Hidden metadata in jpegs

Is there a version of photoshop that can help me see the hidden metadata (original time/date made) from a jpeg sent to my iphone via a text message? The time/date I transfer the jpegs from text to my phone ends up being the time/date shown. The EXIF is most likely still with the file but I can't see it, but I would like to see if any version of photoshop can expose this hidden data.

Hidden metadata ... ?

Hi,
if I search for images (JPEG) with a certain string in "All metadata" I get photos as result that do not contain this string in one of their visible metadata tags ... Thus, I assume that there are hidden metadata, Bridge does not display.
Can I make them anyhow visible and Bridge? And can I edit/overwrite them, even if there are no standard tags?
Thank you!

The problem: In the Preferences Dialog I can only enable metadata that are known by Bridge ... e.g. the common IPTC core metadata.
But if I use the search function of Bridge searching in "All Metadata", Bridge seems to search in much more metadata, than it shows in the Metadata Panel and that is available in the Preferences.
For example, I searched for a string, that was written in the "OwnerName" of the Camera. And the "File Info..." was the only way to see and read this "Owner Name" and the way via scripting was the only way to edit this entry.
And tags are for me the metadata entries - e.g. ISO, fstop, shutterspeed, copyright, location, ... What's the correct name these things?
I don't know if there is a definition of tags, but for me a tag is an item where I have created a field, while metadata are items that the camera sets. Technically I think it is all metadata, but that is the distinction I make for my own mindset.
I believe that you can not search for something that is not checked or listed in metadata preferences. But then I could be wrong. Could not find OwnerName so unsure exactly where you are looking in File Info. If this is a field there is no way the camera would know this unless your inputted the value to the camera.
There are some fields the camera may have that Bridge does not acknowledge. There may be ways to add this, but I don't know how.

Import metadata to jpeg files

i want to import massively metadata to jpeg files.
Can you help me to import metadata such as keywords.
I have already tried with xmp toolkit of Adobe but the metadata
is not readable from file info in Adobe Photoshop CS2
What seems to be the problem ?
I 'm using windows xp

I can probably help with this.
I have a script called TagFromFilename that can apply fill in the details that can be extracted from the file path if the .wavs are stored in the layout <Album Artist>\<Album>\[D-]## <Name>[ - <Artist>].<Ext> where D is an optional leading disc number and <Artist> is an optional trailing artist (otherwise both artist and album artist are set to the grandparent folder). You just need to make sure that before you add the tracks to iTunes, that it won't rename the files. You can do this by turning off the Keep option if the files are inside the media folder, or the copy option if the tracks are located outside.
Alternatively I have another script called ExportImport which allows for almost any editable to be adjusted, as long as you can export the internal track IDs of each track and then marry them up with the data you want to import. See Batch Add Comments Tag Solution? for a previous example of how if might be done. I'll gladly go into more detail if you tell me what fields you already have and what identifying information is present.

Include Develop settings in metadata inside JPEG, TIFF, and PSD files ignored when unchecked

In the Catalog Settings under the Metadata tab, I have unchecked the option 'Include Develop settings in metadata inside JPEG, TIFF and PSD files'.
I then selected a JPEG photograph in the Library module and chose Metadata/Save Metatdata to File. I wanted to save the metadata that I had added (keywords, IPTC, rating, etc), but not the develop settings.
I then imported the jpeg back into another catalog. The metadata I had added was there as expected, but so are the develop settings. This I did not expect or want.
Have I got something wrong here? My understanding is that turning off the 'Include Develop settings in metadata inside JPEG, TIFF and PSD files' option means that develop settings are not written to the xmp area in non raw files such as jpegs.
Looks like a bug to me.
Tony

