Yesterday, we took a look at what photo metadata is, why it’s important, and how it benefits photographers. The information came out of a presentation on metadata by ImageSpan with liveBooks and the Bay Area-based Renegade Meetup photography group that drew nearly 30 photographers to an after-hours event at liveBooks last Wednesday evening.
Today, we’ll continue to share what we learned in that Metadata Meetup. We’ll touch on how to apply metadata, how to make the application of certain types of metadata more efficient, and why applying metadata is critical for your business. We’ll also include links to websites where you can learn more about metadata.
Attaching Metadata
There are several ways and methods for attaching metadata to an image. In addition to embedding metadata as images are published to the Web, through services such as LicenseStream and liveBooks, photographers can associate metadata in several other types of photography workflow software, such as Adobe® Photoshop® Lightroom™ . In fact, photographers using Lightroom and the popular Adobe Creative Suite® 3 software can upload all of their images along with metadata applied in those programs to LicenseStream via plug-ins.
Travel photographer David Sanger, who presented a great overview of what metadata is and how it works, said that there are instances where social media sites will strip out metadata. He added that even some major search engines will not look at metadata to help anyone searching for an image find it.
To ensure that the image is searchable, Sanger recommends photographers associate a caption as well as keywords with their images. Search engines, Sanger said, “primarily look at the text on the page associated with an image.” That said, he added, “If somebody finds your image and the metadata survives, then they can identify the image as yours and they can license it.”
Applying Keywording
Brian Pobuda, a corporate photographer who also consults as a digital asset management specialist, said that to make applying metadata more efficient, he often applies a first round of basic keywords to a group of content. For a recent shoot, for example, he labeled a batch of images “City Center, Las Vegas, 2010,” and then applied more specific keywords to those images he expects clients to use.
Sanger said his keywording practices depend on the image destination.
“For example, with Getty I provide conceptual keywords and they do the rest of the keywording,” he said. “When I know an image will be put on Google Images, I want lots of keywords because I want as many people to find it as possible.” Other stock agencies may penalize you for having too many obscure keywords, he added, because your ranking depends on your click-through ratio which may fall if too many obscure keywords are attached.
There also are situations when additional keywords may not be desirable.
“If I have a picture of a sunset, it won’t necessarily say 'San Francisco, Baker Beach, June 2003 sunset 4 p.m.,'” Sanger said. “I may just say 'Sunset on Ocean,' because an image buyer may just be looking for a generic image. Similarly, he doesn’t always apply a date. “There are times specificity can work against you,” he said.
PCWorld Senior Editor Melissa Perenson, who served as moderator at the Metadata Meetup suggested a good, common-sense method for applying keywording. “Just think about how you would find an image if you were doing a search,” she said.
In fact, keywording specifically and metadata applications generally can still vary widely. Major stock agencies all have their own methods of applying metadata. Some use IPTC – a standard that came out of the newspaper world. A more advanced standard which includes additional fields emerged when Adobe moved to XML, Sanger said. “Then there is a third way to do it, which is to have the captions or metadata in a sidecar which is a separate XMP file that can accompany the photo,” he said. In addition, there’s a fourth standard called Dublin Core®.
Because there is not yet complete standardization as to what fields are used by various agencies or within various software programs, Sanger said, “it helps to stick with the simple ones that are used in your tools unless you have reason to delve more deeply into it. You can overdo it.”
As for keywording hierarchies, Sanger recommends Controlled Vocabulary, a site run by metadata master David Riecks. “David's site not only has more than you need to know about structured vocabularies,” Sanger said, “he also has links to a variety of products that will allow you to structure your keyword hierarchy.”
A Critical Tool for Tracking Your Business Efforts
While metadata is used to identify, license and monetize images, Sanger also suggested photographers think of metadata as information needed to operate their businesses. It can include your sales results, where the images have been submitted for licensing, where the images have been sold, which stock agencies or services have a certain image or group of images, and which clients commissioned them.
“This is important information because if you have an exclusive contract with one agency you have to know which images are with that agency and can’t go elsewhere for sale or licensing," he said. "While that information isn’t usually in the image itself, the ability to track sales and revenues relies upon identifying which images have been sold or licensed. It all goes back to the file name or the ID portion of the file name.”
Finally, for additional information on metadata, Sanger suggested the following sites:
