ISO 25600 on the D700

A little bad news, is this the banding issue many discussed about in international forums?
11. ISO25600 original shot direct from D700, resized
12. ISO6400 original shot direct from D700, resized (much better)
What do you expect .............it's at ISO 25600 .................. how many will shoot at this level ?

I am afraid it is. Banding is an issue with recent camera bodies from Nikon. My D3 exhibit the same problem as your D700 at highest ISO.
Like what other bro says, dun think many will shoot at such high ISO.
ISO 6400 is more than enough for very low light shoot... at least on a hand held basis.
So banding or no banding at high ISO... no issue.
What you guys think?

The only time I can think of using Hi ISO ie 25600 is when doing Private Investigation job (I used to be one).
IIRC I was using ASA 800 or higher film(I can''t remember exactly) and have to shoot at very low speed and as long as can recognize the features and positively identify the person can already, (also using 300f4 smaller can hide). Had even have to think of creative ways of eg, driving another car with hi headlights to shine pass the subjects while quickly snapping from another hidden location :bsmilie::bsmilie::bsmilie:
The recent development of D3 and D700 (with image authentication) really makes things very very much easier.
Those having affairs, beware the D700 and D3 are here :sweat:

Unfortunately, it is still possible to get banding problem even at ISO 3200 if we try to recover from the shadow portion like in this pic.
Now, I am gettin worried. I do shoot at ISO 3200 sometimes. Is this prevalent in the D3 at this ISO?
I want to do a test on mine. Is there a particular method to shoot so that I can test whether there is a banding issue?

Don't need any particular method at all. I just expose normally and tried to get more details in the dark skies by playing with Shadow/Highlight in Photoshop. The original pic is this one:

In other DSLRs like those of Olympus, you actually have to severely underexpose by at least 2EV at high ISO and then try to recover before you get such bands. And they say that Olympus DSLRs are bad at banding...

Shooting at ISO 3200 and 6400 on the D700 do not give you any banding. If so than you have to bring it to NSC.
What Tomcat is showing is that:
IF you take any properly exposed image shot at 3200 or high (without any banding seen), using photoshop or any other software, when you push up the exposure digitally there you will see the banding. Actually this is the case for even ISO 200, try pushing up the exposure on photoshop of a properly exposed image taken at night at ISO 200 you will see the noises and grain etc..

That's true.
The saving grace with the D700 is that it is so good at high ISO that we don't really need to use workarounds like under-exposing and then pushing in Photoshop to get higher ISO images. Then again there would always be people around who would 'torture' an image, be it from the D700 or any other make of DSLRs, to an inch of its life just to show that banding exists.

Very true agree
The 3200 & 6400 shots look good to me. In the condo? shot, there doesn't seem to be any more detail to be pulled out. The original already looks bright enough to me, for a S'pore night sky. What I conclude is that you need to nail the exposure for the parts of the pic you deem important, so that you don't have to pull out detail and noise together. Thanks for the pics ppl.
it could mean that the people at Nikon are really pushing the processing of the signal off the sensor to the limit, squeezing every last bit of info out to the point that pushing it abit further causes some banding... that might be how they are achieving the unprecedented levels of sensitivity for a DSLR... no right or wrong to this, each company has its own way of doing things... but as long as the properly exposed images show no significant artifacts (and it is only at high ISO), shouldn't be a major issue...In other DSLRs like those of Olympus, you actually have to severely underexpose by at least 2EV at high ISO and then try to recover before you get such bands. And they say that Olympus DSLRs are bad at banding...
big issue. so very very obvious :nono:
not a case of sour grapes here, just MHO. some say it may be firmware so stay tuned.
really hope they get it fixed. but it's just as well there's obvious banding so that shd save me from having to fork out $$$$$$$$$ :bsmilie:
