... well, I had a realisation just recently. You could scan them all and combine them via frame averaging to minimise graininess. Of course the tighter your bracketing, the more useful the result. But, it's worth a thought. I have no idea whether or not this is even necessary, given the seemingly very advanced NR in DxO PhotoLab. If anyone has actually tried frame averaging their film frames, do let me know. I'd like to see the end result.
