Glitchy Images From My D750

[J-see]

There was someone with the same issue not too long ago but I can't find the post and how he solved it.

I remember the shot he shared was a chair against a gray gradient background.

Edit: If I remember well his problem was saving JPEG at a lower quality than max but it's not necessarily a fix for your issue. Easiest is if you upload a NEF so we can process it. If it is a cam issue, we all will have banding and can't fix it. If it is a processing issue, there is something you have to do differently to avoid it.

Mso even if I am taking shots in raw I see it in JPGs?. Whats tge advise than?

I would like to help but I don't know what is going wrong by looking at a JPEG. I require any NEF that has the issue so I can check it in a RAW editor and eventually check the EXIF data to see if that reveals something.

Ok. I'll be at home in couple of hours and I'll send photos. And you think it has nothing to do with flaring?

It has nothing to do with the flare issue. I have the flare issue with mine and it is something completely different.

This appears to be posterization/color banding.

I' red somewhere it could me memory card fault too

ok I am back home. How can I upload this big file?

You best bet would be to use drop box then post a link to the image

I processed one and yes I do have the posterization too.

The NEF itself is very underexposed and the problem has to be related to that because the more I normalise the histogram, the more the banding disappears. But I'm juggling between clipping in the shadows and clipping in the highlights. The whole dynamic range is used but the majority of the information is compressed in the shadows. The moment I decrease exposure, the banding reappears.





I still think it is related to the shooting itself and not to the cam but at this moment I really can't say exactly why it occurs.

I downloaded and edited one of your images and here is my quick and dirty final product... Total time spent, about three minutes.

I think it looks okay:

I toyed around with it and it seems the banding is related to the clipping.

Here's when I increased exposure enough to have close to no shadow clipping:



The moment I lower exposure and it clips, the banding resurfaces:

 

[pawel zygmunt]

Yeah but what if I want to have my photos underexposed? for sunests you have to underexpose for better colors ant those the lines are horrible. It shouldn't be like that. I had camera for 400 Euro and none of them issues

Maybe it's my monitor but I still see the posterization.
