What is a one-sentence summary of the following article?
You want to vary the point of view by using a variety of camera angles.  Use the 180 degree rule when switching angles in order to maintain consistency for the viewer.  If you have 2 people facing each other, you would imagine an invisible line between the two of them.  When switching angles, you can move within a half circle on one side of that line.  Never cross this line, or more than 180 degrees.  If you cross this line, it will appear as if the two people are facing the same direction rather than facing each other.  Eye level is the most relatable and realistic shot you can use. A high angle, with the camera above the subject, looking down on them, will reduce the power of the subject. Low angles with the camera looking up at the subject will empower the subject. Bird’s eye from directly above gives the viewer an all-knowing impression. Slanted shots, or Dutch tilts, are common in music videos.  Instead of the camera being level, it is tilted at an angle to the horizon for an off-kilter, dramatic effect. You don’t want to just leave the camera in one place when you film your video.  If you are always shooting from a distance, you will not be able to see the faces, emotions and reactions of the characters in your video.  If you are too close, you won’t get the whole picture.  Some examples of different shot types are:  Close ups have a feature of the character or object you are filming take up most of the screen and are good for detail work. Wide shots show the character or object in its entirety on the screen. Over the shoulder shots allow the viewer to experience the point of view of one of the characters because the camera is shooting over the shoulder of that character with the other person or object in their view.  Seeing a little of the other character’s shoulder still gives the perspective of that person. A cut away is used to move away from the main characters or objects and shoots something other than the subject, like the scenery or background. Once you have filmed everything from one angle, move the camera to another angle and do it again.  Film several takes from each angle so that you have plenty to choose from when you move on to editing.  This will ensure that you have everything you need.  You will be able to choose the best takes in editing. Having a lot of "B-roll" or extra footage will allow you to make more changes in the shots and angles to create variety in the video.

Summary:
Utilize multiple angles to tell your story from different points of view. Use a variety of shots to create depth and detail work. Film more than you think you will need.
