Wrote a short and quick article on how to minimize noise in Canon 5D Mark ii RAW files.
Basically, you can see the differences when processing a RAW file thru DPP, ACR, and Capture One Pro v5. (RAW file from imaging resource)
I've started processing all my "best" images through Capture One v5

Thanks, Matt. Great article and just what I was thinking about the other day.

Capture One DOES make a difference, how 'bout that. This is good, it's been at least 48 hours since I've spent money on something photography-related...
Seriously, thanks for taking the time to show this, I think I'll be downloading a Capture One trial if they have that available.

I should also mention. You can tweak ACR to have more aggressive low frequency chroma noise reduction, what we see going on here ... but, in my experience, ACR will still leave some residual lumi-noise that many perceive as shadow banding. Raw conversion is usually the first step of many. Those shadow artifacts, many times, show their ugly characteristics when one starts to do vignette correction and shadow/highlight moves in post. If we can get to a better starting point off the get go, I feel the image will hold up better with additional corrections and alterations.
Additionally, It appears the default settings of C1 have not only reduced the range of hue in the leaf, but have shifted the hue value to what I would say is a bit too yellow. Is this a WB misinterpretation or a profiling glitch. Or, maybe the low frequency chroma reduction is too aggressive. With proper tweaks I think you can get satisfactory color results as well.
Finally, C1 has a noise reduction feature that is based on long exposures. It's quite useful actually.
interesting. I dont see much difference in DPP vs C1. Ill have to try a comparison between ACR, DPP, and LR2.2 (i use the latter for RAW)

One other think I've noticed is the colors in DPP are usually more accurate and pleasing than ACR. The camera profiles for ACR make a difference but still don't quite compare to the way DPP renders my files. Maybe I'll when I get the chance I'll post a comparison of DPP vs ACR on a sunset shot I took about 6 months ago where DPP rendered the colors significantly better.

Side Note, check out the new processing engine in LR3 Beta. Looks to be absolutely spectacular for those who print large. I hate how acr has used a fractal looking de-mosaicing algorithm in the past. The new option, under Settings, has a granular and less mathematical look.
Funny how the new goal is a direction that C1 has been going towards since inception. (more film like)
Here is a link to a before and after gif file that toggles:
If you haven't, you should definitely download the LR3 beta from Adobe labs and give it a try. Also, give C1v5 Pro a 30 day free trial as well. The new lens correction features are quite nice.