Hello all,
I have investigated this problem further and now have the answer. It is not that the option "Include Develop settings in metadata inside JPEG, TIFF, and PSD files" is ignored, but it appears that the LR catalog is not properly updated when this option is turned off.
Here are steps to test and illustrate the problem:
1. Create a new folder and place a copy of an original jpeg image (original from camera) in the new folder. Make sure you keep the original safe and only work on copies.
2. Create a new catalog in Lightroom 2.3.
3. Import the jpeg image from the new folder.
4. Add some metadata (keywords, ratings, title, caption, IPTC data, etc).
5. Make some Develop adjustments to the image.
6. Open "Catalogue Settings" from the Edit menu and check (enable) the option "Include Develop settings in metadata inside JPEG, TIFF, and PSD files". Uncheck (disable) the "Automatically write changes into XMP" option.
7. Select "Save Metadata to File".
8. Delete the jpeg image from the Library module, then re-import it.
9. Copy the original image back to the new folder, replacing the updated jpeg (once again, the jpeg image now contains no metadata from Lightroom). At this stage, Lightroom fails to recognize that the metadata in the LR catalog doesn’t match the metadata content in the jpeg file. I would have though that it should.
10. Open "Catalogue Settings" from the Edit menu and uncheck (turn off) the option "Include Develop settings in metadata inside JPEG, TIFF, and PSD files".
11. Reset the Develop settings.
12. You now need to make a change to the metadata like increase or decrease the rating (otherwise LR won’t save any metadata to the jpeg file - LR is being too smart and thinks it’s already up to date, so does nothing when you do the next step).
12. Select "Save Metadata to File".
13. Delete the jpeg image from the Library module again, then re-import it again.
14. Look at the develop settings (that you specifically did not want saved within the jpeg file in step 10).
Although the Develop settings were Reset in step 11, you have ended up with the original Develop settings from step 5. It is true that LR has not saved the reset develop settings, but it also hasn’t removed the old develop settings that are still stored in the catalog. This must be considered a bug (oversight). Note that it has also saved an Import snapshot as well.
For the more technically minded (and the LR developers if you are listening), the field "xmp" in the table "Adobe_AdditionalMetadata" is not updated (old camera raw settings and snapshot settings are left behind) when the "Include Develop settings in metadata inside JPEG, TIFF, and PSD files" option is unchecked (disabled) and it seems that this is the data that is written to the jpeg file when you select "Save Metadata to File". Note that the state of "Automatically write changes into XMP" has not effect on this process - I tried it on and off.
Hope that this might be of some help to others one day.

Editing hidden metadata in MP4?

I've been trying to organize my music collection as of late, and this task includes cleaning up the metadata for more effecient viewing on my iPod. I've come across a bit of a quandary, though, specifically regarding MP4s purchased directly through iTunes. It seems to me that there must be hidden metadata associated with these files (searches both here and on Google seem to back this theory up, as well) ... metadata that is not editable by either iTunes itself, nor the third-party program "mp3Tag."
It is proving quite problematic to my organization as a whole. Specifically, I have been removing album info from most of my collection, and these hidden tags seem to override what I have designated not only for the song in question, but every other song with removed album info when viewed on the iPod.
I have found that I can circumvent this problem by having iTunes create an MP3 version of the song, then deleting the purchased version; however, I am mildly concerned with loss of quality in converting from lossy to lossy in this way.
So... the question. Is there any way to actually edit these apparently hidden metadata values? My research into the subject has only found 8-year-old posts that direct me to long discontinued, no longer available software. If not, is there any way I might convert to MP3 without quality loss? As I understand it, you can't get lossless formats through iTunes via download.

Fortunatly, I was wise enough to make a backup of my collection before starting in on this process, so hopefully any regrets had will be limited at worst.
The tags in question, though, don't appear to be editable by any program I've yet run across, though they (the tags) clearly exist.
Below is an example of these as viewed in Notepad++, on a song that I (for the purposes of this test) stripped all metadata from in both iTunes and MP3tag.

I hadn't considered giving them a common album title, rather than just removing it outright.
*tests that*
While it does what I need it to do on the iPod, unfortunately, it would completely wreck usability on iTunes itself. Back to the drawing board.
A quick recap of my options...
- Accept the fact that I wont be able to change these tags, and have a slightly more "littered" album cover view on the iPod.
- Restore my backups and go back to a purely playlist form of organization.
- Convert all iTunes-purchased songs from M4A to MP3 to "scrub" the hidden tags, and suffer potential quality loss.
Looks to me like the only sensible answer is to go back to playlists.

What does "Include develop settings metadata inside JPEG, TIFF, and PSD files" do?

