I have posted a zip file containing updated "Camera" color profiles (Camera Standard, Camera Neutral, etc.) for the Nikon D3 and Nikon D700. The zip file contains a copy of the readme, but I'll post it here for convenience, too:
BETA RELEASE NOTES
----------------------------------------------------------------------
Overview
These updated Camera v2 beta profiles for the Nikon D3 and Nikon D700
are designed to reduce banding and highlight color artifacts. Note
that highlight areas may appear a little brighter compared to the
earlier profiles.
----------------------------------------------------------------------
Installation
If you are on Mac OS X, drag the "Camera v2 beta" folder to:
/Library/Application Support/Adobe/CameraRaw/CameraProfiles
If you are on Windows XP, drag the "Camera v2 beta" folder to:
C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\CameraProfiles
If you are on Windows Vista or Windows 7, drag the "Camera v2 beta"
folder to:
C:\ProgramData\Adobe\CameraRaw\CameraProfiles
Note that the above path on Windows Vista and Windows 7 may be hidden
by default. Check your folder settings.
----------------------------------------------------------------------
Feedback
The profiles are currently in beta status. Please provide feedback via
the online Adobe user-to-user forums here:

VitNovak,
Very interesting. Thanks for your reply.
I'm not a programmer so excuse me for dumb questions. So i open a
Camera standard canon profile in Sandy's utility dcpTool and open
adobe standard for nikon? Or camera standard v1 for nikon?
So maybe in time you can do this conversion in the new workflow it
will be even more precise.
I so what is the bottle neck with the big profiles, can't Sandy's
utility open them?
Thanks again, im going to try this.

dcpTool is a command prompt utility.
First, you have to convert both profiles to text files by using dcptool (Sandy calls it decompiling).
Syntax is dcptool <profile name> <output text file name>
Then open both text files with text editor and make modifications I described (you need to copy-paste several lines from one file to another)
After saving resulting text file, you have to convert it back to dcp using dcpTool again (Sandy calls it compiling)
Syntax is dcptool -c <input text file name> <profile name>
dcpTool can open "v2" profiles, but workflow for these profiles is different (whole conversion is de-facto performed only by using lookup and tone curve table),
so combining them the way I described won't give desired result

Thanks Vit,
So i understand you used another method for your profile. So would it
be possible to make Canon <-> Nikon conversion in this more
sophisticated way?

Ps,
I do like what you did with 400d profile. It opens up the image. Better blue's, dark tones red's are better so granddaddy and kids don't look like apples.
Is this how you did it with Sandy's util?

My "v2" profile for 400D is made from the scratch. I wrote my own code for calibrating and my own test chart with about 1 million of different colors. Displayed test chart on a crt monitor, took 7 photos of it with 7 different exposures (0.5 EV appart), to cover dynamic range of the sensor, then calculated a profile from the difference between jpegs and raws. Since it was sRGB monitor, I had to extrapolate colors out of sRGB, but I'm quite satisfied with the result
It was not an easy task, took about a month of experimenting (+ considerably more time before that, when I tried different ways to improve existing Camera Standard profile)
My profiles for Canon compacts are more precise than this one. I used another approach (and another program) - generated test raw image (with even more different colors), saved it in the camera, developped the raw in the camera using an option in CHDK software and calculated the profile from the difference between jpeg and raw
Unfortunately, I think it won't be possible to calculate a "Nikon-Canon cross-processing profile" with either of these two approaches, as they are based on the differences between raw and jpeg output from the same camera

Wow, you dig deep. wonderful. I think you can only achieve excellent
result in this way.
So you made these profiles as an assignment?

I made this only as experiment. I was a programmer a while ago, now I'm working as system engineer, so I still sometimes want to play with some code ...
What Nikon camera do you have? I made an experimental profile for D700, just using lookup table from my 400D profile, so if you have D700, you can try to see what happens (don't expect miracles, of course)

As tone curve for 400D was calibrated to baseline exposure zero, and ACR assumes 0.5 for D700, you have to move exposure slider 0.5 EV down (left) to achieve correct brightness (and to recover upper 0.5 EV of raw data). Use blacks 0

Ok, well i'm interested for sure. I own a D700. And this one you did
copy in the way you described?
Looking forward, thanks.

It's made using dcptool with above procedure. In this case, it means that whitebalancing is done using color matrices for D700, which is ok, but mapping to output color space as if it were 400D, which technically isn't correct, as these two sensors are colorimetrically different. But I tried it with two raw samples I found on the net and result didn't look bad. Anyway, I presume that it is somewhat more saturated, compared to that what 400D would produce, and there are probably some hue shifts. Try on some your photos and see is it usable

Спасибо огромное! Я готова была уже разбить или выкинуть свою камеру! Вы спасли ее и мои нервы!
