P: Photos incorrectly considered as "changed" by republishing and smart collections

Report · Sep 04, 2016

[Update from John R. Ellis:

At least some instances of this bug are caused by the new develop settings added by CC 2015.6 for the Guided Upright tool (2015.6 was released 6/8/2016). When 2015.6 or later first renders a photo at 1:1 zoom that had been imported by 2015.5 or earlier, it adds those develop settings before rendering. Then it compares those develop settings with the old, notices they are different, and incorrectly marks the photo to be republished.

Here's how to work around this instance of the problem: https://feedback.photoshop.com/photoshop_family/topics/modified-to-republish-problem?topic-reply-lis...

See here for a detailed recipe to reproduce the bug, along with an analysis of the problem and suggested fix: https://feedback.photoshop.com/photoshop_family/topics/modified-to-republish-problem?topic-reply-lis... ]
-----------------------------------------------------------------------------------------------------------------

Sometime photos in my published collections began to randomly mark themselves as modified to republish. Photos I haven't touched in years, in galleries I haven't recently changed, all of a sudden appear under 'Modified Photos to Re-Publish.' If I even scroll through a collection, dozens of the images begin to jump up to 'Modified Photos'. I can select the photos and send them back to 'Published' with 'Mark as Up-to-Date,' but then more immediately jump up to Modified.

Yeah! It's not obvious what LR decides is a "Change". Obviously things like star ratings, titles, captions, exportable keywords or anything you do in the develop module cause it to go to Modified, but other more subtle activities can also do it. I don't know what else causes it to "jump" as you say, but it could be something as mundane as just opening the image in the Develop module or syncing with a mobile device or even publishing in an entirely different publish service. I'm not saying that I know any of these 'changes' cause it to jump, but something does and it's not always clear what it was. You may want to check what other plugin's you have active as sometimes work they do in the background could trigger LR to mark the image as having been changed. One thing the gets me a lot is if I move a KW from one parent to another or fix a spelling error on a KW or any of its parents, or add/remove a synonym.

I've also seen situations where the act of publishing an images caused it to be marked as changed and have it pop right back to modified. I think the issue here was the inability to turn off the cross transfer of comments. So you have an image and publish it which sends it to the service. Then LR asks the service for comments and the service replies with "none" or returns a new comment which in turn marks the image as modified when the comment is added to the metadata. Circular logic.

It doesn't 100% solve the problem, but some 3rd party Publish Service plugin's, such as those from jfriedl, have a panel in Publish Service set up where you can check off the things you want to be considered a "Change" or un-check them so they won't be considered a change. For example in his Facebook Publish Service plug-in you can check or un-check any of: caption, copyright, creator info, GPS location, instructions, job identifier, exportable Keywords, label, provider, rating, source, title, image date. when I switched from LR's Facebook plug in to JFriedl's and unchecked all but caption, Keywords and Title it reduced the problem you describe by over 90%.

This is at least the third post on this topic in the last couple of months. It clearly started with the 6.6.1 update. I'm only publishing to my HDD and pretty sure my hard drive / OS is not updating image metadata. Does anyone from Adobe read these forums?

Report · Sep 15, 2016

I'm having the same problem-

I'll go to a publish collection and while I'm looking at the published photos, they will suddenly appear as Modified Photos to Republish without any input from me. This can happen one at a time or all at once. I can mark them as Up to Date and clear them from republish status and then more will appear as Modified Photos to Republish!

I am also having this issue. I created a series of new Smart Collections that simply write out JPEGs to folders on my hard drive. I "Publish" the Smart Collection using the Publish button, and randomly, after a photo is really published, it immediately appears in the "Modified Photos to Re-Publish" section. This is a huge inconvenience and an unacceptable bug that will kill many peoples' workflow.

I have experienced this for several months now. I can reproduce the error at will.

