Well, in reading this thread....
http://www.thephotoforum.com/forum/...6-my-ultra-low-light-test-shot-12800-iso.html



Here are a couple of shots from my lunch break at work. There is very little light in my cubicle, so the reflection you see in the vitamin C bottle is the only light source on the "subject". Also, these are straight from the camera, converted from RAW to JPEG and imported into photobucket.

First is ISO 12,800, second is ISO 25,600.

Taken with a Nikon D7000
Lens - 35mm 1.8G
FL - 35mm
shutter 1/80th (1st) 1/160th (2nd)
F/8

There is a thread over on dpreview on how the d7000 could almost be considered an iso-less camera due to the efficiency of it's sensor. An interesting read.

well at 12800 its no better as shown here than the the Sony A55 or the Canon 7D maybe a tad worse

2. Noise Reduction

3. Noise Reduction + B&W Conversion

OK, I've got a game for everyone while we're at this.

Here's some shots off the D700 :greenpbl:

I Shot RAW, straight converted in LR, and posted here. No adjustments.

ISO 25600:

ISO 12800:

ISO 6400:

ISO 1600:

ISO 400:

Than my "trick" ISO 12800 (No NR, No Software was used, this is straight out of camera):

And here's a 100% from the "regular 12800":

Than from the "Trick 12800":

Anyone know what I did?
HINT: Most Nikon's can do this.

layering exposures

Care to elaborate? like i said, no software was used. This is straight out of camera.

oh, and what I often use High ISO for:

24mm f/1.4, ISO 6400

In camera noise reduction?

 

[Sw1tchFX]

Shot RAW, so in camera NR would have no effect.

chito beach is close, he just needs to elaborate a little

Multiple exposures composed as one. just not sure how Nikon does it.

I'll play. Nikon D80 with Nikkor AF 50mm f/1.4 lens.

ISO 3200

ISO 2500

ISO 2000

ISO 1600

ISO 1250

ISO 1000

I'm dying to know how to do your "trick" high ISO with little noise.

As an aside, I have GOT to get a D7000!

There's an in-camera function that lets you "layer" two frames on top of each other. Its called Image Overlay. However, this is what I got when I tried it:

ISO 3200, 1/50, f/2.0, RAW

The same image overlayed on itself:

 

[chito beach]

In the Sony A55 I can layer as many as 6 images for twilight shots and night shots

 

[Sw1tchFX]

Yep, it's image overlay. Sony's call it "Hand-held twilight", they're point and shoots have been doing it longer than the SLR's.

On the D700, it can overlay up to 10 images, so when there's 10 noisy images stacked like what chito beach was saying, than the noise averages out since it's random, where the detail remains because it's in the same spot everytime.

Ah! My D80 can only layer two images, so it isn't nearly as effective as the D700's layering.
