Nikon d90 noise iso

The above crops compare the D90 top row versus the D bottom row of each set. We see very similar results, with the D having a slight but clearly discernible edge on detail at lower ISOs, and the D90 having slightly cleaner results than the D at ISO and , but with a more processed look to them.

I think your camera must do something like take a few photos then merge them together to reduce noise.

So the cost would be time. That's what commented instead of answering your post. In camera noise reduction mainly long exposure NR drains lots of battery Consider that as well. Why does long exposure NR take more battery? Isn't it running the same algorithm over the captured image no matter what shutter speed? Add a comment.

Not only can you tweak settings, you can mask the NR layer differently on sections where you want to keep more detail. Here's an example of the amount of improvement you can get: pentaxforums.

Believe it or not light can come in through the viewfinder, bounce round the pentaprism and land on the sensor!
