I'm fairly short only 5"6 and I usually shoot at my eye level looking through my lcd viewfinder. I know there is a certain angle to be when your trying to create a dominant look or weak look(high/low angles) but what is a good rule of thumb where the camera should be for regular composed shots, such as a dialogue shot. I feel like my composition is never what I visualize in my head, still trying to figure out what's wrong.
