Will LR write to a XMP file if...

... I set the JPEG, TIFF, PSD or DNG file to read only in Windows?
I ask because I'm not sure I want to embed this info into the file because of my backup schema. The XMP file is very small compared to the full file.
Sverre

Even without shutting of XMP writing, as Lee Jay says he will do, yuo only need to backup the Library dB file, because all the info is stored their, always. The XMP write is for portability to other Adobe apps and those others that can read them properly.
We have been told by the Adobe team back-up the dB and of course you should have a set of image copy originals backed upas a matter of course, regardless of what app you use.

Write XMP Files

I need to write xmp files. These files will I then be imported in other applications like PhaseOne's Media Pro. The rest of my application is writen in C# so I need something that works with C#. Are there any libraries to do this? Ideally, there is some xmp object that can be serialized.

The only way that I could get Lightroom to write the xmp files for these specific files was to make a change to all of them AND I had to turn on Automatically write changes to xmp files in the catalog preferences section. If this option was not set, even after making a change to the files, Lightroom would not create the xmp files.
So I finally got the program to create the xmp files, I just can't understand what's different about these 93 files that insisted on having xmp writes turned on globally before any xmp files could be created. I turned off this global setting after creating the needed files.
The whole purpose of this exercise was to change the Lense Description to a Sigma 10-20mm F4 from a Tamron lense. I found a shareware program that allowed me to select a directory of files and make a global edit to all 93 xmp files at once. I then read the XMP files back into Lightroom and everything is right with the world.
Is the option of NOT changing the lense designation within Lightroom a XMP limitation or is this a design decision of the LR engineering team? It sure would be nice to have the option to PAINT the changes (in this case lense description) from one image to the rest of the group, if one chose to do this.

Can't Write XMP Files

I'm using Windows XP and LR 1.3.1 and I can't seem to write a specific folder of files. I'm trying to create the XMP files so I can do a global edit to modify the Lense type. When I select all and then click on Save Metadata to Files, the program does not write the files for this specific folder. I have tried this on other files and I don't get the same problem. I have tried moving the specific files themselves to their own collection and trying the same process above, but I get the same result.
These are Pentax K10D files saved as PEF files.

Cannot get LR4 to read xmp files from a Nikon D4, Reads the D3S xmp files fine.

I am doing some editing work for a magazine. The lead editor had issues with adobe camera raw viewing some of my edits. The xmp files are there but for some reason they are not loading. We narrowed it down to just the Nikon D4 files. I just had her download a trial version of LR4 and we are getting the same issue. The xmp's are there in the same folder as the .nef files. Import into Lightroom, and all D4 files do not show my edits.
We are both running Lightroom 4.3, Camera Raw 7.3.

LR may or may not have up-to-date XMP files if you haven’t explicitly written them.
I have not encountered the XMP-ignored-if-timestamp-before bug but I believe it is the actual Windows/Mac file-modification timestamp, not something inside the file.
My suggestion is to write all the XMP files, again, and resend those to her. That way you’ll know their contents is current and that their timestamp will have been updated to something after the raw files timestamp. If the images are all in oen or a efw folders then the easiest way to update all their XMPs is to right-click on a folder in Library and choose Save Metadata. If the photos are more scattered but you can select them all in the Library grid view just right-click on one and choose Save Metadata to Files—make sure it says Files not File.
I assume both of you are on Windows, not one on Windows and one on a Mac?

Changes in xmp files not recognized n Lightroom

In my workflow i have setup for changes to be made to the xmp files by a program other than lightroom. In the previous version of Lightroom i had tested this, it worked fine. When i made a change to the xmp file, Lightroom recognized the change and displayed/rendered the image appropriately. Now, I am using version 2.2 and this is not happening. I see the option in th Metadat dropdown menu for "Read Metadata from File". If i click this it works. Is there an option for this to automatically happen that i am missing? If there isnt, why not? Also, I have noticed that Lightroom does not automatically write/update the xmp file if that option is enabled when using the develop module. Can anyone help me with this?

Read has never been automatic, and write is automatic but not instantly - it does it when time is available. You can use synchronize instead of read if you want to, but again, it's not automatic.

Can I save PS edits in an xmp file to be read by LR?

