Terror from Behind (Split Focus)
What does it look like?
It’s a shot that is in focus in the foreground and also in the background of a frame. You can usually see an out of focus area between the two sharp objects.

The split-focus effect is done in camera using a split-focus diopter. A split diopter is a device that attaches to the lens to make half of it nearsighted. This allows you to focus the lens on one object and the diopter on another creating the illusion of deep focus.

This shot is best used in moments where you want the audience to focus their attention on two areas of the frame at the same time.
