I'm not sure what I'm supposed to be looking for.
However, one thing I saw was chromatic aberration. Try correcting for that, and see if the other problem reduces.
And maybe it is best to use a combination of settings instead using just one slider to make changes?
If you look at the tan booms on the tops of the boats, you'll see a thick outline in the fill image that is not present in the uncorrected image. I've experienced this in several images, and adjusting for the CA has little or no effect, though it does seem related somehow. I will explore it further however.
I have a tendency to use fill towards the last part of the process. I have experimented with different work patterns and still get this when using Fill or Recovery.
Thanks for the feedback.
It's beta...as in not done yet...as in Thomas and team are still working...as in wait for the final version to ship, ok?

Questions are fine. But you may get more response over in the Photoshop CS3 Public Beta Forum at http://www.adobe.com/cfusion/webforums/forum/categories.cfm?forumid=72&catid=626&entercat =y
Yep, it's in CS3, ACR, and DNG forums, as it may be due to something in one or all three.
Just doing my duty as a beta banger.
My main concern is that this may be an indication of other negative impacts of Fill and Recovery on an image that are not so obvious. These are some of the most usefull new tools in ACR 4 for my own personal workflow.
Remember that the public CS3 beta version became obsolete before Christmas of last year. Expect the final version of ACR 4 to be very different. Don't worry.
My CS3 beta version of camera raw (with all it's new options) had reverted back to the CS2 version. (lacking those options) What happened? I'm still using PS CS3.
You probably "updated" when Adobe Camera Raw 3.7 was released, effectively downgrading from ACR 4 down to 3.7.
ACR 4 is not available for download separately, so you need to boot off a different volume and install CS3 beta there, then take the ACR 4 plug-in in your new CS3 installation and copy it over to your current working CS3 beta, and finally delete the new CS3 beta install.

If you don't have another boot volume available, you'll need to uninstall CS3 beta, but DO NOT REMOVE the currently installed CS3 beta without first emailing Adobe for the uninstall script at cs3beta at adobe.com. If you don't use the uninstall script, you WILL have problems.
In case you are still monitoring this discussion, I also have experienced these halos whilst using Lightroom to edit Tif files which are both under and overexposed in the same image - that is, they are very contrasty. This experience has been subsequent to the release of both CS3 and Lightroom - which both use the ACR 4 engine, as I understand it. From my observations, the halos result from using a combination of too much Fill and Recovery but seem more influenced by Recovery than Fill. I have thought that this is not unexpected, and is therefore probably not a bug, as there must be a natural limit to how much of an overly contrasty image that you can rescue. I have been able to minimise (but not completely eliminate) the halo effect by judicious use of added Exposure in lieu of some Fill (to recover at least partially some of the underexposed regions) and a reduced amount of Recovery - and just accepting that all the highlights might not be as optimally enhanced as desired. Perhaps the halo effect produced by these wonderful tools may be further reduced in subsequent releases of CS3(ACR4) and Lightroom - a possibility hinted at by Jeff Schewe in his reply to your post.
This edge effect is actually forewarned about in the docs and has been well known since release. To be expected. Just use a judicious eye and be sure to look at shadow detail to bright light boundaries at 100%. If you see it, pull back until you dont.
There's always the alternative - Shadow / Highlights in Photoshop.
Now, this tool also creates halos, but you can use masks to circumvent them. The sliders in ACR utilizes linear data which should be better for preventing the halos, but you can not use masks.
I believe the two tools use different algorithms. I actually prefer the Shadow / Highlight tool, because of more options and smoother graduations, but must admit to using ACRs tools more, for ease.
Hi folks -
Thank for keeping up on this. Subsequent to the original post, I ran across other sites that referred to this, and they said pretty much the same thing.
One site had a well informed workflow between ACR4 and PS CS3, but so far I haven't been able to relocate it. If I find it I'll drop a note. The link above was very helpful as well. Got so wrapped up in exploring the new territory that the old tried and true got sidelined.
