Buschmaster,
I am not expert but what settings were you using?? I have taken several pictures of my nieces games this year and have learned a lot in the process... You may already know this so bare with me..
ISO 800 and 1600 from what I have found does cause less blurring.. but also doesn't allow for as much light. ( I dont use flash ) but I can adjust the light in PP to where it should be.
I also use multiple exposure modes.. So I can follow a player (by scanning) and take 3 to 6 pictures and usually atleast one of them will come out the way I want.
Someone once told me to not zoom in as much on a picture. For instance have half the court of so in your view and then take a few shots.... Because Digital takes a nice big picture often time you can crop down and still have a good quality picture of something that is happening off the ball... I get to carried away watching to game to try this..
As far as your pictures go I like them.. I really like the b&w with the the color in the middle.. I need to try that...
Oh and also... with one of the your last pics of the guy making the layup... Try to avoid the crowd in the background because (with most of my pics) the crowd becomes the focal point (unless you are scanning) and the player becomes blurry..
I hope this helps... Good luck and I look forward to seeing more of your pics..
