Improved S2 profiles in LR?

I am anxious to see what improvements are made in S2 conversions. Too bad I will have to wait until this evening to find out.

Jack, as I still have the camera for a few days, just let me know what you'd like me to post and I'll try to help out.
Others are much better at analyzing and quantifying results than I am. In deference to Michael Jackson "I'm a shooter not a tester."
The colors I was getting in my earlier go-around just seemed a little out of whack ... they are better this time around. How much? I don't know ... but the files are starting to excite me.

As an fyi ... http://labs.adobe.com/wiki/index.php/Lightroom_3.2
The new version adds an Adobe Standard profile for the S2, with tweaks for color and reduced color noise at ISO 640 and 1250.

Jack,
I don't have the older version of Lightroom on my computer. But here is a quick hand-held shot I just grabbed five minutes ago using my daughter as a guinea pig. It's processed using the latest version of the software. Sharpening is turned off on the first two samples. I've added a bit of sharpening via Lightroom in the third shot. The skin tone and color is looking very good to my eyes.

Maybe, but in looking at the mortar, that I assume was grey, it seemed pretty neutral, However, doing an eyedropper on it did increase the red overall.
Looks like some more tuning is needed.

Some of the model captures (of Tori and Dennise) in Jack and Guy's S2 review were processed in Lightroom and the results were posted in the review.

Maybe the easiest way to see if there are any differences and improvements would be to reprocess a couple of those files ?
According to post # 20 in the review the S2 DNG files can be found here:

Mortar is not really neutral grey, but a slight bit greenish (at least over here). That may explain what Victor noted.
Excellent call, but I'd need a current working copy of LR which I no longer have. Do you know if the latest ACR build has the same profile? I am traveling this weekend, but can certainly check it out Monday.
It's a big improvement, it seems. These crops certainly show a more neutral colour, with better handling of reds and skin tones. What is evident also in the shot with the purplish woolen jersey, the new version seems to be doing better at pulling a little more detail out of of the files.... :thumbs:

Very nice contibution; this does demonstarte the value of tweeking the profiles.
The open question is the need for a dedicated raw developer and what it would do. If the current system has a good algorithm for the Bayer Matix conversion (that is, we don't need to have a 4x4 and 8x8 etc higher order correction, that would be VERY slow) then one wonders whether profiles will close the gap.
Guy has suggested that the processor does more than color balance, and that a good raw processor also can take out anomolies of the sensor (aliasing, artifacts etc.)
What strikes me here is that the profile allso contributes to detail, by moving the color space to a point where neighboring pixels show more detail (that may have been "Bayered out")
an ultimate raw proc would treat the four inputs almost like a color space hologram, and have an extremely detailed algorithm to reconstruct. THEN it would need to filter the know artifacts of the conversions. Looks like LR has a nice compromise, but not one that digs out wha'sin the S2 files.
I must say that this could be a nice niche business; I would immediately buy a raw processor in the uder $100 range, even for casual use; ONE good print would pay for it.
So, are ther forum members who are adept?

Victor
