For the Preliminary Task, I had to film a 180 degree shot of somebody walking through a door and having a brief conversation. Even though the audience never actually see the person walking through the door, because it is a 180 degree shot, they presume they walked through the door because of the camera position and the way it is shot. It is effective because it makes the video look interesting and more technical if there are all different types of camera angles and shots. Although if I were to do this task again, I would add more dialogue to make the scene more interesting. I would also spend more time editing the 180 shot so it looks more fluent.
