Need a little help from the community. Thanks in advance.
I recently purchased a D810. Overall, I love it. Recently, I took an autumn afternoon shot of a tree top against a deep blue sky, at iso 400.
In the sky, there seems to be significant noise (viewed in camera at 100% zoom). I'm not tech-savvy enough to know what type of noise, but I would think that at 400 iso, a clear blue daylight sky should be virtually noise free, even at 36 mp. After raw processing (Aperture) it is the same. High iso noise is not the issue - this is low iso where I am surprised it is even there.
I've since taken other types of "test" shots and I'm recognizing the same type of 'noise' - or at least I think so.
I've looked at any article I can find about D810 noise and - to my eyes - no one seems to have an issue at iso's lower than 1000. I can't seem to 'see' the same thing in other folks shots.
So I don't know if this is normal (as in I'm looking too critically at it, or I'm imagining it?), or very odd. Perhaps I have a lemon? Maybe it's just a blue sky thing?
I'm hoping you all can take a look at the original raw image straight from the camera and give me your quick thoughts. View it at 100%.
Basically, I'm looking for either "no, that's normal" or "holy shit send it back".
