Clive, with my paper negatives, I'm exposing them as if they had been pre-flashed. So the total exposure to all light is the same either way. I don't think this is analogous to post-flashing while making an enlarged print, unless the print is intentionally underexposed before flashing...

I'm curious about this too... I'll check out Les McLean's site.
