How do those touting Exmor advantages demonstrate them? They underexpose by 4-5 stops then push the shadows back up. While there are valid reasons to do that, it's an 'advantage' that's totally useless to the vast majority of dSLR buyers.
A lot of people do just that, yes. However, I have been showing examples where underexposing was a necessity. I'm an "afternoon landscaper"...I can never get up early enough in the morning (which is really early, like 3:30am), in order to be able to drive out to the kinds of beautiful landscapes I want to photograph, but get there in time to set up and be ready to go by the time the rising sun lights the clouds afire with color.
So, I'm stuck taking my photos in the afternoon, when the setting sun washes the clouds in color. Problem is, all the mountains are to my west, same direction as the sun.
As I stated, there are
valid reasons, albeit very rare ones. In your case, not strictly a necessity, since you could
get up at 3:30a but don't want to.
Consider the USA – what states are immediately to the east of large mountain ranges? Yours, Nevada, etc. Tiny fraction of the US population, so even if there are the same per capita number of landscape shooters, that's not many people.
That's really the whole point here...the number of people who require (or believe they require) that kind of shadow lifting capability is minuscule relative to the dSLR market.
