But I think this just leads back to my original problem. Where does the
light come from to take these 1/2 millisecond or shorter "slices" when
the appropriate shutter speed is 1/60 second? If it takes 1/60 second
to build up enough photons on the sensor how is it going to take
additional exposures during the shutter interval?
