Shooting with Rule of Thirds:When shooting with rule of thirds, make sure to line up one of the borders with their eyeline so it will look more interesting. Never place the subject in the middle of the frame.
Rack focus is focusing lens from one object to another to make the scene look more interesting. It makes sure the audience is aware of the object that is being focused on.
180 Degree Rule:
Make sure the camera is always on one side of the 180 degree circle, if you go on the other side and cross it then you will confuse your audience and make it look strange.
