I wonder if it's that big a problem to do. The add-on hack software for
various Canyon digicams adds a DOF calculation that may be displayed on
the LCD. It also adds a flashing 'zebra' display of highlight clipping
areas.
I doubt if it could extend to Dan's idea on those cameras, but it
certainly shows that there is quite a bit of processing power available
even in very modestly priced cameras.
