1. .1 The BLUR Project Brian A. Barsky University of California, Berkeley

2. The BLUR Project2 Blur No, not remove it … add it ! Real optics

3. The BLUR Project3 Importance of Blur Real images are rarely in perfect focus Perfectly sharp computer generated images appear fake Control over what is and is not in focus is a vital photographic tool Depth of Field (DOF)
