The 180 Rule

The 180 rule is an important thing that I need to take into consideration for future filming I will be doing to ensure that it looks professional. It ensures that when filming two characters, they will always be on the right side of each other. The main idea of it is to not cross over the imaginary axis (the crossing line), as shown in this picture. If you do cross over the axis, then the new shot from the opposite side will be called the reverse angle.
