Lightroom: LR4 Clarity2012 weaker than ACR 6.7 RC Clarity2012
This problem can be demonstrated with at least any RAW image:
The Clarity2012 adjustment as rendered in LR4 Release is weaker than the Clarity2012 adjustment rendered in ACR 6.7 RC. This leads to images looking different between LR4 and when using Edit In from LR4 into PS and choosing Open Anyway with ACR 6.7 RC installed, but also things look different if an image is initially edited in ACR with PV2012 set and the Clarity is set high, and then the image is subsequently opened in LR4 with the ACR 6.7 RC XMP metadata being read in.
Was the Clarity2012 treatment stronger in LR4 Beta and somehow ACR 6.7 RC got this version of the code instead of the LR4 Release version?

Or maybe it is fixed in ACR 6.7 that we haven’t seen, yet?

However, there still seem to be very subtle differences in brightness.

The former being a control for detecting subtle differences in the underlying profile conversions across different platforms.
Meaning, if you don’t see any difference between Clarity 2010 TIFs but do see differences between Clarity 2012 TIFs then there is some issue, still.

Then exported two versions of the file, the first directly from LR, and the second from Photoshop (after "Edit in PS" in LR). Loaded both back into PS into two layers with mode "difference", added adjustment layer for tone control with white point set to minimum (3). Unfortunately, I did the whole experiment in sRGB, but that should not really matter
Result for PV2010:
Practically no differences (RGB values vary around 0...1).
Result for PV2012:
Differences are there. You can see the differences also when comparing the two images side by side.
EDIT: Here are the original pictures in PV2012, first exported from LR, second saved from PS (scaled down for the forum using IrfanView, you don't need the full resolution to see the differences):
As I said, the differences are very subtle, but they are there.
P.S. Side note: At present, a comparison does not really make sense IMHO. A comparison should be done using LR 4.1 final (!) and ACR 6.7 (or ACR 6.7.1/6.8 if or when the issues with clarity artefacts and missing defringe are resolved - or ACR 7.x final).

One more question/variation, can you do the PV2012 difference w/o any lens-geometry corrections occurring--the section turned off or all the corrections turned off?
There is a current bug in LR4.1RC2 and ACR6.7 where the pre-corrected image edges seem to be used for the boundaries of the various PV2012 toning operations, in case that is really where the problem lies.
