Lecture 16: Cameras and Lenses (93)

It's interesting to draw the connect here between real world photography and computer graphics. Photographers use depth of field to create focus, and motion blur to tell stories. So do animated films, games and CGI trailers! In modern games, depth of field was also used as a back off from rendering large amount of object. We can just render the main character that is close and all the background elements are blurred out to direct the players' attention and also save texture loading.
