[QUOTE="Dave_W, post: 133199, member: 9521"] The default setting on the D800 for NR is for exposures of 1 sec or longer. It can be adjusted, however, but I've kept it at the default because I figured it was a good place to keep it. However, when bracketing low light shots with the hope of turning them into HDRI's I've ran into the NR problem and was held up waiting for the NR to complete, thus giving me massive ghosting. The noise that comes from long exposures is slightly different from the noise of high ISO, in that long exposure noise comes from sensor heat. That said, there's really no reason to think the D800 would produce less noise than your D5100 on long exposures. My plan is to take 3 equal images, one with NR off, one with NR set to Normal and one with NR set to High. And then compare the raw output vs. the NR off with minimal noise reduction software run on it. You should do the same experiment and compare some random spot on the image as 1:1 and see which is noisiest vs. which is sharpest. From what I'm hearing, doing the noise reduction yourself will net you a sharper image as well as less overall noise. But until I do the experiment, it's all just hearsay. PS - my apologies to the OP for hijacking this thread. Edit - I misspoke when I said NR kicks in after 1 min exposures, the default is actually 1 sec or longer exposures. Sorry about that... [/QUOTE]
