Why I'll never be a sport's photographer.

Our assignment was to photograph a moving subject using fast and slow shutter speeds. As instructed, pre-focused on the bag in front of him and did a pan and scan technique which basically meant that we were moving with him and when he reached the bag, we pressed the shutter to get a perfect shot.
And as you can see, failed miserably.

This is one technique that I must keep on learning.
