Second Early Morning Photo Shoot at Track

Today I went out early to shoot at the track. I experimented with the ISO (between 400 and later 1600). Then I adjusted the aperture to wider than yesterday. This was the result.

I like that I have captured more of the elements and the image definitely has a mood. You know it is morning training at the Oklahoma.

I just wish I got more detail in the activity at the training gate. Any suggestions?20130926_6544
