znalazłem ciekawe odpowiedzi na pytanie View czy NX2 na: forum: photo.net/nikon

"which is better, ViewNX or CaptureNX2, for converting RAW to JPG?"

a) "CaptureNX2 is by far the "better" program in terms of making adjustments to the images, but ViewNX is quite adequate for simple conversions. Both can read the Picture Control camera settings and apply them to the output(...). Without this control, you are losing much of the capability of the Nikon system."

b) "Both programs use the same raw conversion engine, i.e., the same de-mosaicing algorithm, but Capture NX2 offers many more possible adjustments. So, if you need only the very limited adjustments available with View NX, the two programs are identical...neither is better. If you need more sophisticated editing, then Capture NX2 is the clear winner."

c) "ViewNX does not shine in conversion because it does not allow enough negative exposure compensation: the limit is -2 but I'd need -3 or even -4. So one needs to do pseudo-HDR to process such images"

wygląda na to, że w zakresie podstawowej konwersji efekty powinny być identyczne w View NX i w Capture NX2 i...
wygląda na to, że sam sobie odpowiedziałem ale może komuś się to jeszcze przyda