I am wondering what the option "Include develop settings metadata inside JPEG, TIFF, and PSD files" found in catalog settings/metadata does? what happens if you uncheck it?

Bob12312321 wrote:
also when this is unchecked will lightroom still save keyword changes to raw(nef) files? thank you!
Metadata ("real" metadata like keyowords nor develop adjustments) are never saved into non-DNG Raw files (like .nef, .cr2) directly. With these files, there is always a so called sidecar file (with the extension .xmp) created to hold the XMP information.
And yes, if the option is unchecked, LR will save the keywords to the XMP sidecars, when you perform "Write Metadata to File" or have the autowrite option active.

Changing pixel density metadata in JPEG

Hello:
Does anybody know of a way/utility to batch mode change the pixel density metadata in JPEG files? I have this Phillips digital frame which won't display images properly when the JPEG DPI information is 72, regardless of the real pixel width and height of the images.
Editing it in Photoshop works, but it also rewrites the data of the image, recompressing the JPEG a second time, cumulating artifacts.
Thank you for your suggestions,
Yann

All other applications do what they're supposed to with Windows font settings, so I'm not going to set it to 100% and mess them up because Firefox is weird.

How to edit hidden metadata tags?

Hi, how can I edit the hidden metadata tags used for television (season, episode, etc.) ? I know that iTunes automatically inherits metadata tags from mp4 files, but I am using avi files wrapped in a quicktime media link. Is there a way to do this directly? Alternatively, is there a way to wrap a media link in a mp4 file?

Having looked around, I can only find two programs that support editing these "hidden" tags: Lostify and Atomic Parsley. Lostify is limited to MPEG4 video, and Atomic Parsley is limited to MPEG4 in general (.mp4, .m4a, .m4p, .m4v, .m4b). There doesn't seem to be a tool out there that lets you, say edit the iTunes Music Library.xml file, which would be dang handy.
http://home.comcast.net/~lowellstewart/lostify/
http://atomicparsley.sourceforge.net/
Has anyone come across any other options?
What I find particularly exasperating is that "rational" hand-editting of the XML file seems to have no impact (e.g., I have a bunch of podcast episodes that were downloaded individually, since they had fallen off the end of the podcast RSS... and there is no way to seamlessly merge them into a single podcast stream -- or to kick them all into the "Music" section of the library).
For that matter, short of re-encoding files, it seems that I'm stuck with Apple's decision about which of my files are audiobooks and which are music...

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.

Can I automate the writing of XMP metadata into JPEG and TIFF files?

I have written an ASP.NET 3.5 website application on behalf of an annual international photographic competition. Entrants will be uploading digital photos in either JPEG or TIFF format. Ideally, I would write entrant identity and image title information into the XMP metadata for each image immediately after upload - but so far, I have failed to find any way to do this in ASP.NET.
Thousands of images are involved, so I need to find a way to automate the metadata insertion, perhaps with some sort of script that uses a text file (extracted from the SQL Server database on my website) as the source of the metadata for a batch of images. Is this the sort of task that can be done by writing a script for Bridge CS3? Are there any scripts already in existence that I could use? I am a total beginner in this area.
I use a Win XP PC, though I have a colleague who, I think, has CS3 on his Mac (running under the Leopard OS), so scripts for either platform might be usable.

Index of EXIF-metadata from jpeg files by TREX

Hello,
I have the following scenario:
We have a central fileserver with a lot of marketing pictures. Our marketing people are looking for a solution to search pictures by data stored in the EXIF-metadata of the jpeg-files.
So I like to integrate this fileserver as a repository in KM, set up an index and let TREX do the search (as of note 663630 TREX can search the EXIF-Data of JPEG-Files).
As goodie I want to give the marketing people the possibility to browse through the pictures in an image gallery. This gallery should be consisting of a query-based taxonomy where all the pictures are sorted by special EXIF-data (e.g. name of the photographer).
Until now I have integrated the fileserver (as a FS-Repository) and create an index.
Before index creation I added the mime-type image/jpeg to the TREXValidMimeTypes.ini and restarted TREX.
After indexing the pictures could be found by its name, but the EXIF-data is not indexed.
Now my question:
Why TREX doesnt index the EXIF-metadata?
And how can I use the EXIF-data in an taxonomy?
System:
EP6.0 on WebAS 6.40 SPS16
TREX SPS16 Patch 2
KMC SPS16 Patch 2
Greetings from Berlin, Germany
Jens

