Following mention made of these profiles in this thread, I've made available put my Noise Ninja profiles for the EOS 20D / Adobe Camera Raw 3.3 combination profiles here
(368KByte Zip).
The EOS 20D was set in M mode, 1/250s at f/8, and a Speedlite 580EX was used in ETTL with a range of FEC values from +2 to -3 in one stop intervals. An image was shot at each FEC setting for each ISO from 100 to 3200. Firmware 2.0.3 was loaded on the camera.
The flash was bounced off a white ceiling to avoid 'hot spots' on the calibration chart image, which was printed on glossy photo paper and taped to a door. A tripod, remote release and (not that it makes any difference at 1/250s) mirror lockup were all used. An EF 24-70mm f/2.8L was used at 50mm with no filters fitted, the hood was fitted and the lens switched to MF and slightly defocussed as per PictureCode's instructions.
Exposure used in ACR ranges from -3 to +3 in third stop intervals - a profile is provided for each Exposure setting. Exposure -3 was from the FEC +2 image with -3 stops, otherwise nothing was more than two thirds of a stop underexposed. For example, the -1.67, -1.33 and -1 profiles were all prepared from the FEC +1 image, and +0.33, +0.67 and +1.00 were all prepared from the FEC -1 image.
It may be that things work just as well, if not better, with just the 'full stop' profiles - if so, just use those profiles where the file name ends in 00.nzp. I may reshoot the -1 to +1 FEC range with third stop FEC intervals for greater accuracy, but things seem to work well enough as they are.
The other ACR settings used were pretty much the defaults:
White Balance / Tint - as appropriate (data used from the 580EX flash, double checked with a WhiBal).
Shadows 0
Brightness 50
Contrast +25
Saturation 0
Sharpness 0. I set ACR to preview sharpening only - I think that's wise if you're going to use Noise Ninja, even if you do want capture sharpening. I believe the correct workflow is to denoise, then capture sharpen using Noise Ninja's USM or otherwise.
Luminance Smoothing 0
Color Noise Reduction 25. 25 is the default, and leaving this at 25 means that Noise Ninja picks up where ACR leaves off, also images on which I don't use Noise Ninja don't acquire excessive chrominance noise.
Lens settings - all 0
Curve - Medium contrast
Calibrate - ACR 2.4, all 0 (I am intending to get hold of a Gretag Macbeth ColorChecker and attempt to calibrate ACR for my camera using the instructions on the web).
The profiles were prepared for ProPhoto RGB, but should be almost as good in any of the ACR supported colour spaces. 16 bit was used.
If you want to shoot with radically different settings to this, it's best to run a calibration chart image of a comparable exposure to the RAW file through ACR with the same settings, then use Profile Chart on the results and use that profile to denoise your target image. However, I can't easily make my collection of calibration chart .CR2 files available, as they take several hundred MBytes.
I think you'll find that these provide much better results for 20D users using ACR 3.x than trying to use the profiles on the PictureCode site, which are for JPEG, or using Profile Image. Feedback is welcome.
