Dolly Zoom in Ratatouille

Here is a brilliant use of the dolly zoom in the movie Ratatouille. It doesn't bring attention to itself, but it is powerful.

"The dolly-zoom is generally used as punctuation (usually an exclamation point), screaming "The characters are going through something significant RIGHT NOW!" In this scene from "Ratatouille", the dolly zoom is simply part of the mise-en-scène and not the focus of the shot.

In the shot, the camera is focused on the television in the background, giving the audience important information about Remy's culinary hero, Chef Gusteau. The chef gives our hero an inspirational speech across space and time (through the television), and reminds Remy of the all-important notion that "Anyone can cook, but only the fearless can be great." The shot begins with a conventional move; the camera dollies towards Remy, with the television in focus. In the middle of the shot, the camera slows to a stop, and begins to dolly backward just as a zoom-in begins. Remy remains the same size in screen space, but the television screen blows up dramatically. A lovely feature of this effect is not only the collapsing depth (which focuses our attention), but also the ever decreasing depth of field. Remy becomes more out of focus as the shot progresses (since the focal length is getting larger), which is exactly what would happen with real-life camera systems."

Great use of dolly in and out

This is an interesting use of the dolly shot from The Wire. As the camera dollies out from one character in dollies into the other. The first character becomes smaller as the other becomes larger, signaling a shift in power.

Improv with Brandon Li

"As Brandon described, ...this technique is all about creating a film out of the unexpected, with minimal planning and forethought, and improvising when needed. Brandon often stumbles onto scenes that he wants to film. He emphasizes that in these cases, filmmakers should just start shooting to establish the scene, and then go in closer for the interesting angles and multiple takes. Brandon stresses, “Seek a moving subject and find unusual angles. If you’re uncomfortable, you might be doing it right.” Why? “It means your audience has probably not seen that often.”"
