Shots have more impact when you have the face of the player with the ball.
Flash shouldn’t be used (very distracting to players).
You could crop the photo tighter, just down to the player and the basket.
You could get away with a higher shutter speed, and higher ISO (1600).
Nice image that you caught him in mid-air though.
Hopefully those comments are somewhat helpful. :roll:
completely new to this whole area myself too but i found that i had to use flash for basketball. nikon kit lens will just not cut it. begining to realise that a smaller aperture is essential
