By closing the aperture down on my camera lens to a tiny hole at F22, I knew I could create hundreds of little star shapes on the surface of Lake Michigan today while photographing at South Haven, Michigan. Because so little light was entering the tiny hole in my lens, I needed to bump up my ISO to 800 in order to get a fast enough shutter speed to freeze the motion of the rolling water. We teach all of our workshop students to operate their cameras in full manual exposure so that they can be in control of how their photographs look and feel. F22 at 1/2500, ISO 800, 70-200mm lens at 200mm
