Good example there pelebel That photo works with a little HDR. A few months ago I was toying with the idea of delving into ND filters and graduated filters, to try and get some decent contrast between dark landscape foreground and bright skies. Then I bought a G12 and found that with a tripod and sticking the thing in HDR mode, I could get properly exposed images. Not the arty HDRs, but properly exposed images. If using HDR techniques is cheating to properly expose photos, then logically, wouldn't using ND filters be cheating too? For me, personally, the biggest selling point of the 1DX is its multi exposure HDR capability.
ND filters reduce the contrast, so does HDR. Remember the days when photoshopping was considered cheating too?
I too like the HDR feature of the 1Dx, but $6.8k is too much for me