The reason I ask this is I have hundreds of photos that were taken on a 5D with a scratched filter, so I am treating the marks as dust bunnies and getting rid of them in the same way, using spot healing and for the scratches, whtever the feature is called where you use the spot healing brush but you 'draw lines'.
However I am one of the many who suffer appalling performance in Lightroom edits so after maybe 20 spot heals the computer slows down so much so as to be unusable. So I then send the file into PS/CS6 as the same doesn't happen there.
I quickly fix all my spots and scratches and then I appear to only have the option of saving the file as a TIF back to LR.
What I'd love to do is save the xmp file, and then have LR update the image given those xmp changes.
Is this possible or do I have to continue to have the extra TIF file?

Hmmm I can't replicate what I did now. The problem with using ACR is that the spot removal tool is just that, a spot. It doesn't allow the removal of scratches, which is the whole point of what I'm doing. If I hit 'Done' after healing a spot it does indeed write to the xmp file, but then I hvae to delete the preview and refresh in order to see the change. I could cope with that if the ACR spot removal was the same tool as in LR, where you can do scratches as well.
Oh well, I'm halfway there so should be grateful for that. Cheers.

Can I delete my *.xmp files?

I am not a photographer, but an ordinary "idiot with a camera". I have read discussions about the effect of deleting *.xmp files on "camera RAW" files and don't understand what I read.
I take my photos, save them as JPEG files, edit them using AutoSmartFix, and save them again. I then delete the original copy so that I don't fill my computer up with unnecessary files.
Will deleting the thousands of *.xmp files which I have found on my computer have any effect whatsoever on my saved ".jpg photographs, please?

No, that isn't what a raw file is. When your camera takes a photo, it's not really a picture. It's three separate groups of data, one for each of the red, blue, and green color channels. That information (the raw data) needs to be processed into something that you can recognize as an image. Jpeg is a very popular format for saving the processed data. When you take a jpeg photo with your camera, the camera's own little computer has made a lot of decisions about how to make that image look best, and it discards the additional data not needed for the final file. When you shoot raw files (.cr2, .nef, etc.) you get the raw data from the camera and then you use some kind of conversion software, like adobe's raw converter, to process the image yourself, making your own decisions about what settings look best. The advantage to shooting raw is that you can keep going back and reprocessing the file different ways if you want, and often you can pull more detail from your photos than is left in the jpg your camera creates.
However, lots of photographers don't like to mess with processing raw files, and prefer to shoot jpg. That's fine, and sounds like what you want to do. However, you would not have ANY xmp files if you were shooting only jpg. Check your camera settings--it sounds like you have the camera set to shoot both a raw file and a jpeg file at the same time. If you don't want the raw files, you can save a lot of space by not creating them in the first place. What camera do you have?

"Automatically Write Changes Into XMP" Not Working for DNG Files

Hello,
I am needing to update DNG/JPG file pairs with keywords that I add in lightroom. The following is the problem that I am encountering.
When the image consists of only a JPEG file (ie. I had my DSLR only snap a jpeg and not an associated DNG), and I add one or more keywords to the file in Lightroom, these are written / saved immediately in Lightroom and are visible immediately in the 'tags' column for that image in windows explorer. Very useful and important functionality for my workflow.
However, when the image consists of both a JPEG and a sister DNG (i.e.,snapped simultaneously by my DSLR), and I try to add keywords to these (treated at this point as a single image by lightroom) then Lightroom does not record the keywords into either of the two files and consequently no tags are visible in windows explorer. I have confirmed this apparent problem with a seperate image metadata utility software, and am hoping that it's just something simple that I am missing.
Also "Automatically Write Changes Into XMP" is selected and I have also tried manually both: "right click," "metadata," "write metadata to file;" and "right click" "update DNG preview and metadata" and the problem persists.
Hopefully someone has encountered something similar and can point me in the right direction.
Thanks in advance.

@Eric: hitting cntrl+s works but can be tedeous on large galleries. I've been doing this but it can be a pain.
@Jeannine: different topic than this thread but to answer anyways... Lightroom automatically saves all changes into your catalogue. You never need to dave your changes (here's the kicker though) as long as you do not move the original file. If you
move the file than lightroom won't know that it's the same image as the one you've edited. Once you are done editing your image you will need to "export" the image to a new file (you don't wan to overwrite the original). If you don't export than only lightroom will have your edits. Lightroom is "non-destructive" Which means that it doesn't touch your original photo. Lightroom keeps a text file containing the instructions on what you did to make the edited version. Since your changes are just text inatryxtions you have to "export" the image to get your final image in a version you can put online, print, etc. But to answer your original question, I think you prob moves the original image. If not, could you give us more info?

