A dolly zoom is an in-camera effect where you dolly towards or away from a subject while zooming in the opposite direction. Also known as a zolly, this shot creates a sense of unease in the viewer, simulates a spatial warp, and can either shrink or extend distances based on the choice of direction.
This shot is commonly referred to as a vertigo shot, or vertigo effect thanks to Alfred Hitchcock’s film Vertigo, which used the shot multiple times and to great effect.
I recognized it as being used by Hitchcock, but I didn’t know if he was the first.
