Nikon D600 High ISO NR
Nikon D600 High ISO Noise Reduction
The Nikon D600 offers four High ISO Noise Reduction settings: Off, Low, Normal (default), and High, allowing the user quite a bit of flexibility in choosing how to make the trade-off between subject detail and noise levels in JPEGs. The Nikon D600 manual doesn't say at what ISO High ISO Noise Reduction begins to be applied, so we've included crops from ISO 50 up here. Note that the Nikon D600 manual does say when Off is selected, noise reduction is only performed at ISO 2,500 and higher, and the amount is less than Low.

As you can see, the High ISO Noise Reduction setting has a noticeable effect at ISOs as low as 400. At higher ISOs, the trade-off between detail and noise the four settings offer can easily be seen.
