Iso 25,600

[Wes]

Here's a quick snapshot of my son. The lighting in the restaurant was horrible so I thought I'd see what ISO 25,600 looks like on my D3. As far as images go, it's junk. However, I was blown away by the quality that I DID receive. The image below is totally unmanipulated except for RAW-JPEG conversion and resizing. I doubt that any other DSLR around would have been able to pull off this shot.




The only limiting factor to the D3 that I have found is me.

If you get a chance, I'd love to see what some processing would do for it (noise reduction, sharpening, curves, etc.). I have a feeling it would make a pretty decent image, other than he looks like he's saying, "Dad, put the camera down! You're embarrassing me!"

[Wes]

Actually, he doesn't mind having his pic taken at all. This was one of those times when I already had the camera on him but he was looking the other way. So, being the subtle dad that I am, I yelled across the room, "Yo!". He turned, I shot. He does have that deer-in-the-headlights look about him.

I'm still blown away with the straight-out-of-the-camera quality at such a high ISO. My D200 would give me worse results at ISO 3200.

The D3 doesn't have an ISO 25600 setting does it ? I will assume you are setting the ISO at it's maximum in camera value and then asking it to overexpose a couple of stops ?
I'm not sure this is really the same as ISO 25600. Perhaps some pixel peepers can set me straight ?

On the d3 you have what they call "HI 0.3" "HI 0.7" and "HI 1".
You have to turn it on like a custom function on the Canon's.
It doesn't actually say ISO 25600 on the camera, but the EXIF should still say 25600.

It would be the same if the math is done right !

Never trust the math of a photographer {esp if reciprocity is involved}!!

ISO 6400 is where I think the D3 rocks!

Yup. Jake hit the nail on the head.

[Spec A!]

Heh, looks just like slightly pushed Fuji NPZ. Man that is unreal.

[AndrewCCM]

Looks similar to the MKIII ISO6400...
Nice Wes...

[CaptainTom]

I guess I'm still thinking like an old geezer from film days.

If you took ISO (ASA) 400 film and push processed it to say 1600 or 3200 it wasn't the same as using a higher ISO film.

There's no doubt the D3 rocks in the high ISO realm.

The thing to watch for w/ High ISO is Blown out Highlights ....
ADR is like Ansel Adams in software ... where you go n - xxx in dev time.

Wes ... you prob did not use use ADR in this situation
unless the D3 uses it automatic in Hi xx mode. {Right ???}
The exif data only says 25600 and nothing about ADR or Hi comps.
With increased software ... increased exif should also come ...
Note - reciprocity can be a two way street esp with Small sensor P & S
but should not effect the D3 at these speeds or in the lighting above ...

Tom - you and I both. But its more sensor size that effects sensitometry
and reciprocity. Not all films did like you mentioned above.

Andrew - What does 1DS MIII have in ADR ??

Perhaps we should move ADR to a seperate thread ...

Okay, going to show my stupidity here, but what is ADR?

And u shoot with a D3 ????
Typical Nikonian ...

ADR = Advanced Dynamic Range or ... Adaptive Dynamic Range.
Nikon calls it "Active D-Lighting," which makes no sense. I'll pass on Nikon's words. When you read "ADR," you'll only find it in your D300 or D3 menu as "Adaptive D-Lighting. You could also call it "Adaptive Dynamic Range Accommodation" (ADRA), but few should venture there.

It adjusts the highlights to a lower exposure and increases exposure in shadows.
Kinda like 1 shot "Instant HDR" and maybe the ultimate digi cam feature.
I don't use Nikon Digital but know you have to turn it on - is yours on and is it always on with Hi 0.7 Hi 1 etc (???)
See your friendly Nikon D3 manual ...
