For many years I was a dedicated user of Nikon Capture NX2, indeed advocated and provided intro tips on pbase.com. A year ago I upgraded from D80 to D7000 and at about the same time DxO optics did some rapid upgrade work to v7 and shortly after to v8.
For the D80, there was not much in it, but for the D7000, DxO v8 wins hands down, even taking into account that separate editing of parts of the image is no longer possible. Unfortunately my MacBook Pro 15" (24gh 2008 with 4GB RAM) won't handle both programmes at once (and of course all the other essential ones).
The D7000, and I imagine other Nikons of similar vintage, captures an exposure range well beyond what can be handled at once. The DxO exposure compensation and 'virtual' lighting make use of this in a manner similar to HDR progs, but without any of the artificial effects associated with HDR and with full user control. NX2 just doesn't seem to have the reach and, with hindsight, leaves a risk of obvious boundaries between different masks/steps
It seems tragic that Nikon can't do for its own processors what a 3rd party does by body & lens testing and an NX3 is urgently needed
BTW I have never been able to cope with the mish-mash interface of any Adobe progs and didn't think Aperture any better when I last tried it. Unfortunately one has to go there for serious cloning, the DxO heal being very weak and NX2 a bit hit and miss. NX2 totally lacks correction of verticals, which DxO does brilliantly.