Greetings to Berlin,
when triggered by KM, TREX will only index metadata that is known to KM as KM propertis.
I do not know in detail and am not at all sure, but you could try to create custom properties in KM that are called exactly like your EXIF-metadata, set them to "indexable", not fill them with values on KM side and then try again.
You may want to try this for just one of the EXIF-metadata as a test.
Even if that works somehow, the maximum result is:
- Property name existent in KM
- Property thus searchable an classifiable
- BUT property values will not show up in KM, as they will remain known only to TREX
Regards, Karsten

Adding Metadata to JPEG, EPS, PSD, TIFF

Hi all,
I would like to know how if is possible to a read and write metadata (basically Caption and Kewords fields) to a different kind of files (EPS with JPEG compression, TIFF, JPEG, PSD...) WITHOUT opening them in Photoshop.
I need to manage all from Scripting, usually AS or AppleScript Studio.
At the moment I do this opening them, writing them and resaving them but I would like to know if a more faster and professional way exists.
I know exiftool but I would like to use Adobe routine or products.
Stefano

Stefano, I would have thought that 'exiftool' was the best solution for you by far. Never done it but if I recall correctly the developer allows for this to be included in your AppleScript Studio app? The problems that you are going to encounter with the Bridge option are No Access to the Application directly from AppleScript, Bridge is ONLY scriptable via Adobe's ExtendScript/JavaScript. Adobe's other Applications allow AppleScript to perform JavaScript so the ONLY way to communicate with Bridge is via one of these and the BridgeTalk messaging system. Although Bridge will alter the metadata without actually opening the file you will end up launching 2 App's if they are NOT already running. If you don't already know JavaScript then the learning curve for what's involved in this process is considerably more than that of the 'exiftool' man pages. Plus I would expect the performance of calling the shell from your app would blow the Adobe route out of the water… BTMO

Howto Extract Exif GPS Metadata from JPEG?

Hi,
i want to extract GPS Metadata from a JPEG.
The JPEG is a photo taken with an HP iPAQ hw6900 PDA.
Serveral application like exif-o-matic can extract the GPS latitude/longitude metadata.
As described in the Oracle interMedia/Multimedia Userguide "Chapter 6 - Working with Metadata" i use a pl/sql procedure to extract these metadata.
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28415/ch_metadata.htm#CIAEFDGH
I insert a row and extract the metadata but in the exif xml column there are no gps metadata only width/height and so on.
How do i extract these informations?

I got an XML document with no GPS metadata.
With "select p.image.getMetadata('exif') from photos p where id = xx;" i got sys.xmltype(sys.xmltype)
and with "select p.metaexif.extract('/').getStringVal() from photos p where id = xx;" I got an xml string like these
<exifMetadata xmlns="http://xmlns.oracle.com/ord/meta/exif" xsi:schemaLocation="http://xmlns.oracle.com/ord/meta/exif http://xmlns.oracle.com/ord/meta/exif" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Problem writing metadata to Jpegs originating from Macs

Everything works great when trying to write metadata to a JPEG that originates from a PC. But since my company runs a website, we have to be able to handle JPEGs that come from Macs. I've run across an issue where trying to write metadata to a Mac-JEPG causes an error.
Specifically it occurs in TIFF_MemoryReader::ParseMemoryStream(*), where the code tries to find the tnailIFDOffset value. For PC-JPEGs, it returns a sensible value, but with Mac-JPEGS, the value is 0x65005020. Which is clearly beyond the image size.
The result being that no metadata is saved to the image. A workaround is to download the image, open in a PC Photoshop, and try again with that new image. This suggests the problem is in the file structure of Mac-JPEGs.
Does the toolkit support these images? Is there a better code-centric workaround? Do I have to re-encode the image to PC format before I use the toolkit?

Hi,
I have just started working with XMP data manipulation using XMP toolkit.
I am able to read and update XMP data successfully, but not getting an idea to write back to JPEG file.
Is there any API in XMP Toolkit to perform this task?
If not, Please give me some guidelines for this....
Thanks.
