Nikon D610 JPEG rendering
7 months ago

I noticed that when I shoot RAW+JPEG on my D610 on high ISOs, the JPEGs come out with this super odd, blocky, chromatic noise that the RAWs don't have. It happens whether I have in-camera High ISO noise reduction on or off. The JPEG settings are at their highest; 'FINE' and 'Optimal Quality.' anyone else noticed this on theirs?

JPG @ ISO 25600

RAW @ ISO 25600

JPG @ ISO 6400

RAW @ ISO 6400

How do you process the raw files?

That's why we use and process Raw files our selves. Vic

Well yes, that's why I shoot RAW most of the time (I use ACR for processing). But sometimes I have no choice but to shoot JPEG, and this seems way worse than it should be; even without processing there is still a distinction! At high ISOs, the JPEGs show up with the green and purple noise that the RAWs never have.

Did you try to correct that in the camera settings somehow? To little details here to have any opinion...

Probably a hot/unshielded Chip in the Camera there add this "blocky noise" when the RAW is reduced to the JPEG.

I almost never shoot in JPEG.
That is why I had bought a DSLR.
Also Nikon is not very good at in-camera jpeg processing. Well, imho only Canon is really good at it, Oly is between Canon and the rest.
The rest - Nikon, Sony, Pana - are OK moderate ISOs, but when serious NR/color correction is required, they are quite bad.
But, as I said, all this irrelevant to me, as I always shoot raw and advise you to do so either.
At high ISO, raw is a MUST.

I had made a test shot at ISO 25600.
LR4 has default NR:
Luminance 0.
Color 25.
If I set Color to 0, I see no difference to RAW except for the JPEG compression artifacts, which is totally OK for a random noise.
Setting Color NR to 25 in LR makes dramatic difference.

No, it is a typical Nikon noise. Same in the D300s and the V1 also. It is the color moire typical for Nikon, and it is a shame that Nikon does not manage to take care of that in the camera and force us to use raw and work extra just to get rid of the ugly yellow/green cast.

This is typical for Nikon. I can not for my life understand why they can't clean the files better in the camera. It is the color moire you see, it is fairly easy to get rid of it but you need to shoot raw. Same in every Nikon camera I know, you can also see it in the DPR sample images. Shame on Nikon for not handling this fairly simple issue correctly in the camera.

This is 25600, 6400

Very high ISO, I believe your raw files are being cleaned by ACR, Nikon in camera NR is on the conservative side, I prefer that rather than plastic over processed files, also when printed these would probably be ok, especially the 6400.
