How do you guys and gals use High ISO noise reduction on the d800? Do you tend to always have it switched off or on? Only on in certain low light situations? ty!

Now this might be personal, but I've turned mine OFF. I figure that it will only affect jpegs and since I usually use raw files, the in-camere NR only takes more time before the file is saved. If you want proof, just do a few long exposures and you will realize that the camera gets extra slow between shots.

I do use the D810 but the same applies for me: NR is turned off. The NR duration after a long exposure is as long as the shutter used for the shot which becomes annoyingly long when you're shooting 10-20 or 30sec exposures.

And if you're shooting RAW, the NR software available for your computer does a better job at noise reduction than the 10$ algorithm used in-cam.

If you shoot JPEG, it might be better to have NR on.


To add: if your RAW processor supports it, you can take a long exposure with the lens cap on and afterwards use that as "Dark Frame" subtraction. That way you can still use LE-NR without the disadvantage of needing it switched on for every shot.
