Whedon used a variety of cinematographic techniques to achieve the dreamlike quality of "Restless". He used tracking shots with a Steadicam to follow the characters from place to place, creating a flow in the way of real dreams, where there are no logical connections between places and things. In Giles' dream, he walks from a carnival grounds into Spike's crypt, then through a corridor and straight into The Bronze, three locations not related to one another. Whedon was able to do this by simply having actor Anthony Stewart Head walk through the sets as they were built; this effortlessly created a sense of dreamlike dislocation. Another example of this occurs when, in Xander's dream, he walks from the front of the moving ice cream van towards the back, crawls up and over some boxes, through a window, and drops into his basement. In the theater scene during Willow's dream, a Frazier lens was used to provide a large depth of field, allowing both the foreground and background to be in focus at the same time, while in Xander's dream, as he moves from room to room in Buffy's house to the university dorm rooms, Whedon used a 17 mm lens to give a sense of motion as the camera passes by walls. Whedon also used unusual framing for shots, often leaving much of the frame empty, with a character being placed near the bottom or off to the side. The scenes in Spike's crypt, part of Giles' dream, were shot in black-and-white to emphasize that Spike is seen as "an old 30s movie villain".