If I browse my Flickr-collection, triggering preview-building, it WILL randomly kick photos into modified-to-re-publish. My collection contains nearly 3185 photos since 2007, therefore most of have had previews aged out. More to the point, I recently zapped all my previews (70Gb) due to disk swap. The random re-publish flagging then kicked into over-drive.

It only happens if I browse the Flickr collection (all markeed as up-to-date) in grid view. No selection necessary, just scrolling into a region of non-preview material will do the trick. Every thumbnail render does not trigger the flagging, only some. That is to say, it is not because previews do not exist, it is because they don't exist AND a sprinkling of voodoo.

Update: If I select all Flickr collection photos, then generate previews, the behavior occurs. For as long as preview build job takes to complete, i.e. in the background and without user interaction.

In summary
- When previews are rendered...
- ...and some unknown condition is met (only some, not all, photos)...
- ... metadata change occurs, sufficient to nudge the SmartCollection logic

Auto-XMP is disabled. Catalog is consistency-checked on a regular basis.

Robert

Last night, I came home from work, edited 3 photos, and then tried to create a smart collection where the criteria was "Edit Date" is Today. Much to my surprise, 91 photos were in the smart collection. Now I suppose it is remotely possible that I accidentally selected and edited these 91 non-contiguous files, but I consider this extremely unlikely. Also, it is remotely possible that Auto Sync was on when I edited these three photos, but that would show up in the history of all of these 91 photos, and there is nothing in history to indicate Auto Sync was on, or that new edits had happened since these were published via a Publish Service that left it's date-time stamp in the history.

This morning, I woke up, launched Lightroom, and created the smart collection anew. Since I had not used Lightroom overnight (I was sleeping), and Lightroom was closed overnight, I assumed that the smart collection with criterion "Edit Date" is Today would produce zero photos (as no photos had been edited Today, a few had been edited yesterday). The same 91 photos appeared in the Smart Collection.

Possible causes:

I was sleepwalking overnight and re-edited the same 91 photos, but don't remember doing it

I think it's a bug.

See Paige's original topic for an extended discussion of his symptoms: Lightroom: Photos spuriously marked as "edited" , which are very similar to the symptoms reported in this topic.

Report · Oct 03, 2016

I have been experiencing the same problem for years with my Publish to Hard Drive folders. I have over a dozen smart folders that only include photos that meet certain criteria: the color of the photo must be Green (this indicates that its editing is final) and the capture date must be in a certain range (a particular calendar year). This publishes all my final photos for each year into separate folders. I very rarely edit a photo i took years ago, but if i do i go to the smart folder to re-publish the photo. Usually i find that other photos are in the "modified" category, too, and it's always baffled me but i've never worried about it too much because there were only a few thousand photos in each folder and typically only a few dozen mysteriously marked "modified" photos.

However, i recently changed my setup so i now have one smart folder that publishes ALL of my "green" photos (30K+) to the hard drive on another PC on my network. Now the problem is magnified and significant because the "modified" set of pictures is often thousands. That means when i want to publish any of my new pictures (or ones i've re-edited) I have to publish literally thousands of pictures. This takes a long time and consumes a lot of CPU, memory, and network bandwidth.

I found a post in an Adobe LR forum in which a user thought that unchecking "remove person info" would fix this problem but it has not worked for me.

i'm happy to provide more details if it would help.

Report · Oct 03, 2016

I have the same problem. After publishing a smart-collection the number of photos for republish is growing up continuous.
Usually it affects photos which are visible, when I scroll in film-strip or published photos.
It seems as if LR generate new thumbnails or previews.
That's very angry!

Report · Oct 26, 2016

The same thing happened to me today. I am working on a batch of 150 to so photos; then suddenly 135 got marked as needing republishing. They are showing the mysterious "metadata was edited externally" flag. Now I have to update the links and proofread the whole InDesign book again.

I've checked the edit history on a sample of these and there are no edit steps on the photos since last published. I have not changed the Publish service itself. I have not changed any metadata either as far as I know (unless I hit something odd by accident). No other application has written to these files - they are placed in InDesign but I am not using any other editing application.

