Vertigo Effect

This vertigo effect was first used in Alfred Hitchcock movie vertigo 1958. It is also known as dolly zoom, back zoom travelling, jaws shot or contra zoom. Believe me, I have been wanting to know what sort of shot this is and finally I got to know the name of this shot. It is very effective in expressing shots that are dramatic. The diagram below shows how it's done.


Still trying to perfect this with my Sony. Hmm...i wonder who will be the victim for pulling and pushing the dolly..hehheheheh
