Last week’s 2019 IPTC Photo Metadata Conference was again hosted in association with the CEPIC Congress. This year’s conference was held in a slightly rainy Paris but at least that meant that we didn’t mind staying indoors in late May.
The event kicked off with an introduction from event chair Stéphane Guérillot from AFP, who is also on the Board of IPTC and Chair of the IPTC Standards Committee. The theme of the afternoon was “putting IPTC metadata to work for your image collections” and the emphasis on practical outcomes was a constant refrain.
The first panel was around the question of “do we still need IPTC Photo Metadata?” Michael Steidl, lead of the IPTC Photo Metadata Working Group started off by presenting results from the IPTC Photo Metadata surveys that the Working Group has undertaken earlier this year. Lúí Smyth from Shutterstock showed how metadata has helped them to organise millions of photos from thousands of sources. Isabelle Wirth, photo editor at AFP discussed how the agency uses IPTC Photo Metadata along with other IPTC standards such as News Codes and NewsML-G2 to make content searchable and shareable for their clients. And independent photographer and 3D photogrammetry expert with Deep3D, Simon Brown, explained how metadata was crucial for creating 3D views of sunken shipwrecks via tens of thousands of still photographs and some innovative software. In Simon’s words: “For more than one 3D project, projects with multiple contributors, or projects conducted over a longer period of time, IPTC entry becomes mandatory.”
The next session examined how creating and editing IPTC Photo Metadata could be improved. Sarah Saunders representing CEPIC presented results from the IPTC Photo Metadata surveys of both image suppliers and software makers showing that metadata usage has grown in sophistication but still varies greatly between independent photographers and large companies. Andrew Wiard, photographer and member of the British Press Photographers’ Association, spoke with passion about how we could improve the handling of photo metadata once it leaves the photographer’s desk, a constant goal of the Photo Metadata Working Group and which will form part of our work plan for the rest of 2019. Mayank Sagar from Image Data Systems showed some exciting tools with videos showing how their AI algorithms can detect objects from luggage and handbags for commuters to brands and logos on advertisements in sports footage, and talked about the current limits of AI classification and future issues such as how to handle artificially synthesised images. Andreas Gnutzmann of popular photo management software Fotoware showed how their system is moving to the cloud, putting metadata at its core even more than previously.
The third session looked at the end-user side and how the industry can benefit from photo metadata. Brendan Quinn of IPTC presented the Photo Metadata Crawler project, examining how news publishers around the world are embedding photo metadata in the images used on their sites. Michael Steidl showed results of the Photo Metadata Working Group’s updated analysis of social media systems and sharing platforms, which will be shared through an IPTC news article in the coming months. And Anna Dickson of Google gave us an update on her history working with images as photo editor at Huffington Post and Dow Jones among others, and discussing how Google are working with metadata and the IPTC, including our shared challenges of encouraging more site owners to publish embedded metadata so that it can be picked up by Google Search and other services. At the event, Google also announced some very interesting features that are currently in the pipeline.
Michael Steidl and Stéphane Guérillot closed out the event talking about the work the the IPTC Photo Metadata Working Group would be undertaking this year as a result of the discussions and of the survey results.
All slides from the day are available in PDF format from the event page, both to IPTC members and non-members.
Key findings from the Photo Metadata surveys will be shared in future news posts, so please watch this space for updates.
More information about the Google presentation and their proposed new features around image metadata is available to all IPTC members who have joined the Photo Metadata Working Group.
Thanks to all the speakers, to CEPIC for their assistance in hosting the conference, and to everyone who attended for making the event such a success!

Ten years ago, the very first IPTC Photo Metadata Conference in Florence was packed with photographers and picture libraries eager to discuss ways of protecting their work in the digital environment. The image industry has expanded enormously since. The image industry has the additional challenge of vast numbers of images crowding the web, and the difficulty of finding the relevant picture, as well as the metadata relating to it.
