A couple things I forgot to mention:


Without flash you'd need at least 1/500 second shutter speed to stop the action.If you use a flash the duration of the flash pulse is around 1/1000 of a second which "burns" the action into your frame. Even though the camera is set to your maximum flash sync speed of 1/250 you will get roughly the same motion-stopping capabilities as if your camera were set to 1/1000.


You'll want to position your flash(es) high up and down if possible. I usually jury rig something different every time. I've gotten good results not positioning the flashes at a high angle but if you can go for it. Sometimes I tape the flashes to the bleachers, sometimes I use a tripod. Tonight I used a monopod taped to a light fixture taped to a railing.


Never shoot into your light source. if you position your flashes on either side of the hoop sitting under the net would be ideal.


You say you'd be shooting from the bleachers. In that case you'd put your flash in the corner on a bleacher railing pointed toward the keep.


Your going to want to use manual mode. set the shutter speed to your maximum flash sync speed (for you its 1/250) set your aperture to the lowest value and your iso to the maximum acceptable level. Then set your flash(es) to anadequatepower setting so your image is properly exposed.





Best of luck! Let me know if you need me to elaborate on anything.
