Lighroom 3 writing metadata to image files?

Hi,
I have been wondering why my backups (differential) weregetting larger than they should, and I noticed that some of the files (.psd and .jpg, and mayde few .tiff) were modified. Interestingly, I do not see this happening to cr2-files, that I mostly use. After trying to figure out what's going on I noticed that corresponding xmp-files were modified also. This is not the issue due to their small size, but still I had not edited images that were changed for quite a while.
Change that I see in xmp-files is rather large, and presumably related to Adobe's change in xmp-data structure. Eg.
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 5.3-c007 1.136881, 2010/06/10-18:11:35
">
<x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 4.2-c020 1.124078, Tue Sep 11 2007 23:21:40
">
In addition to the sample above, whole xmp structure is changed. So I presume that maybe LR is writing metadata chages to xmp in the background?
What I find disturbing is that when checking changed jpg files, I saw the similar data written into the jpg files also (files were created with oldish Canon 20D, and not edited for quite a while). These are examples from changed jpg-files (not the same from which the abone xmp-data change was taken, but similar change is visible in the corresponding XMP):
Also jpg-file from offset 0x04 was changed from "50 60" to "51 18". Also offset 0x10 was changed (16 bits).
I have Lightroom configuration option "Include develope settings in Metadata Inside JPEG, TIFF and PSD Files" not selected. The option "Automatically write changes to XMP" is selected. To my understanding neither of these should not have impact to the issue. Is there something else I should check?
Change is made most likely by Lightroom 3.5 version, and has not occurred with previous versions. I have not notices this happening with 3.6, but I have been using it only few weeks. Is this known issue with previous version 3.5, or am I missing something obvious?
System running is Windows 7 pro 64bit. I have not have any issues with LR lately, except crashes that I white about a week ago.
Any advice on what's going on?

So I was missing something. Thank you Hal.
I had not realised that XMP goes inside of actual image files with those file types. Obviously my new backup routine spotted that, as I was on backuping only modified/new files.
I would much prefer that also with above mentioned file types XMP-data would be stored in sidecar files instead of modifying the original file. To support this there are two arguments that I think are valid:
1) modification of the file is always risky (and spesifically, with image originals I prefer to avoid that),
2) modification leads to the fact that "smarter" backup strategies relying on "full backup" supported with differential or incremental backups lead to unnecessary long backuptimes and media consumption.
That said, I prefer to have XMP-data also outside of the catalog so that other tools can also utilise it (further, in addition to the catalog with sidecars I have sort of failover approach, and some of you may now say "belt and syspenders" after mentioning backups...).
Is there a way to have all file types to utilise sidecars rather that modifying original file?

Writing metadata to media-file

Hello everybody,
I'm developing an application for viewing/editing metadata of media files (mainly MP3). Therefore I'm using JavaFX 2.2.
Viewing works like a charm, but I'm currently stuck at the editing part.
I've tried media.getmetadata().put("string", object) but this throws only an UnsupportedOperationException.
Am I doing anything wrong? Or is there any other way writing metadata to media files without using external libraries?
Thank you in advance

is there any other way writing metadata to media files without using external libraries? No.
JavaFX media libraries are currently only support playback and not editing (even for metadata).

Error writing metadata to any file except jpegs

Hi all,
A coworker and I have been assigned the job of keywording all the photos in our database. We aren't photographers and are only messing with the keyword metadata on the photos.
But we've been having a consistent problem with Bridge CS4. When I attempt to add keywords to any file format except jpeg, it gives me an error message "Error writing metadata to " and the filename. Then to make matters even worse, Bridge continues trying to add the metadata to the same images over and over again until I do a forced shutdown.
We're running Bridge on a network with exported cache. The only thing I have found as a possible solution is a permissions setting problem, but I can't find any way to check on that.
Any help you can offer would be great. Thanks!

I had this same problem. This was the solution for me in my CS4.
Go to Bridge
Go to Preferences
Go to Metadata
Make sure IPTC and Keywords are checked.
This will allow you to add keywords to your metadata in bridge.
Here it is not checked:

Error writing metadata to photo files

I am using CS6 and have moved to a new computer with a clean install of CS6 under Windows 8.1. In the past I had no problem using Bridge to append my personal metadata file to photos (RAW files, NEF). With the new installation I am getting the repeated message " Error writing data to...." even after trying all the " fixes" suggested by the help files.
Can anyone help me to resolve this issue?
Thanks.

