and remember filesize is affected by the SQUARE of the scale: if you
go for 50% scale, the resulting bitmap shrinks to a QUARTER of the
size.
in general, the megamegapixel pictures you get from modern digicameras
are hardly ever needed (in my opinion) are hardly ever necessary
unless you're printing wall-size posters. somebody more expert than
i could usefully give us a formula to follow.
