High ISO Noise Reduction

I have a total rookie question, but was hoping someone could help me anyway. On my new 5d Mark II, it has 4 levels of noise reduction, but the order of their magnitude is unclear to me. For instance, the default setting is "standard" and the next option is "low", so my question is which is lower? My guess is that the order is as follows: 1) None, 2) Low 3) standard (default) and 4) High, but I would like confirmation. Also, what is the disadvantage to using "high" noise reduction? Does it lower the 3.9 fps? Thanks for your help.

Please don't take this as a smart-a** answer but... you are in the perfect position to answer these questions for yourself and other non-5DII owners.

Take the same low-light, high ISO shot with each of the 4 NR settings, bring the four images up side-by-side in Photoshop and do a critical comparison.

From my own test and other, the in camera noise reduction results in lower sharpness and the images look very waxy.

I for one turned it off and plan to post process with better software. Depending on what your workflow and if you post edit, you may choose to have this feature on or not.

I used noise nija 20 years ago and find my images very blury after processing in this tool.

since then I used Lightroom, but the noise reduction performance is not ok.

It looks like the best price/performance noisereduction is DPP:

+1....totally agree!

I have the same experiences too....so I turn this off 100% of the time.

Cheers!

Disable = no NR
Standard is in between low and strong ("medium")
Low is less NR than standard.
Strong applies the most NR, higher than standard.

I am very impressed at how well they have done the NR - it's way more pleasing to me than when I tested the D700. Even with strong selected, it doesn't smear the image the way the D700 does.
