That's actually contributing a fair amount to the distracting noise in the scene. And the amped-up saturation doesn't help at all, either.
Here's the image after some basic tweaking of the sliders in ACR.
Temperature: -58
Tint: -54
Exposure: +0.3
Contrast: -43
Highlights -40
Shadows: +38
Whites: -100
Blacks: -64
Clarity: 0
Vibrance: 0
Saturation: -38
Cheers,

P.S. If I were going to make something "real" of this, I'd also mask in some selective desaturation of the darkest backgrounds. b&

Just uploaded the CR2 raw files to skydrive, hope this works:
The primary shot used here at 1/1000 sec:

A slightly more exposed 1/800 sec shot taken moments apart with the same set up as the primary:

Nice, her natural grey color is more evident, but the candle is gone all green.

Ye Gods! I will not attempt a shot with these extreme conditions/settings or frame it this way in real life...but I am finding it to be a great experimental vehicle to keep learning

Here's the XMP sidecar file. You can use it to make the changes and look at what I did.

It took me a few attempts to get it to show up right. You probably caught it before I was able to correct it. Right-click and save it. Then place it next to the .CR2 file, making sure they are named identically. In the Library mode, go to the image and go to /Metadata/Read Metadata From File...

That looks pretty freakin awesome for 102400!

LOL. To test mundane stuff, they are excellent subjects: plenty of detail with whiskers etc, tonal if not color contrast.
And as models go, they are convenient and easy to find in a pinch... ubiquitous as the most common household pet in America. Easy to book a session, no need to sign releases, generally cooperative, and no need to pay them! What's not to love!!
As for the photography forum, setting the 'model' aside, the simple shot addresses high ISO/low light aspects of 5D3. Personally for me, the top left corner, pitch black in real life, was the key. It is clear much can be done with the interrelated banding/noise/color/DR issues in these rather extreme settings and 5D3 is fairly competent when pushed.

Oh yes it does really look great...time to go LR for me. I did everything in DPP until now...That is quite a great RAW converter and denoise software as I can see.

It appears that your 5D3 has the same issue that mine does... in the far bottom right corner of the image it has a more purple hue than it should. It is more noticeable in your NR 25 image. On my 5D3 it is most noticeable at ISO 12,800 and above, but sometimes at ISO 6,400.

It is a great converter, but keep in mind that a lot of it has to do with the choices I made when converting the file. The default image that comes up in LR isn't going to look much different from what the original post showed. I did about four or five things to the image in LR's "Develop" module to bring out more from the image. It didn't take me long, because I'm experienced in the program, and have a solid photography and retouching background. You'll need to play around and experiment with whatever program you use to process your images.

Stephen, thanks for sharing your settings earlier. It is really a nice professional balance between too much processing and none at all.
@Pedro: the baseline version I posted was intentionally set to LR "zero" to show what one starts out with at this ISO. Refer/download Stephen's file for settings if you end up giving the LR4 free trial a go. I highly recommend the program.

Yes, it's pretty common. I think Canon may be working on a firmware update to help with this.

There's actually a solution to that...avoid shooting moving subjects below EV -2 with a slow or long lens without a tripod, and you won't need to boost the ISO that high.
(EV -2 is much too dark to read, so it's not like this is a radical concept....)

Doesn't explain the preferential corner noise ...again these are experimental shots and most of us including me are not keen on taking candle pics at 1/1000 sec and extended ISO except for sh*ts and giggles...but still....purple noise in just one corner is interesting. It is not pervasive across the frame.
