Indoor basketball shots generally require a high end lens (and often camera body) to get sufficient light in the images. A "slow lens" like the 18-55mm kit lens is extremely limited in what you can accomplish indoors, particularly with moving subjects like at a sporting event. Pro photographers use lenses that cost $15,000+, not to mention their $5,000 camera bodies to get the results you see in magazines like Sports Illustrated. You will never achieve those results with your 18-55mm -- it will never happen. But, that's not to say you can't get some decent shots if you follow the good advice above, and perhaps try shooting with the on camera flash, and wait for a slowdown in movement of the players.
Good luck. Post pics here after the event!! :mrgreen:
Wow I have got to tell my wife about this. I only spent $7000 on my 400mm f 2.8 & $6000 on my 300mm f2.8. I need to spend more the next time.
:lmao:Seriously to the OP sports/action photography is very demanding both on the photographer and the gear. It is expensive to buy the right glass and to a lesser extent bodies. The only thing you can do is to anticipate and shoot to the strengths of the gear you have and be satisfied with the results. Good luck.
