I think that he's talking about direction of light guys!
The answer is that you can shoot with the sun behind you, or into it giving backlighting. If you're shooting into the sun try to make sure that you fill the frame and get the exposure right.
My mistake, i just went on from where Tug left off.
I try to avoid it but you cant always, take a look at my website and the recent England v Wales game was shot into the sun.