"Automatically Write Changes into XMP" Not Saving XMP Files

I tried finding some other discussions on this but I couldn't seem to find anything...
I recently checked the "Automatically Write Changes into XMP" setting in my "Catalog Settings". However, as I continue to add pictures to my library and make changes, I do *not* see the XMP files being written to the location of the pictures (Nikon NEF files located on my hard-drive). In fact, I can't find the XMP files anywhere. If I want to output the XMP files I have to do a Ctrl + S (Photo --> Save Metadata to File).
I did notice that when I unchecked the setting and re-checked it, *some* of the XMP files showed up. However, in my import of 24 photos, only 14 had XMP files. I had to manually "Save Metadata to File" to get the XMP sidecar files to show.
Am I doing something wrong? Is something not working right? I'm a bit confused. I assumed it would automatically export the sidecar files.
How often should it be outputting XMP sidecards? If I import a new image should the XMP sidecar file be created? Or is it created the first time I change an original picture?
I am using Adobe Lightroom 2.0 (Camera Raw 4.5) on a Mac OS X 10.5.5.
Thanks,

XMP files remain with NEF files in my folder. Camera Raw suddenly reset leaving my edits gone. Will XMP files enable me to resume with those lost edits?

XMP files remain with NEF files in my folder. Camera Raw suddenly reset leaving my edits gone. Will XMP files enable me to resume with those lost edits?

I never tried this, but I'm pretty sure that with DNG files, Lightroom will ignore xmp files, even when you instruct Lightroom to "Read Metadata from File". Lightroom expects all the metadata to be in the DNG file, not in the xmp file.
Pick flags, as far as I know, are never written to xmp file; nor are they written to DNG files.
If you're going to make this transfer procedure work, you need to do it by either (a) embedding the metadata in the DNG file and send those back and forth; or (b) use RAW and xmp and then sending the xmp files back and forth (plus I guess you have to transfer the original RAW once to your editor)

Turning on 'write xmp files' in LR 5.4 changed the modified date on my old raw and jpg files. Can i stop this?

On the advice of an article saying XMP sidecar files are a safer alternative to relying only on the catalog, I recently (June 16, 2014) turned on write XMP files. Now all my JPG and raw files have the same modified date of June 16, 2014, making it impossible to know which are the most recent files, etc.
Is it possible to change this behavior to only create these files for new images - or to stop this behavior?
I'm reverting to a backup of all my files and turning this option o ff for now.
Thx

I assume your raws are in DNG format? If xmp is in sidecar, it won't change raw file date.
Anyway, saving xmp does not change any dates in Lightroom, so you should still be able to sort by edit time or capture time...
But if you want control, you have to save manually instead of automatically.
Two things that might help:
1. Filter based on metadata status.
2. robcole.com - DNGPreviewUpdater

File Write Keyword Tag don't create a xmp file

Hi,
I use PSE 8 with WIN7 64 Ultimate.
When I used the File > Write Keyword Tag command, no xmp file is created. I saw, that the filename was renamed to xxx_edTMP-1.NEF for a short time and than the original name is show. The changedate of the file is not changed Sometimes the file is not renamed the new name is xxxx_edTMP-1.NEF.
Why?
Nils

I assume that you are trying to write tags assigned to a Raw original.
There is a bug that sometimes PSE does not write tags (or other metadata) to .xmp for Raw files. This usually depends on the type of file; this command never seems to work for .NEF files.
A workaround is to use John R Ellis's psedbtool

Maxl Script will not write to error file for data laod.

