Nice shots for your first time using flash. I just started using flash about 4 weeks ago and these are much better than my first flashed shots of the Varsity Eagles.
I have found that each game is a bit different, I finally thought I had it right two weeks ago when we played Galt at home, but then I went to Consumnes Oaks last week and struggled. I don't know if it was the lighting or what, but I hard time getting decent shots. I messed around w/ my settings all night and just couldn't seem to get it right. I still ended up w/ some decent shots, but they just were not as crisp as the prior week.
Oh well, I'm going to shoot the Folsom @ Pondo game this Friday so i'll see what I come up with.
Have you tried to mount you flash above the camera? I have practiced with it both ways and found I didn't like the monster shadows I got when it was mounted below.
