Is this normal for D700?

[qwerty02]

hope reps give you a delighting solution.

I thought "delighting you always" is a Canon slogan. Or is that a hint *grin*

Grouch --> Thanks for the info. The rep did clarify that I was dealing with blooming and he did say its to be expected with the camera. What I'm quite pissed about is the extent to which the blooming is present

Exposures as follows:
Lamp Posts: f/4.0, 1/50s
Ships at sea f/4.5, 1/3s

Both shots at ISO 6400?

The article quoted above mention that the photosite 'overflow', at 6400 the photosite is sensitive to light. (or maybe you should just stroke it. :bsmilie: keke) thus, with an extreme point light source, the electron spills over.

Have you tried lowering the ISO and take a shot?

Chngpe01 --> Saw your deleted post. Not a defensive answer. Just had to run out to do something halfway while replying so didn't see your prior post before clicking "reply"
Grouch --> Yup, 6400. To be honest, this is the first time I've seen such problems though with the D700 even though I've shot lots of ISO6400 before at also night shots.
I'm also very pissed with the rep. Even if he is right that its expected performance of the D700, I think he also should have acknowledged the severity of the issue given that this is taken with Matrix Metering (i.e. standard Nikon metered exposure, not a manual mode) and its a pretty ordinary scene (picture a family member or friend standing in the foreground with fill-in flash. [OK, and VR or a tripod too] ) and at least offered some further course of action rather than say the photographer does not know how to use his tool properly and essentially to put up with it.

This is looking like some kind of banding problem on the sensor. As there is no wholesale report of banding on D700, I tend to think this is a sensor hardware defect and not a firmware problem. Shooting at 6400 should not get you this level of banding. The customer service person is trying to fob you off. If I were you, I will keep escalating to the manager and the manager's manager until someone listens.

Hi

If you can please arrange for the camera to be sent in to Nikon again, look for the service manager Jonathan. He will take over from there - he has be highlighted about this - hope it helps. PM me if you need any more help.

I don't think this happens to just D700.

I remember reading this in 123di (a free copy gotten years ago when I purchase my D50) that a pixel on a digital camera sensor collects photons. When the 'bucket' is full, it will overflow and clip.
Further reading reveals that CCD tends to be worst than CMOS sensor, but pushing the ISO for CMOS so high, i believe it causes the blooming issue to occur similar to CCD.

IMO, this blooming it's not an expected performance of just D700, but to many other cameras too, cause it's a sensor characteristic.

Maybe a suggestion, you could lower the ISO, increase ur shutter speed a little (explain to your familiar member that you wish to capture the ambiance light) and have a rear sync flash fired.
Hope this will reduce that light streak?

My 2 cents worth

 

[qwerty02]

Wow! thanks a bunch, Chngpe01! Really appreciate it!
I'll prob head over Monday when I have a break
I first noticed this when starting astrophotography, which is of course the imaging of bright points of light (and rather dim objects) against a dark background but I've never had this problem before when I used to take photos of the lights off Bukom from Labrador park with my 'ol D70, which is why I'm so surprised. Oh well.
And I've been a Nikon user for more than a decade now (amateur of course) so I hope I'll get a good reply cos' I still believe it is good equipment

Jonathan has been very responsive to many Nikon users' concern. I am sure he will take good care of the issue TS is facing.

When you do long exposure, did you close the viewfinder curtain to prevent stray light from entering and affecting the meter reading?

 

[qwerty02]

I think the lamp shots were done with viewfinder curtain closed. They're not long exposure but I've heard closing the viewfinder curtain sometimes helps so I tried. No joy.
I also tested it over a 10s exposure, again no joy. Lines.
Ah well..... I'll definitely be glad to hear what Jonathan has to say and I'll update everyone on his reply
BTW, NICE TO MEET ALL OF YOU!!!! Newbie here.... heh heh..... at least to clubsnap

 

[JacePhoto]

erh, what lens are u using? plays an important role also....

 

[sf_kang]

Wow...that looks pretty bad....I have taken a few thousands shots with my D700 now and never noticed that....but having said that.....it's still early to say yours is definately faulty unless you put two camera in the same spot using same settings and lens to shoot same scene to compare :sweat:

I concur with big kahuna. There is definitely a problem with the sensor or image processor... likely to be hardware problem. I have shot 20K+ shots with my D700 (many are night shots similar to yours)... no such 'banding' problems.

Insist that NSC attend to it. Escalate the matter if necessary.

[soeypixels]

should be sensor problem

TS: Did your software unknowinglyg post-process the photos?

From the photo of the sea where the waves are not motion-blurred, these are probably not long exposures.

I have experienced the same banding before when I opened my severely underexposed shots in Adobe Camera Raw. The software was unwittingly set to compensate for my underexposed shots, trying to "lift" details from the black when it was just way beyond the dynamic range. As a result, the banding (which is native noise to sensors and not visible if the shot is correctly exposed and no PP done) shows up. When you save the output as jpeg, the banding is recorded in the jpeg.

If you are not sure whether your software is compensating, leave the photos on the CF card and view them (1) on the camera LCD and compare with (2) the one you see on your PC. If the one on your PC is brighter, chances are your software is making adjustments in the background and causing the bands to show up.

Hope my explanation is clear enough

 

[geraldkhoo]

Looks like this is something that has been discovered by others before...

http://photo.net/nikon-camera-forum/00TTdv

It seems like the banding appears in high-contrast underexposed situations with high ISO.

Just do a google search for D700 banding and you'll find more posts...

Hi,

Encountered this too, but I have only noticed this at very high contrast, high ISO settings.

ISO 25600, 50mm, f1.4, 1/15




Should I send it in for servicing?

This is normal at such high ISO.

Is this a photo of an SAF exercise? If yes, suggest that you remove the picture.

 

[Sessantasei]

I have faced the same light banding problem as in your photos with my D700, realised that this occurs when I was using very high ISO while shooting in the dark with bright point sources. Perhaps trying with a lower ISO but longer exposure time might help resolve or reduce this problem.