Sorry Glenn here is the new thread. I re ran without the semi colon after data 3 and the same error came up without anything being written to the error file.
I purposely removed a member from the orginal outline that is included in the data loaded but yet the error file is not written to. I tried doing the load manually but executing it in the background, error file is to be created on my local HD but it does not write it there. Checked the output and it is written to a directory located on the server. Although i think this is normal.
Could it be that it will not write to a local drive? I am going to try specifying a spot on the server to see if it runs there.
thanks
Original post below.
Hello,
I am also having this issue.
I will include my script below but will state some details before
We are on Essbase 11.1.1.3
I am running Admin Console from my client PC that connects to the server in the script and I read that in this set up the error file will not get written to. This documentation was for v 9.1.3
Here is my script (i changed some of the names)
login 'user' 'password' on server';
create application 'Money1' as 'Money2';
spool stderr on to 'errorfile';
import database 'Money1'.'Main' data
from local text data_file 'Money1_Data.txt'
using server rules_file 'Data3'
on error append to 'dataload.err';
execute calculation 'CALC ALL;' on 'Money1'.'Main';
logout;
spool off;
exit;
here is the error output i get:
code line: on error append to 'dataload.err';
Statement executed with warnings.
(3) Syntax error near ['$']
I don't see a dollar sign anywhere in my code and the error file does not get produced.
Also do error files get written too if the actins are executed in the background?
Thanks!
Alex

This works for me in a MaxL script run through essmsh.exe:
import database appname.dbname data from local text data_file "d:\\datafilename.txt" using server rules_file "rulename"
on error write to "d:\\errorfilename.err" ;Sometimes EAS (I think you are running it through that) does weird things to MaxL. I eschew MaxL in EAS as much as possible (like 100% of the time).
NB -- the datafilename and errorfilename and their drive letters are local to wherever you're running this process through the MaxL shell. I don't know how that works when you're running EAS -- are drives local to your session, local to the EAS server? Dunno. Leave EAS behind, buy TextPad (no I am not the author of that fine product) and download the MaxL syntax library, and be happy. :)

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.

XMP Files from MAC Not Reading On PC

My question is two-fold, so I apologize that this is long, but it will be best with the backstory:
I shoot Raw on a Canon 5DMIII and import my images into Lr5 on my PC as CR2 files. I am beginning to work with an editor for the post production of my images and upload my files to her via Dropbox. In effort to keep the files as small as possible (and upload/download times shorter), I export my images as DNGs. Specifically, I ensure the 'Use Lossy Compression' option is checked and the 'Embed Original Raw File' is unchecked. I then resize the image to 2000 pixels on the Long Edge and the overall file is under 1MB.
She then imports the DNG files into her iMac for editing also in Lr5. Prior to my exporting, I will edit a few images as sneak peeks for my clients, flag them as a 'pick' and code them as 'red'. When she imports my DNGs, she can see the 'red', but she cannot see the flagged images. Fine, this is something I can live without. She does her editing, also flagging them as a pick and coding them red. She then exports as the original file.
She then uses ExifTool, opens the terminal application and write in: "exiftool -xmp -b -w xmp -r", drags in the DNG files and exports the XMPs. She then sends the XMP files back to me, I place them into my folder with my original RAW files, tell my PC to 'replace' the XMP files that are already in the folder. Then in Lr5, I highlight all my files and select 'Read Metadata From File'.
Now, initially, nothing happens. I am unable to see any images flagged or coded red. However, I do see the 'attention' icon (I'm sure that is not the right name for it) on the upper right corner of the images she has edited when in the library module. If I click on it, it tells me that the MetaData has conflicting information and do I want the file or catalog to be primary. I click on the 'file' option and only then do I see her edits, including the 'red' coding (but not flagged as 'pick').
Part 1 Questions: Why when I am instructing it to 'Read the MetaData From File' is it not automatically picking up her edits? Am I doing something incorrectly when I put the XMPs back in the original folder with the RAW images and have the XMPs replace the originals? Is it normal for the 'pick' flags to not transfer?
Part 2 Questions: When she edits my images, she creates a virtual copy and creates one color and one b+w of each image for my clients. As such, she sends me back two XMP files for one image. How do I get these 2nd XMPs to map to the virtual copy within my library, as I am only creating the virtual copy of an image once I know it is one she selected for the final gallery. If I create a virtual copy of an image she edited after-the-fact, the b+w XMP cannot locate it.
Any guidance is appreciated! Thank you!

I never tried this, but I'm pretty sure that with DNG files, Lightroom will ignore xmp files, even when you instruct Lightroom to "Read Metadata from File". Lightroom expects all the metadata to be in the DNG file, not in the xmp file.

Will LR write to a XMP file if...