I found an answer, somewhat different. I did more search and found that you need to be administrator and for Adobe to see you as administrator, for many functions to work, such as writing metadata to files or putting stars on photos to rank them. I could do neither.
THEN, I tried opening Bridge by right clicking on the icon, and opening the file as administrator (a choice). Everything worked. So, why was Adobe not seeing me as administrator. My user account was the only account on the computer and has administrator privileges.
I started doing searches on that, and stumbled, yes stumbled, on what I think is a solution to that situation.
I set up my account so that I needed a password to log in. Once I did that, Bridge worked fine. But, I still did not want that additional startup step. You can then back to change password and leave the password entries blank. Then, the computer starts up with blank passwords, zips past the welcome screen directly to the desktop, and Windows now sees me as the administrator, and so does Adobe.
Keep you fingers crossed folks, this seems to be working.

Cannot write exif and tiff metadata in image file

Hi,
I have a public XMP text file containing exif and tiff metadata: http://ns.adobe.com/exif/1.0/ and http://ns.adobe.com/tiff/1.0/.
I want to write these XMP data in an image file and it doesn't work. I don't get any exceptions, just the metadata are missing in the image file.
C#
using (var xmpFiles = new XmpFiles())
      if (!xmpFiles.OpenFile("test.jpg", handler.FileFormat, OpenFlags.OpenForUpdate))
          xmpFiles.OpenFile("test.jpg", FileFormat.Unknown, OpenFlags.OpenUsePacketScanning | OpenFlags.OpenForUpdate);
     using (var xmpCore = new XmpCore())
          xmpCore.ParseFromBuffer(xmpPublic.ToString(), ParseFlags.None);
          if (xmpFiles.CanPutXmp(xmpCore))
               xmpFiles.PutXmp(xmpCore);
     xmpFiles.CloseFile(CloseFlags.None);

Does anyone can help with that problem?
Thanks,

I found the answer by myself.
According to the last guidelines from metadata working group, exif and tiff data should not be saved as XMP data in jpeg images anylonger because jpeg natively supports exif data.
"The most recent (as of mid-2010) XMP specification describes the usage of Exif/TIFF properties within XMP itself. Both Exif ( http://ns.adobe.com/exif/1.0/) and TIFF ( http://ns.adobe.com/tiff/1.0/) namespaces have been defined so that corresponding Exif properties can be stored. This is particularly useful if Exif properties need to be stored but the file format does not support native Exif (e.g. PNG). [...]However, this document changes this earlier XMP guidance and recommends that Exif and Tiff device properties only be mapped into XMP in the case the file format does not support Exif natively."

Bridge CS3 not writing metadata to JPEG files

For the last couple of months (without my noticing until a couple days ago) all JPEG files that I have edited using Bridge CS3 (on Windows XP) do not have the metadata built into the file. Here are the symptoms: use "File Info" to edit the metadata for a JPEG file (i.e. add a title, description, copyright info, etc.), all appears normal, but if you do any of the following, the metadata you entered disappears:
- duplicate (the metadata does not exist in the duplicate file)
- move or copy to another folder
- open in Photoshop or any other software that can read metadata (File Info shows none of the metadata you entered)
- rebuild the cache for the folder
Strangely, the metadata still appears with the file when you look at it in Bridge as long as you don't do any of the above.
This is really awful as I've put a lot of time into entering this metadata for hundreds of files. Older files (pre-Nov 08) don't have this problem and the metadata is "sticky" and doesn't get deleted. So, somehow my Bridge CS3 got corrupted along the way.
Has anyone experienced this and more importantly -- do you have a solution? I've tried reseting all Bridge settings (but that of course purged the cache and deleted all my metadata.)

Hey,
There are various date/time fields shown in properties panel in Organizer. The dates mentioned in general section are read from OS whereas the dates in EXIF field are read from image's EXIF data. In EXIF data there are three date/time fields-
1. Date time- This date/time info shows date modified of EXIF properties. So when you are writing a tag into imags's IPTC, you are doing some change in EXIF data. Hence this date should change to date when you are writing a tag into IPTC.
2. Date time original - Represents date time when a image was shoot.
3. Date digitized - Represents the date when the image was digitized (in digital camers there is hardly some delay between an image is shoot and it is digitized. So this field is always same as date original).
So, in your scenario, Date time in EXIF should change whenever you are writing any tag into its IPTC.
Please let me know if you need more info on it.

Is there a way to extract an image file metadata?

