Editing IPTC & Metadata

Boosting your SEO with built-in tools

gallcoll-settings-IPTC-pane.jpg

Image metadata is the set of data that lives within an image file that describes the image's attributes -- everything from the photo's size to its resolution to its copyright information and beyond. Particularly for images on the web, metadata provides an essential role in describing, tracking, and identifying the image.

Metadata also factors significantly into SEO (Search Engine Optimization), as fields such as image captions, headlines, and keywords all help describe the contents of your image to search engines. Throughout PhotoShelter, you'll see a green SEO symbol placed next to metadata fields that are relevant to SEO.

PhotoShelter allows you to edit both the descriptive and administrative metadata for your images, both individually and in batch. 

 

IPTC

IPTC (International Press Communications Council) is a consortium of the world's major news organizations. One of their main goals is providing standards to facilitate information interchange between organizations. As such, they have developed a very complete way to annotate an image with metadata. For example:

  • Description/Caption

  • Copyright

  • Author

  • Keywords

  • And much more

PhotoShelter fully supports the IPTC Core specification (see below), which means annotations you create in programs like Photoshop will automatically be read and extracted upon upload. More importantly, if you change the metadata in the file in PhotoShelter, we will re-embed that information into files when you allow others to download them.  

When a keyword search is accessed on your PhotoShelter website, these are the searchable IPTC fields:

  • Filename
  • Description/Caption
  • Title 
  • Keywords
  • City 
  • State
  • Country
  • Country ISO

IPTC Core

IPTC worked with Adobe to come up with a more robust specification that added more fields and also standardized the way information was written to a file using XML. Beginning with Photoshop CS2, the full IPTC Core is accessible through the File Info panels (File → File Info). You can also use the IPTC Core with Photoshop CS by downloading the panels from the IPTC website.

Other programs like Photo Mechanic and Adobe Lightroom also support the IPTC Core standard. Older programs will support a 1990s version of the specification, commonly referred to as the IIMv4 (Information Interchange Module version 4) specification.

The full specification that describes each field can be found on the IPTC website.

EXIF Data

EXIF (Exchangeable Image File) data is the set of information assigned to your image by your camera. This information, which includes date, location, and time info, your camera settings, shutter speed, focal length, etc., may be viewed in the Right Pane of your Image Browser any time an image is selected.

EXIF data may not be edited through PhotoShelter.

 

Additional Info

It's important to note when you enable downloads of low-resolution comps, high-res downloads, the original file, or another specified size JPG, the file will be downloaded with all updated metadata embedded. But be forewarned that the file size can grow dramatically depending on how much metadata you have. It's not uncommon for the metadata to double, triple, or quadruple the file size of a low-resolution files.

  • Your original file that was uploaded to PhotoShelter is never altered in any way. You will always be able to retrieve the exact file you uploaded.
  • We do not currently re-embed metadata in PSD files and some raw files.

PhotoShelter allows you to edit both the descriptive and administrative IPTC metadata for your images, either in a batch or individual images. (EXIF data may be viewed but not edited.)
