We have three terms for determining different level of depth in a movie shot and they are foreground, middle ground and background, but are there more words? How do you for example identify different depths within each of them, because, although very rare, we may sometimes see more level of depths than three, and sometimes in the middle ground alone we may see 2-3 levels of depths. I am sorry if I misused the term depth, but I guess most people will understand what I meant.
For example:
In the foreground of the middle ground, we see a similar element that is seen in the foreground of the background.
