I don\'t share the notion that the photograph should look right in camera in all cases. That is a persona preference, I suppose, but I\'m more interested in producing the best possible final print that corresponds to my expectations for how the subject should look.
I don\'t have any issues with those who prefer to use GND filters, but I cannot see how this is ethically or aesthetically superior to other approaches apart from judging the quality of the resulting photograph as it hangs on the wall. To me it is a bit like the idea that, say, correcting for converging perspective lines with a TS lens is somehow better than making the same correction in post, or that using a warming filter on the camera is somehow better than producing the very same warming effect in digital or analog post.
Photographically speaking, there are some very good practical reasons to consider the exposure blending method if your goal is to produce the highest quality photograph. This method permits us to do some things that are not possible with GND filters and provides greater artistic control over the result. It can also have the advantage of requiring a bit less gear and sometimes a bit less fussing at the time of exposure, though the trade-offs usually (but not always) include needing to use a tripod and more careful work during post processing.
