Lesson 4 - Shutter Speed

Being able to stop a speeding tennis ball or a horse chasing down a calf, requires a fast shutter speed. Each of these was shot at 1/500th second and f/2 at ISO 200.In each of these situations, the shutter speed coupled with a large aperture, provided the impact I wanted.The large aperture allows me to concentrate the attention on the tennis ball and player. The line umpire is important to the image, but is secondary.Therefore, using a shallow depth of field allows me to throw him out of focus and yet use him to make the image memorable.   shutter-speed-dof.jpg    shutter-speed-dof-2.jpg
