I didn't have enough light to freeze anything, so I tried to take some motion pictures.
There was too much background nonsense - fences, bleachers, lights, etc - to get anything decent.
I decided to shoot feet in motion so that I wouldn't get any of the background clutter.
I now have enough pictures of feet that my older son is convinced I have a foot fetish
Tried speeds ranging from 1/8 to 1 second.
I found that all the best pics were 1/5 to 1/6 second, regardless of f-stop, zoom, lighting.




My younger son in black & red. Had to throw this one in.



To keep it fair, my older son in blue from another night on a different field
