In my intro to computing class, we went over what visual story telling was. We watched a great presentation. It was all about how to tell a good story with shot composition. I had never seen the presentation before and that seemed odd because it was taken from the Hawaii Creative Media website. I guess you were supposed to watch it when you joined media at the beginners camp, but I was off island and unable to attend. I suggest you look at it even if you already have because using these techniques can greatly benefit your video. You can check it out here.
