Hi,
there are differences from same nef+xmp developed into LR 4.1 and then opened into CS6 (Camera Raw 7) ?? Look at this shot...



what is the right interpretation?
Into 4.1 there's more noise, into CS6/cr7 isnt visible.
Best regards.

The attached image is too small to see any differences or even the values of the sliders.

My default browser is showing the same sized image as the embedded preview. I tried a different browser and it was full-resolution like it should have been.

I see the white-specs, now.

Save your ACR 7.0 plug-in, somewhere, and update to ACR 7.1 and see if the toning is more consistent between LR and PS, then. Because it was part of the big new CS6 release, ACR 7.0 was finalized in February (check the date of the plug-in file, itself), so perhaps there were some toning bugs *fixed* in LR 4.1/ACR7.1 and that is the difference, or maybe another bug was introduced. Because your blacks are pushed higher, I wouldn't call it a bug unless LR 4.1 and ACR 7.1 also show a difference, and even then, it could be a video-driver issue. Exporting/Saving out of each and comparing would help isolate that variable.

If you find that LR 4.1 and ACR 7.1 are different, still, then share the NEF/XMP or DNG with the settings updated into it, via dropbox.com or yousendit.com and post the public link for others to try. This would help determine if it is a LR-hardware interaction that others might not see.

Thanks, asap I'll test it with acr 7.1 and then will share nef/xmp.
From 7/7.1 so much differences? I dont know but could be possible.

Stay in touch, thanks.

The PV2012 toning model you are using with the images is new for this version of PS and LR and at least one bug did involve differences in how ACR and LR were handling some of the new PV2012 toning so it would make sense that things changed in the three months between when ACR 7.0 came out and LR 4.1 was released.

Steve, its ok with latest 7.1, same results as LR4.1 (......I had preferred the version with the black instead of noise).
Thanks!

It seems that there are really some significant changes from LR 4.0 (ACR 7.0) to LR 4.1 final (ACR 7.1).

It seems that 4.1/7.1 renders some images brighter than 4.0/7.0 when a lot of clarity is used, and e.g. a little bit darker when no clarity is used, but highlights are reduced and shadows increased. This may vary from picture to picture, but it seems to be most prominent for pictures with large dark areas (such as moon pictures).

Here is an example: This is a 100% crop from a 10MP image (Canon 40D raw), with Adobe defaults except black+white treatment, exposure -0.50 and clarity +50 - same settings used for export in LR 4.0 and 4.1 final (click to see the animation):



Note how the noise is more pronounced in the 4.1 version, just like in the original post (however, not as strongly).

Edit: Here is another example showing the reverse effect: Same picture, but with exposure -0.20, highlights -20, shadows +25 and clarity *zero*:



Remark: When all-zero Adobe defaults are used, 4.0 and 4.1 produce an identical export result.

P.S. Just to clarify: I did not test using Photoshops ACR, only Lightroom itself was used.

Adobe did adjust the PV2012 Toning to correct a discrepancy between ACR 7 and LR 4 so as difference is not unexpected.

Was the ACR7 converson in your first post really LR 4.0 or have you not re-tested with ACR 7.1, yet?

Because of when the ACR7and LR4 products were released, the raw engine code for each had different cut-off dates, so one might have bugs when the other doesn't. This usually happens when a completely new suite and a completely new LR version are released some months apart. While the initial releases can be out-of-sync, the subsequent minor updates for cameras and bugs are usually released at the same time and should do things the same.

If you find that LR 4.1 and ACR 7.1 are producing different results for the same settings, then that would be something to report as an issue to be either explained or fixed.

I think he is saying that 4.1 and 7.1 give the same results.
Back to the issue reported from the OP I believe he is using very extreme settings that are not likely to happen too often and, in any case, I found that this very minor change has been for the better..

I also disagree with his conclusion that we have allegedly traded black for noise (he means "less" black, but this is only a language difficulty I suppose). The 2 images show a clear difference in sharpening and contrast.
My advice to the OP: don't spend too much time looking for those minor differences that are totally immaterial to the final quality. Instead...go out and take pictures...and be happy!

Extreme settings used for moon's pictures, Im taking pictures of this kind by some years, developed by LR3 and then LR4. With lr4.1 I've seen a lot of differencies from v4 to 4.1 so, finally I know why :)

Did you notice this fix in 4.1 release notes?
Clarity adds grey tinting to 100% white tones.


The clarity certainly has been modified, first in RC2 then in 4.1. I think that is the reason we see different renderings with very strong adjustments on contrasty images like moons and suns.
