This shutter speed is 1/1000th
of a second, so it freezes the
action.
This shutter speed is 1/10th of
a second, so it partially freezes
the action with some blur.
This shutter speed is more than
just seconds, it’s 45 minutes.
It allows so much light in, that
stars you wouldn’t normally
see with the naked eye appear.
It also has slight star blur from
the earth spinning during the
45 minutes.
