The reason you got an underexposed image is because above 1/320 (or slower depending on your camera) the shutter on your camera is never completely open. Instead, to get a short exposure, the second curtain starts to close before the first curtain has finished its travel, creating a moving slit that exposes each part of the sensor for less than 1/320 as it passes. The shorter the shutter speed, the narrower the slit.
Here's a video that explains it:#t=64