I know this isn't specific to PS but hope there's an answer here.
I'm transcribing some of the metadata from image files to build a simple catalog. Included are things like dimensions, resolution, and photo date. Is there a way to extract this data other than manually?
Thanks
Tom

Can no longer write metadata to Raw files

My team an d I are working in Photoshop CS5, we write metadata to jpegs and Raw files- saving to Raw database not as sidecar .xmp files. We are no longer able to save the metadata to Raw files. There is no error message, the data writes like normal and the user who writes the metadata can see it but when you open in another computer the metadata fields are empty, however the jpegs do have the new metadata. Was there a setting change at some point? This has been going on for a couple months and I cannot find an answer anywhere. Again, we batch write to RAW+Jpeg, the jpeg files save the metadata but the Raw files look like the data saved but is not visible on any computer other thant he one that added the new metadata. This is occurring on multiple computers, both Mac and PC.

I understand the process you are describing, In the past I have been able to embed metadata to a Raw file, move it to a server, pick that file up on another computer and see the metadata without need of the .xmp sidecar. Is the ability to embed no longer supported by Photoshop? Since this issue began we have taken to doing all our metadata editing in PhotoMechanic, which embeds without creating a sidecar. If Photoshop is pushing people to create sidecar .xmp files only for writing metadata to Raw files I will probabaly move fully to PhotoMechanic because using sidecars has proven tricky in the past with how our files get moved around.
If using Adobe Camera Raw on camera raw file you either have an XMP sidecar file created or the data is stored in a database. Which happens it is your option in Edit/camera raw. If you use ACR and edit a jpeg it does not create a distinct XMP file but it is also not directly written to the image either. One can still delete the edits in Bridge with Edit/develp settings.
If you use a DNG the metadata is written to the image. Not sure what process Photo Mechanic uses.
It appears to be a permission problem as other than CS6 Bridge is now 64 bit and has a new cache method there are no changes in how it handles metadata.

Lightroom 5 can't write metadata to DNG files

I have converted a large number of Canon and Nikon raw files to DNG using Adobe DNG Converter (version 8.2.0.94).
Using Lightroom 5.2 I wanted to change metadata in these master DNG files. I import the files into a catalog, select all, modify the metadata, then invoke the Metadata->Save Metadata to Files... For many (but not all) of the files I get the following message:
"Could not write metadata. Unknown file formats."
The DNG files reside on a Synology NAS server. If I copy them to a local disk I do not get the above error. But I would like to make metadata changes to the files on the NAS.
I do not have problems importing or viewing DNG files from the NAS. Why does LR 5 have problems writing DNG metadata to the NAS? How can I fix this?

Thanks for replying.
The problem is definitely not one of permissions. I am accessing the NAS from an admin account with full permissions to read/write the files and directories.
I'm inclined to believe it's the second cause you propose -- network protocol causing data corruption.
It seems to be specific to writing metadata to large files such as DNG or TIFF. I don't get errors writing to JPEG. And it is inconsistent -- sometimes retrying fixes it. And, oddly, sometimes I even get the error "photos have read-only access" when it's clear the permissions are OK.
On the other hand I have had no problems copying thousands of DNGs to/from the NAS -- no errors and no corruption. So the issue seems to be an interaction between the NAS and LR when LR is updating the metadata on an existing file and the file is large.

Error writing metadata to file

I am getting constant error messages from Bridge CS4 when trying to add keywords to my images "Error Writing Metadata to file "XXXX". It's very annoying and destroying my workflow. I have tried resetting original preferences, and using purge cashe. Finally I reorganized my entire folder structure which seemed to make the problem less frequent.
The circumstance that makes this error pop up most frequently is when I add keywords to a handful of files that already have another keyword assigned. Quitting the folder and then re-entering it solves the problem for the photos with the current error, but then 20 or so photos later I get the error message again.
Any Fixes?

A new suspicion was that the read/write data might be different for the images files themselves than it was for the folder holding them. So I applied the read/write permission to the image files themselves. No luck though. Still getting "Error writing metadata to file xxxx" Errors. Would love to be spending all this time editing photos instead of chasing down bugs. Brand new MacBook Pro and I'm spending more time trying to fix errors than using the software. ::sigh::

Faillure writing metadata to some DNG files

I'm having a problem writing metadata to some dng files using Lightroom 2.6.1. When I try to apply a metadata template to a batch of files most of them get changes but a few don't. This only effects DNG files so far JPEG and TIFF seem to be OK. I have tried running the problem files through DNG converter and the new files have the same problem. Lightroom won't write to them.
I can change the metadata of these files from Bridge. The changes then appear properly in Lightroom. Afterwards I can change the metadata again from Lightroom.
I'm working on a MacBook Pro (Late 2008) and running OS 10.6.2.

