David,
What sync speed do you typically use for HS basketball games? Do you mix ambient with the flash? What do you place your flashes?
I know with powerful strobes, NBA shooters can shoot 4 to 6 stops below the ambient at ISO100. But with less powerful battery powered flashes, I am not sure one can rely on the flash alone.
That brings us another problem. Most Canon DSLRs are CMOS based and do not have the electronic shutters so the x-sync speed is low, like 1/250. The 1/250 shutter speed cannot stop the motion. Using high speed sync (FP flash) is not an option for studio strobes or Pocket Wizard triggered flash units.
Even though the high speed sync is possible, the battery powered flash (ex. 580EX II) will not matter much when mounted far enough on the stands.
There are two possible scenarios.
1. With the high shutter speed and high speed sync.
2. With the low x-sync and use the flash to stop motion.
With #1, the flash cannot be mounted too far away.
With #2, the ambient cannot be mixed in or ghosting will occur.
Can you share what setup and setting do you use?
Thank you.
