| p.5 #8 · D200 Banding is real. |
experience has been broadly similar. No idea why it would affect NEFs and not jpegs, but my guess is that has something to do with the demosaicing algorithms and compression artefacts introduced by the in-camera processing.
I'm beginning to believe your guess is at least partly correct, with the demosaicing.
Just because the problem goes unnoticed, it doesn't mean it isn't there. Many D200 users won't be shooting RAW and viewing at 100%. They're still entitled to expect to be able to do so.
heh, well, lots of people have lots of expectations. Whether or not those expectations are reasonable, is another matter.
You're entitled to your opinion, of course. But I wonder whether you'd describe it as 'insignificant' if your own D200 were affected?
I'm coming to the conclusion that this issue probably affects every d200. I dealt with some files, provided by another d200 user. It seems that the issue only comes about under extremely harsh lighting conditions, with significantly blown out areas of exposure in the frame. Yes, I still describe it as an insignificant issue, at least at this point.
The problem seems to be easily avoided, by making proper exposures, under lighting conditions that don't far exceed the capability of the sensor. Failing that, the banding is easily and quickly dealt with, by a very minor application of NR.
I've described my experiences, for the benefit of any other D200 users who may be experiencing difficulties, as accurately and completely as I've been able to. I do have better things to do than attempt to track down an intermittent fault on a new camera,
That's part of this issue, IMO. You have better things to do than to track down the cause of the problem, but you don't have better things to do when it comes to bashing the camera for that fault.
I don't view that as being a benefit at all. Making a mountain out of a mole hill, isn't helpful.
But the substance remains: significant and destructive banding in some mid and quarter tones on affected images at various ISOs. It doesn't happen with my D2X, nor did it happen with my D100.
I don't have either of those cameras, but I'm willing to bet that they have their own issues with inappropriate exposures and post processing.
And yes, I'm talking about correctly exposed images.
So, where are the samples of such correctly exposed images that have this artifact?
There was an earlier poster on this thread who pointed out how irritating it is to a.) find that your new camera has a fault and b.) to be variously accused of imagining it / pointing it at too bright a light source / bringing up the shadows too much / underexposing 3 stops / not having a clue. I'm beginning to realise what he meant.
When you shout fire, you need to be ready to show where that fire is located. That's the way things work in normal life. It should be no different here.
It might very well be that your camera suffers from abnormal banding, but if it doesn't, exchanging the camera isn't going to solve anything.
OTOH, if the issue is caused by inappropriate exposure and nikon issues a firmware NR "fix" due to unreasonable internet hysteria, that is not a good thing.