I created a preset to export to same folder as original, same format as original, and stack with (above) original. I used this on the seven files, and it has solved the problem without losing any metadata.
The jpegs had at some point been processed by Photoshop Elements as they were imported/edited using that application in 2010 but the metadata problem didn't show up until recently when I was making some adjustments in Lightroom. I somehow think this may be related to the GPS tag though I don't have sufficient evidence.
The DNG file was strange in that it was straight the camera with no Lightroom adjustments, although I did add GPS info in the Map module. Anway it is now fixed as well as the jpegs.
With this preset it would be possible quickly to fix a large number of image files. Just create a Smart Collection to display the problem files and run the preset on them all in one go. The only things that I am aware of that you would need to look out for are (1) if they are in a collection other than a smart collection, or have been published to a service like Flickr or to the Hard Disk the link will be broken, and (2) If you like to sort photos by date/time added, they will be out of the sequence (capture time is fine).
When you are satisfied that this has worked OK then you can delete the images from the "Metadata Not Up To Date" smart collection. Select all, go to all photos, they should remain selected and press Delete. You could do a thousand in one go if you have the nerve for it
Hope this helps.

Errors when writing metadata to files on Windows Server

Good day!
I have an iMac running OSX 10.9 (Maverick) and Lightroom 5.2.
My catalog is on the local iMac drive, and the images are on SMB shared drive (handled by Windows 2012 server).
I decided to do the final layout of my album using InDesign, and for that I needed to access to images using Bridge. So selected all the images (the rated once...) and issue a Metadata/Save command.
The system came back with errors on many of the files (such as Photos are read only, and unknown errors).
Retrying to save the metadata on image that was flagged with an error usually (but not always) worked.
I tried to select save the metadata for few (6) images in a time, many times it was ok, but sometimes, one or two of them failed (and retrying again usually solved the problem).
It looks to me like a timing related issue.
Any ideas?
(After spending about an hour on this, I have exported the images to my local drive...). In general I don't have similar problems with other apps.
Any ideas?
Yuval

I Yuval
I'm experiencing more or less the same behavior (see Read-only error when writing metadata to file over network (Synology DS1315+ using AFP) ). For me however, the problem is more pronounced if I use the AFP protocol and is better (I think as you described) if I use SMB (all done on a Synology DS1315+). With SMB it most often works but in very rare cases I also get the "read only" message!
Do you have solution to this? Or are you stuck as I am?
Cheers, Chris

Writing specialized metadata to image using Javascript...

I'm working on a project where we are dumping metadata from a database into a text file and then writing it to images using javascript. As long as I use the fields listed in the Javascript reference manual, it works perfectly.
However, the client has asked me to write specialized metadata. I created a panel for them to add in the extra fields. Is there a way to get Javascript to write the extra fields? (Is there a way to extend the DocumentInfo class in Javascript? Me thinks not...but I thought I'd ask.)
Thanks,
Laura

I very interested in this as well... Found an answer yet? Seem silly to me that do don't have access to all of your tags...

Writing metadata to file iphoto 11

I came across a script (by Andrew Turner, linked to from here -http://stuffforlife.blogspot.com/2009/10/face-recognition-in-adobe-photoshop.htm l) that writes the iphoto metadata to the original file, allowing the metadata to be read by other apps.

yeah, i just noticed that...!
when exiftool is working, does it write the metadata to the original raw file or the jpeg.
trying to find info on how to get round the "warning duplicate orientation tag in IFDO" error, has me scratching my head
i also have aperture 3 trial, wil this allow face keywords from iphoto to be added as metadata to the file?
cheers

Writing Image files from Applet to Servlet

How to write ImageFiles from an Applet to a Servlet?
I draw a image on a JComponent in Applet and wanted to save the image file in the server.
I am unable to write an Image Object to the Servlet as the BufferedImage class is not serialized.
I tried writing the image to the Servlet output stream and tried reading the data in the servlet and writing the data to a jpg file.
But the files is not being written as proper jpeg file.
Any help would be great.
Thanks,
Sridhar.

I get the following exception below when i try to write a Serialized object from an applet to the servlet.
I copied the serialized class jar file to the tomcat webserver lib folder.
The serialized class has a BufferedImage object.
Serialized Class Code
public class SerializedImage implements Serializable{
     private BufferedImage im = null;
     public SerializedImage() {
          super();
     public BufferedImage getSerializedObject() {
          return im;
     public void setSerializedObject((BufferedImage im) {
          this.im = im;
