first appears to be just conveying information to the viewer. Then, with one pan and one dolly move...the scene is flipped on its head and is seen in a whole new light. This could only happen through writing, direction, set design and camera movement working in unison. A Steadicam or crane shot through a window could never have achieved the emotional impact of a simple pan and dolly.

UNIQUE PRACTICAL EFFECT

*Disclaimer*
This scene contains drug use and may offend some viewers

While chromakey would be possibility for a scene like this, the overall aesthetic of Breaking Bad used a combination of real locations and studio work. That doesn't preclude using green screen. The actor Aaron Paul was actually on a gimbal that was raised mannually from the bed, which created this magical illusion.
