"CNX2 New Noise Reduction - Better 2012" Fri 21-Sep-12 06:32 AM by DeanAZ
In my opinion this is quite a useful new feature in CNX2 2.3.4. Now there is an improved noise reduction algorithm included in the Camera Settings section.
Now we have improved granularity of the sharpness slider control on a scale from 1-100. Higher numbers affect smaller sized noise grains and lower numbers affect larger grains. For the Intensity slider it still retains a scale of 1-100 but for the previous Faster or Better settings even modest numbers eliminated detail quite rapidly. Even though the scale range for the new Better 2012 style is still the same it seems to have much finer control. I could never use intensities over 15 with the previous styles.
The new algorithm seems to retain more detail and removes more noise than any possible settings for the Faster/Better styles.
This is only available in the Camera Settings applied globally to the image and the edit step styles of noise reduction are unchanged from previous versions. I hope this changes in a future release.
I found this new enhancement encouraging as it seems there is still a light on in the software development department at Nikon. Perhaps the Nik/Google acquisition does not spell the end of CNX after all.
Here are some 100% crops showing a comparison of the different noise reduction styles.
D7000 F/2 1/640s ISO 1000 Nikkor 35mm f/1.8
No Noise reduction
Faster Intensity 6 Sharpness 5
Better Intensity 6 Sharpness 5
Better 2012 Intensity 65 Sharpness 45
Final output holds up to some sharpening without showing noise problems after the Better 2012 noise reduction applied.

Thanks for pointing this out Dean, and for your excellent sample images.
I always read the "ReadMe" files issued with each CNX update, and it's really odd that Nikon didn't mention this VERY interesting enhancement with the notes accompanying the "Capture NX 2.3.4 Updater"!!!!!!!

Unfortunately it is not odd. For example, nowhere it is mentioned that the D600 incorporates 36 new features (If I counted right), and it is not the first time. It is a regular 'thing', like if they want us to fully enjoy the pleasures of discovery.

Very interesting, Dean. Thanks for pointing this out. However, the 2012 setting only appears to be available in the Develop>Camera Settings part of the program. It does not seem to be available when using noise reduction in an edit step, which is typically where I would use noise reduction, to apply it locally. This would mean that the new 2012 setting would only be available as a global adjustment.
Am I missing something?
BTW, I just installed CNX2 on my new Win 7 64-bit box this evening. Holy moly, what a difference from my old XP box!

hi Dean thanks for the examples. it does seem to help for printing in nx2, but i find that after converting to jpeg, on screen rendering takes longer. also when and how is the astro noise reduction used? bounce
