I don't get the "shoot film and then scan it" thing AT ALL. There's probably some applications that make sense, and of course people are free to do whatever makes them happy, even crazy things. I shoot film, I shoot digital. I don't monkey around trying to cross the streams, though.
If you scan at a resolution higher than the median grain density, then it really doesn't much matter - at least not resolution-wise. If you print back onto a continuous tone media there isn't any objective difference. With modern inkjets having such huge dpi values, it probably doesn't matter much on inkjet either.
Sure, but if you're going to digital anyways, why not just start digital? Yes, I know some people like to switch horses mid-stream and convert and all, I know it, I even respect it. I just think it's weird, incomprehensible, and mostly crazy.
