So one of the virtues of "medium format" sensors is huge amounts of dynamic range. 15 stops! Holy crap.
Here's an serious question. What on earth do you do with that?
I know what I would do, which is to be even more slapdash with exposure than I am now, which is rather slaspdash. I'm pretty sure that's not what the people who buy digital MF systems are looking for, though. The point here is sort of the opposite of slapdash.
Output media are 10 stops, more or less at most. So you've got to map those 15 stops around a bunch, somehow. I guess you could do anything you like, but what do people actually do? Do you just fine-tune exposure in post, and then crush the extra stuff into the toe and shoulder rolloff, like film does for you automatically? Does it get rid of the "digital-looking highlights" thing for you for free?
