Thanks, billyphoto, for your excellent detailing of this "There was an unknown error while writing metadata to this photo", which is an issue I, too, am having. I am not, however, using SEP2, but Nik Color Efex Pro 4. And the ! metadata error seems to only show after a roundtrip edit in CEFP4 from Lightroom (3.6 -- on my Mac 10.7.2), but only after assigning that edited photo to a collection. Before adding to the collection, no ! metadata error. But after adding to a collection, the ! metadata error appears in both the collection image and in the Library's film strip. Like you, when if I choose "Import Settings from Disk", it changes my file back to the state it was preceding the CEFP4 edits and the ! goes away -- but then I've lost all those CEPF4 edits. I've learned, therefore, to just ignore the ! metadata error (without any apparent subsequent problems), at least for now.

P.S. Reverting to LR 3.5 fixes it for me as well.  Lightroom 3.6 introduces some bug.

So I wonder is this a NIK issue or Adobe issue? What's involved with reverting to LR 3.5? Will Lose all my presets and plugins?

Thanks

Good to know. Thanks.

How do I revert to 3.5? Do I uninstall 3.6 first or install on top of?

Hi,

I'm wondering whether this is another incarnation of the (in)famous keywording bug that we had in SEP before the latest update. It had been revealed by a new version of LR but the "culprit" was actually SEP which was not handling metadata correctly. It seems that we'll again get into another "their bug - not mine" exchange series between Adobe and Nik Software.

My two cents...

I have discovered a workaround which is working fine (... for me with two mouseclicks):

Immediately after the SEP Processing I run a predefined export to replace the SEP-TIFF with an exported duplicate TIFF. After that it is possible to write LR changes to the file with no problems.

This is the solution I was about to test. Thanks for confirming that it works.

MfG.

Are you running LR 3.6 ? Under Windows, I don't have the "Add to stack" option.

Hi

I am not able to login into the forum ... don’t know why.

I am on Windows 7 ... LR 3.6 ... SEP 2.003 ... and it works.

Hi,

I am on Windows 7 ... LR 3.6 ... SEP 2.003 ... and it works.

I'm using XP Pro and SEP 2.003 and there's no way to get this working. When I try to export a TIF file with the same name as the TIF file created for SEP2, LR immediately stops the export because "The destination for photo xxxxx.tif would replace the existing photo." . If I export and rename, the new TIF file is created but there's no way to save the metadata. The "Exclaim" icon is still there and will not disappear after trying to save new metadata.

Although the progress bar in the upper left corner of the LR window seems to indicate that the metadata are saved, they are not. I checked this with ExiftoolGUI.

If the metadata are actually saved in your case, it would be interesting that you describe accurately each step of your procedure. There must be something that you are doing that I am missing.

Thanks in advance.

OK, let me try to describe the process step by step.

Basis is a *.DNG master picture.

The option in the catalog settings “Automatically write changes into XMP” is

checked (activ)

I hand over this DNG to SEP Pro 2.003 and made some changes in SEP and than

come back to LR. A TIFF was created.

And immediately after that I run the export to the same location and the

same filename (without any changes in LR at this point in time)

and get the result without any warning regarding metadata conflicts. I can

make now some changes in LR (more stars, Color mark, crop the picture etc.).

The metadata are saved in the file w/o any conflict.

I am able to read and write metadata w/o any errors or warnings.

Hope this helps.

regards, Hans Joerg

P.S. Somtime I have recognized that I have got some metadata warnings when I

export JPG files with the same method (but w/o any involvement of SEP - just

pure LR). But this warnings can be solved by read or write metadata again.

As I mentioned in my post above I believe that there are some (timing)

issues with the communication LR/W7

I have made some tests with LR 4 Beta and SEP 2.003: Same metadata issue as with LR 3.6 and SEP 2.003

The main difference with my settings is that I have disabled “Automatically write changes into XMP” for performance reasons. I will check this.

I re-enabled this option but this didn't change anything. No way to save the metadata in the TIF file. I'm not sure that it is a Lightroom problem, though. The keywording bug in SEP 2 (which was rather similar : metadata messing in the TIF file) has been fixed by Nik Software, not by Adobe.

Just tried Adobe. Let's see: http://gsfn.us/t/2l7gf

Man, considering I did not live through the "keywording mess" bug and that was my first post against your 375+ I would say I am probably being naive :-) Let's just hope they are gonna say something. I tried both sides. Happy 2012 !

Oh boy... any quick tip on how to downgrade ? Never did on this direction...

I had the same problem with NIK HDR EFX and 3.6 but NIK just put out an update this past week and the problem seemst o have gone away...

Just received this from NIK:

Thank you for contacting Nik Software.  As our engineers are looking into exactly what is causing this issue, the quickest fix is to reinstall Lightroom 3.5.  It seems to be only Lightroom 3.6 that receives this error, and so far reinstalling version 3.5 is the only consistent fix.  You should be able to reinstall 3.5 without uninstalling 3.6 first.

having the same problem I figured a way around it:

- edit your image (as a copy) in SEP2

- process/ close SEP2

- stripp all the metadata from the created file with the help of exiftool (you can also use exiftoolgui)

- copy all the metadata from the original file to the edited file again with the help of exiftoolgui

- read the metadata with LR

- you will in most cases a strange looking image with wrong colors and contrast - this can be corrected by resetting the image in development module

- now you can do all the edits / taggings /... without furteher problems

Hi,

FYI

Received yesterday from the Nik Software support:

I wanted to follow up with you regarding the metadata issue you are experiencing in Lightroom and our products. We have isolated the issue and should be releasing a patch soon for all of our affected software. The recent update to Color Efex Pro 4, ver 4.002, resolves this issue. Thank you for your patience.

....

The Silver Efex Pro 2 update should be released shortly.
