Re: Here's The "Party Trick" Explained

In that way it's a "party trick" in that you can get the same result by taking two separate exposures, 2EV apart, and combining them later on in HDR software.

Yes, but you cannot easily do this kind of "HDR" processing with handheld images, as you will need to crop and align them and generally have to do more work in post-processing. EXR DR does it all conveniently out of the box and keeps both exposures perfectly aligned. On top of that you get slightly less problems with moving subjects, because part of the exposure happens at the same time with EXR DR, not so with consecutive shots of other cameras.

You can achieve exactly the same result by shooting at ISO100 and DR100 and under-exposing the image by 1EV (DR200) or 2EV (DR400) and then lifting the resulting image by 2EV or whatever is required in post processing.

Yes again, but try to do that for JPGs, especially directly out of camera. So again, it has its uses and calling it a "party trick" may be putting it in worse light than necessary.
