It's not normally a talking point, this CaptureNX2 updating process .. usually due to the lack of new features, or any improvement on the old features workings .... But!
CNX2 updates usually only involve added camera support for the newly released camera bodies and the odd bug fix or whatever(OS support update, etc), but additions and improvements to feature set are few and far between.
But!!! .... this update to v 2.3.5 could be a worthwhile waste of bandwidth for some of us.
If your usual workflow is to use as little software as possible, and in trying to do so, you're also unimpressed by the lackluster noise reduction tool in CNX2 .. well there's a slight change.
Well, that's sounds almost like me, but in the new v2.3.5 update to CNX2 is a new noise reduction feature.
Where there were two options for NR(in CNX2), now there's three .. Faster, Better Quality and now Better Quality 2012.
Had a quick play, compared a newly captured image at ISO3200 on the D300 just to see if there's any reason to use it, and it looks perfectly fine.
AND!!!! to top it off, NR is now a lot quicker to process too.
I've always found CNX2 to operate quite quickly on most of my PC's, and the latest version similarly quick .. but NR on the other hand has always taken it's sweet time about crunching it's numbers.
The faster option has been just that .. faster, but pretty much useless as an NR tool on any image above base ISO!
The best option was obviously Better Quality, but even this wasn't massively impressive in it's ability, such as LR's NR tool, or something specialised like Neat Image .. etc.
But this new option give better results than the old Better Quality option of previous incarnations.
Not the same level of performance as dedicated software, but at least giving LR a run for it's money.
Nikon Capture NX2 update
There is an update to ViewNX2 in there as well (updated to v2.6.0 now), but no fantastic or even basic elementary features updated or added .. ie. these NR tools in CNX would be nice to see in VNX2 too!
