The print (17x22") came out beautifully!
Compared to the Phase One IQ180, the D800E has slightly better dynamic range, the best for shadow.
Nowsday I bracket. For the D800E, 3 frames are usually enough. I've used the graduate neutral density filter (especially the 2 and 3 stops) only for panorama or very long exposure.
The D800E is an outstanding camera for landscape.
