As you probably recognize, cutting resolution down by half also reduces
the amount of data to one fourth, so it takes about one forth the time,
and takes up one fourth the storage space.
And of course, reducing the bit depth by half, also halves the file size
again.
I'll leave the medium format scanning issues to people using those
scanners.
