Aerial Perspective is the name given to how we perceive an object being in the foreground, background, or somewhere in between. This can be easily achieved by the use of lighting and focus . Movement is linked to aerial perspective, as we also change perception, depending on whether objects are still or moving. For example, a branch breaking from a tree in the background makes the viewer look at it, without necessarily being where the action is. Different relations can occur between depth planes, so find out how films of your choice manipulate the relation of depth in the frame .
Different objects move at different times in the frame.
Thus, we are 'guided' towards certain events by when they occur. These techniques have, for example, been used in an invert manner in The Naked Gun series of film comedies . We concentrate mainly on the actors, although there are plenty of visual gags occuring in the background.
