In my media classes we have began to explore certain rules that you have to follow when creating a short clip or music video.I found that the most important rule that must be followed at all times is the180 degree rule.This rule states that that you must not rotate the camera over 180 degrees because if you do it gives a unrealistic view of the scene  you are filming as a person cannot rotate their head the full 360 degrees.To help me when I filmed I placed a line of tape half way across the area I was working in to remind my self that the camera angle must not pan across the line.