IPTC Photo Metadata Conference 2017 was designed to look into the future, with a focus on image search using AI or Artificial Intelligence. The ability of computer systems to learn from humans has increased enormously in recent years, and the necessary computer power has now become available. The question for the conference was – how far can these systems help the professional image industry sharpen up its search capability and make gains in productivity?
Solution for Auto Tagging in the Image Industry
Kai-Uwe Barthel, professor of visual computing at HTW Berlin University gave a clear exposition on the history of the field and of the pressing need to create solutions for the picture industry. There are now too many images for classical search systems to handle, but using Neural Network Analysis – a variant of AI – computer systems can be taught to tag and recognise images in a fraction of the time it takes to manually tag. As most online images are untagged, a combination of human tagging and visual similarity search presents a viable way forward. But Barthel and his team have also researched new methods of presenting images, using three dimensional structures to dig into results with large numbers of images visible at one time.
Speakers on the use of AI came from across the industry, presenting solutions which can be put into practice now. The key to success in this area is to have enough content for the computers to learn from, and this can be achieved in a number of different ways. General AI systems produce good results for skies and beaches and general themes because they’ve had the data to learn from. But users can set a system to learn from their own content so that more specialist content can be tagged if the conditions are right. Computers are learning faster, and need fewer images to learn from than before.
AI systems can be trained to recognise faces, text, colours, composition, scenes, and objects, but can also be trained in the aesthetics of image selection, with one speaker maintaining that twenty images are enough to train a system in a particular brand aesthetic. But speakers admitted also that defining the precise location of what is shown in an image by its content was tested but it did not work in a reliable way.
Speakers stressed that the important element in computer learning is the understanding of the nature of the material to be tagged, an attribute which is currently not about to be taken over by artificial intelligence. The benefits in speed and productivity will be enormous but we’re not yet talking about doing away with human skills altogether!
IPTC Video Metadata and Easier Cross Media Distribution
The first afternoon session by IPTC Managing Director Michael Steidl was about the IPTC Video Metadata Hub (VMH), published in 2016 to provide a standard set of fields for use across the varied technologies used in video. Many of the Video Hub fields are equivalent to those in IPTC Photo Metadata Standard, which helps streamline cross media distribution. The VMH can be applied down to the level of video clips, which makes it a useful metadata tool for production, archive and distribution.
Technology That Protects Rights Information in Google Image Search
The IPTC conference was held a day after a CEPIC seminar on Google. The Google image search scrapes images from their original sites and displays them in its own environment. This is bad for rightsholders as images can be saved and downloaded direct from Google without reference to the original site. Picture libraries and agencies lose significant traffic to their sites as a result with a German agencies survey indicating a drop of 50 percent in traffic. The recent fine levied by the EU on Google for anti-competitiveness in comparative shopping sites is encouraging and has paved the way for scrutiny of Google’s actions with online images.
The second presentation of the afternoon presented a solution for the problems raised in the Google seminar. SmartFrame technology allows images to be presented online without the danger of being scraped by Google as this is disabled by technical means. Most of the mechanisms people use to download images – like right-click – are disabled too. Images can be shared as links so social media sharing doesn’t lead to an image becoming orphaned and lost in the websphere. And when an image is viewed as a thumbnail in Google, there is a clear indication that it is a copyrighted image, and a link back to the originating site. Rob Sewel, Pixelrights CEO demonstrated how product items within an image could be linked back to a brand website, providing ways of funding photography in the future where photography provides a link to a paid-for advertising service. The technology could be put to all sorts of uses in both commercial and non-commercial fields, and gives control back to creators and their agents.
The success of this kind of technology, as with all solutions to image grabbing and orphaned images, lies in the uptake of the technology. To be truly protective of copyright, client websites would need to implement a technology like SmartFrame.
The IPTC Photo Metadata Conference 2017 was fascinating from start to finish for the about 60 attendees on location, the level of presentations was extremely high, and the presentations and videos are all available on the website at https://iptc.org/events/photo-metadata-conference-2017/.
