If you have a workflow that works for you stick with it unless the results are poor. If you are starting with Nikon you have nothing to unlearn.
The biggest grip people have with NX2 is it isn't like the others. You have to learn new stuff and it isn't intuitive maybe. You'll have to change your workflow for NX2. Maybe how and when and the order you do stuff. It isn't great like say Bridge for 1000 image shoot. It is great if you break things down and do it in smaller piles.
The one thing I did that made NX2 a far better tool for me was to buy one of those DVD tutorials. Seeing someone use the tools, control pints, his workflow made a HUGE difference in what I understood the convertor can do. Now if I could remember the DVD name we'd be golden. Jason xxxxxx? Sorry I'm blank. Very very good though.
While it may not take you away from LR or C1 etc at least you'll get the best from NX2 when you use it. IMO NOTHING converts a Hi ISO file like NX2.
And just as an FYI, the image you see on the camera is of course the jpg embedded in the NEF, the image you see in NX2 is the NEF with all the settings that made that jpg look great applied to the NEF. When you know the camera the NEFs may and can be dead nuts on.
So you set WB, contrast, saturation, USM etc etc on the camera, maybe you've made a custom picture control in NX2 and uploaded that to the camera. When you open the NEF in NX2 it is all there. Open the NEF in LR? You get what, what Adobe thought might be a good place to start from. All the stuff you set on camera is ignored. Are there any convertors that read the actual sidecar settings info attached to a NEF besides Nikon?
Plus everything in the settings menu can be changed in NX2. You shot in srgb but meant to shoot 1998? Change it in NX2. You shot standard settings but wanted a neutral instead? Change it in NX2. It is really cool to be able to do everything practically except actually reshoot the shot in NX2 as regards to how you set what.
I just shot a live band. 600+ frames at ISO 12,500. I shot B&W 'cause it looks better for the gig. If they want color all I have to do is tell NX2 I want color. I can convert the whole job to color and to any "picture control' setting I want.
I just think more people need to try it. And it costs under $200 too so.........
The 4 images below are straight from camera ISO 12,500 images. They the are embedded jpgs in the NEF file that Photo Mechanic extracted. PM also downsized them a ton for email. Open in NX2 as a NEF they look just like these. Just bigger and juicier. About all I do with these is turn off in camera USM, ,move the black slider up a hair (fills in slight noise), apply a very very fine blur (works better than noise reduction) and then using NX tool erase the blue from everything I want sharp. The blur is so weak you would maybe and I mean maybe know it was there. I then paint the USM I want on the area I want. No layers, file stays normal size. All changes are instruction in a sidecar file I can change whenever I want. I never make a TIFF unless I need PS for something.
