If you have flash enabled, the camera will refuse to use any shutter speed
so
fast that the first curtain has started to close before the second curtain
has
finished opening. On my XTi that's anything over 1/200 sec.; on the 30D,
which
is a bit older, the limit may very well be 1/125. So make sure the
camera's
settings allow it to stop down enough to compensate for the slow shutter
speed, and pay attention to the warning lights.
Note that this effect has nothing to do with the speed of the flash, only
with
the fact that the shutter must be fully open when it fires.
