You have two shutter curtains, an opening one and a closing one. At
short exposure times the closing one starts to close while the opening
one still hasn't opened the whole sensor. At very short exposure times
it's just a slit between the opening and closing curtain which moves
across the sensor: http://www.youtube.com/watch?v=ptfSW4eW25g
The shortest time where the sensor is full open is the shortest flash
sync time. Usually that's 1/250s for decent DSLR's.
