One of the benefits of NX2 is that, as in the introduction gallery, you can get good results easily - but you can get even better results, but less easily, by embracing curves instead of being frightened of them!
The steps used in this gallery may seem complex, but should be compared to the techniques of blending and HDR used in Photoshop. Nikon tuck a lot of spare info into the back of a nef and only* NX2 allows you to utilise it fully.
Gallery under construction: more examples coming soon, please call again
...but meanwhile remember that in NX2 you work as in shooting with your imagination and intuition. This is to help you to do your thing your way, not to do it mine
*DxO optics RAW converter also has the genuine Nikon toolkit built-in + some 'real life' corrections for actual cameras and lenses. However once you press the 'proof' button and, subsequently spend hours in Photoshop not getting quite what you hoped, you have to go back, tweak in DxO, re-proof and start again. In NX2 you can access every bit of it all the time all with just 1 file half the size of a .tif, never mind .psd, from which you can also print. Using the 'smart object' protocol in CS4/ACR, you can return to editing the NEF while keeping PSD layers, but ACR uses a generic RAW conversion procedure, not a Nikon specific one. .
