IPTC study shows Social Media Networks Remove Metadata


We support the Embedded Metadata Manifesto
As visitors to the PhotoMetadata website know, digital camera files contain more information than just a stream of pixels. Even basic photo editing software, like those covered in the site's Meta Tutorials, allows photographers to embed rights-based information (like a Copyright Notice) and other descriptive information. However, you wouldn't know that from looking at pictures on many social media sites or after downloading them from photo sharing sites. According to a new study just released by the International Press Telecommunications Council (IPTC), major social networks like Facebook, Twitter or Flickr remove copyright information and other useful embedded data from pictures posted by their users.

"A social networking site is only as good as the information its members choose to share. If users provide rights data and descriptions within their images, these data shouldn't be removed without their knowledge", said Michael Steidl, Managing Director of the IPTC, a consortium of the world's major news agencies, news publishers and news industry vendors.

Every day, more and more photos are shared over social media. IPTC was approached by users who discovered that when they shared photos, their embedded metadata disappeared. Earlier this month, the IPTC Photo Metadata Working Group tested 15 social media sites to understand how image sharing, through upload and download, affects the integrity of embedded metadata as defined by IPTC standards and the Exif standard. The results of these tests can be seen at www.embeddedmetadata.org/testresults

The full news release about the Social Media Study is available from the IPTC website.

New Site Launched to Encourage Embedding of Metadata

We support the Embedded Metadata Manifesto

A major initiative to encourage the direct embedding of descriptive and rights information into all manner of digital media has just been launched. Photometadata.org endorses the effort and is helping to spreading the word.


“A picture may be worth 1,000 words, but permanently attached descriptions are worth a lot more as photos travel through the digital world. A campaign has been launched now to embed descriptive and rights information in digital media and to retain it during the whole life cycle.

The initiative has been launched by the International Press Telecommunications Council (IPTC), the American Association of Advertising Agencies (4A's), and the Association of National Advertisers (ANA), with the support of trade organisations representing visual arts and photo agencies. It aims to establish the practice of applying descriptions and the copyright status of the content as metadata, and to embed it permanently during the electronic exchange of digital photo, text, audio or video files.

This practice is based on the principles defined by the Embedded Metadata Manifesto on the web site www.embeddedmetadata.org which invites organisations and individuals to support the campaign.”

Why can't I insert metadata at the capture stage?

Mike Ashenfelder from the Library of Congress interviewed me recently for an article on their website Titled "Mission Possible: An Easy Way to Add Descriptions to Digital Photos." He was asking why adding information (metadata) to images is so difficult. I told him that this was an issue I had raised at the First International Photo Metadata Conference in 2007. I noted that photographers need ways to insert metadata as early as possible in the process; and asked why it wasn't possible to have some device that could be used to input information and tag it to the images I was shooting at the time of capture. There were engineers from Canon and Nikon in attendance, and it seemed that they understood the question, but I'm not aware of any progress in this area.

However, since manufacturers and developers do seem respond to input from those who purchase their products, perhaps what is needed is a grass roots appeal? With that in mind, I've included details on how to contact several of the larger digital camera manufacturers. If a number of you contact them, asking if they are working on improvements on how metadata (information) can be added to the Exif or IPTC at the time of capture, perhaps something will change?


Ask them "Why isn't there a 'Add Description' button for my camera?"

Can Embedded Photo Metadata Help Your Website SEO?

There have been a number of recent articles pushing the idea that embedded photo metadata can boost your search engine ranking. However, while the practice of adding embedded metadata to increase findability and to protect the intellectual property of an image are both good ideas, there is a hitch to this concept from the Search Engine Optimization (SEO) perspective.

That is, while it is possible for automated search bots to be configured to read the embedded photo metadata embedded in digital images, there is no evidence to suggest that the search engines are currently doing this; nor is there any evidence that it will help with the SEO for your images or your website — at least not without some additional work. That doesn't mean that embedding metadata in your images is not a good practice. It's just at this point in time that it has little value for Search Engine Optimization (SEO).

Read more about what can be done to leverage your metadata work in the article "Why Embedded Photo Metadata Won't Help Your SEO."

Myths about photo metadata?

How savvy are you about photo metadata? There are a number of myths or misconceptions that surround the practice of embedding copyright, contact information, and other types of “metadata” into digital image files — like JPEGs, TIFFs, Photoshop, DNG and other Raw files.

Take a look at the list of the Top 12 myths about embedded photo metadata and see if you can tell which are fact and which are fiction.

Here are the top five:

1. Embedded photo metadata is something that is hard to read unless you have Photoshop or some other professional software application.
2. Embedding photo metadata adds a lot of disk space overhead to an image file.
3. Removing embedded photo metadata is against the law.
4. Images that I upload to my social media or photo sharing sites will still retain my embedded photo metadata.
5. Images that I upload to my social media or photo sharing sites will still retain my embedded photo metadata.

Read the other 7 statements in the list as well as all the detailed commentary on the Controlled Vocabulary website.

facebooks new photo sharing fails Photo Metadata testing


I heard on CNET's "Buzz out Loud" Podcast last week that Facebook had updated their photo sharing to accommodate "High Resolution" images.

You can now upload images up to 2048 pixels on the long dimension. Note that I said "upload" -- not view. Your facebook friends (or other viewers if the album is made public) can download these larger sized images, but the online viewing is limited to a version that has been resized to a maximum of 720 pixels wide. I had hoped that this integration of Divvyshot's technology might mean that facebook would finally stop their "stripping" of embedded photo metadata, but that apparently is something that facebook users will still have to lobby for if they expect to see a change.

I've made a facebook album page available for public viewing using the CV Social Media Testbed image, which was fully loaded with embedded metadata. The actual image (now sans metadata thanks to facebook) can be viewed at this link. http://sphotos.ak.fbcdn.net/hphotos-ak-ash2/hs316.ash2/59589_455012177944_532727944_5452967_4191590_n.jpg

As noted in the latest report on the "Survey regarding the Preservation of Photo Metadata by Social Media Websites" no metadata from the image is exposed on the facebook site. While there is an option on your facebook page to "Tag This Photo" the system does not pick up any of the embedded metadata tags such as those in the keyword field, like both flickr and Picasa Web Albums can do.

In addition, while the images that can be viewed online are now up to 720 pixels on the long dimension, they are still being "stripped" of all IPTC, XMP, and Exif metadata (ICC profile information is retained). The option for others to download a 'high resolution" version, only prompts a download (you can not view the image online). I downloaded this larger version and tested as well. The only difference between the "high resolution" version and the online 720 pixel wide version, was the resolution -- both are stripped of any information beyond the pixels and the ICC profile. Since all descriptive photo metadata is missing, this would mean that even the "original" is being modified before it is stored on their system -- and potential orphan works are being created, each time you upload an image to facebook.

For those that are concerned about retaining their intellectual properly, facebook receives a failing grade in our book. For now, our recommendation is to stick with Flickr or Picasa Web Gallery.
