Yeah, I've set the defaults for both colors to 1 with some non-standard color-ranges and that seems to be getting the job done as well as the fixed control before.

Interesting how little discussion of this there has been.

Hi Rob,

Camera Raw 7.1 finally presented the controls to us Photoshop users that you were talking about the other day in the context of Lightroom.  And now it's clear what you were talking about. 

What you say makes sense, though what doesn't make all THAT much sense is a design that presents one color-range for one set of controls but unconstrained color for the other set.

Okay, I've had more time to look at this...  It seems to me that Photoshop CS6's Camera Raw 7.1 beta is not as good as its predecessors at achieving a balance between good color and defringing.

Note the following three images, excerpted from a Canon 40D raw file, which can be found here.

Converted in Ps CS4, ACR 5.7:

Converted in Ps CS5, ACR 6.7:

Converted in Ps CS6, ACR 7.1 beta:

The specific color fringing I'm struggling with is the remnant Bayer pattern colors.

Here's a 400% zoom in on several problem areas.  You can see the color-fringing I'm talking about on the left, and amongst the dark letters.

Now, it's clear that the results are dependent on the settings, but I guess the one thing I want to point out is that for the ACR 7.1 beta conversion I have actually dialed-in some defringing, which is more aggressive than the out-of-box default - and I'm not sure I want to make it more aggressive.

It seems to me the "Defringe All Edges" feature better compensated for the Bayer Pattern color fringing than this new code does.  I will continue to experiment to see if I can find a better set of defaults...

Defringe:  All Edges was a good feature.  I'm sorry to see it go.

Thanks, Vit.  Yes, the Moire Reduction does work quite well on this kind of fringing.  But I really want to have Camera Raw 7 work as well as or better than its predecessor on default settings and on all edges. 

The new Defringe process is *almost* as good.  And turning it up higher isn't really an option, as you have shown with your post on CA correction.

Since posting the above I have tweaked the defaults I have set, and the difference between 6.7 (with Defringe All Edges) and 7.1 with my defaults is now very small, and with some improvements in other characteristics, so I think I'm pretty happy.

-Noel

Yes.  I do use that feature sometimes, but as a default it has some downsides.  My philosophy about noise reduction is to use it sparingly to not at all, and only to reduce visible noise below the distraction threshold.

-Noel

Hi Dorin,

There is some debayering color pattern in each conversion, but the Defringe:  All Edges function makes it less in the CS4 and CS5 conversions.  That's not a default setting.  Without that setting, there's slightly more such color inaccuracy around edges in CS6 conversions.

Yes, I double checked my settings:

-Noel

All the problems still appear to exist in 7.1.

The features removed without acceptable substitutes are still missing, with no option to select them.

Adobe:  You need to heed the feedback from folks kind enough to test your beta software and actually fix what you’ve done wrong before actually releasing it.

-Noel

Clearly the folks giving feedback didn't look closely enough.