I am having this problem only in the last couple of months. Simply opening an image in the Library module to view it causes it to be marked for republishing.

Good news. As of Lightroom CC 2015.7 (OSX Sierra 10.12.1), the problem appears completely cured.

I have not observed a single "accidental" update flag for over a month. Additionally, reproducing the bug (in 2015.6/6.1 by browsing collection, a preview gen. triggers issue), no longer does anythign it should not. Excellent!

I don't suspect MacOS update (10.11 -> 10.12) had anything to do with it though, with both being applied on release (within days) I can not say for certain.

Same here: Windows 10 / Lr 6.7:
- Double click photo to get 1:1 Zoom and the photo becomes "Modified to Re-Publish"
- re-publish photo
- double-click the photo again: this time it stays "Published"

It seems that if you have a preview in cache, nothing happens, but if the preview has to be rendered, it will trigger the state change.

If this reliably happens, it would be great to determine if particular metadata fields indicate the proximate cause of the problem. Adobe hasn't acknowledged any interest in tracking this down yet, but if we can narrow the cause, it's more likely they might fix the bug.

1. Select a file that hasn't yet been zoomed.

2. Do Metadata > Save Metadata To File.

3. In Finder/File Explorer, save away a "before" copy of the file (and it's .xmp sidecar, if it's a raw).

4. Double-click to 1:1 Zoom to trigger the problem.

5. Do Metadata > Save Metadata To File.

6. In Finder/File Explorer, save away an "after" copy of the file (and it's .xmp sidecar).

7. Upload the before and after copies to Dropbox (or similar) and post the sharing link here.

If I get it right, Lr is filing a metadata change

      stEvt:changed="/metadata"/>

which will definitely trigger the re-publish event.

Edit: sorry for the bad layout of the code blocks, I'm adding a screenshot from WinMerge showing the differences, hope this renders better.

If you did Metadata > Save Metadata To File as described in my steps above, that would account for the changes -- LR will always update those fields whenever it updates the metadata in the file.

Can you repeat this again, but this time, first set the option Catalog Settings > Metadata > Automatically Write Changes To XMP. Then repeat the steps but omit Save Metadata To File, instead just waiting 60 seconds before grabbing a copy of the file after zooming (to give LR time to write the metadata changes back if they have changed).

Also, it looks like these are JPEGs. Can you upload the before and after JPEGs to Dropbox or similar, so I can put them under the microscope? There are many more fields than those recorded in XMP.

So the steps would be:

1. Set the option Catalog Settings > Metadata > Automatically Write Changes To XMP.

2. Select a file that hasn't yet been zoomed.

4. In Finder/File Explorer, save away a "before" copy of the file.

5. Double-click to 1:1 Zoom to trigger the problem.

6. Wait 60 seconds, then in Finder/File Explorer, save away an "after" copy of the file (and it's .xmp sidecar).

7. Upload the before and after copies to Dropbox (or similar) and post the sharing link here.

John,

I'll do that in a minute, but here is another interesting observation:

When I re-publish the photo and zoom-in again (which now does not trigger the re-publish event), Lr again files an new <xmpMM:History> of the same type.

So, it's may be not the

stEvt:changed="/metadata"

but the

stEvt:softwareAgent="Adobe Photoshop Lightroom 6.7 (Windows)"

which did change from Lr 6.5 to Lr 6.7 between the two previous events.

"Automatically Write Changes To XMP." was already set:

http://messmer-online.de/2009_10_30_DSC-HX1_DSC00955-Before.JPG

Zoom-In ( photo is to re-publish), waited 60 secs, closed Lr (just to be very sure Lr did write back any changes):

http://messmer-online.de/2009_10_30_DSC-HX1_DSC00955-After.JPG

but no changes in JPG file.

So that suggests the problem is not with metadata, at least the metadata that is written back to the file.
