Catching the face
This was shot at the Boston Marathon. I really liked the determination in her face.
When I started shooting I had my camera set to Raw, but the buffering took too long so I switched back to jpg. I took some test shots and made sure that the exposure and white balance were correct.
I set the focus to image tracking (AI on Canon) and then I kept firing away as the athletes passed by.
