In syncįor the most part, this synchronization “just works” and you see the metadata that you should see. Applications can keep all this data in sync if they feel like it. Some can copy your IPTC Caption to the Image Description field in Exif. We’ll ignore those.) Some applications can read your copyright information, for example, and copy it to the relevant IPTC field. The Exif fields that applications might write to are for copyright notices, the image creator’s name, and the “Image Description” – a caption, in other words. Generally, while anybody can write Exif information to a file, it’s cameras that do so. Exiftool shows the three locations where caption information may be stored in your metadata. Modern, upscale, cameras can write your byline and copyright information to fields in Exif.

The Exif format stores mostly logging information from your camera, like the camera’s serial number, settings used to make a photo, and GPS coordinates. On top of that, there are a few “IPTC-ish” fields that can be found in the Exif data, as well. Watch the video version of this post Then there’s something in Exif… It’s up to your metadata authoring application to keep the two copies of IPTC data in sync between the two formats. One day, the IIM format will be phased out and everything will be more or less under one roof in XMP. Copies of the basic fields live in the XMP, too. Then there are the extended IPTC fields, which live elsewhere in the file, in the newer Adobe XMP format. Physically storing the data in the file is a separate pile of acronyms.)

Actually, the IPTC specifies what kind of information is stored in its “properties”. (Some people mistakenly think this is all there is to IPTC metadata. Because all things that should be dead simple usually aren’t, the IPTC metadata – important information like the caption, your byline, and copyright notice – is stored in multiple places in your file.įirst, there’s the old-school IPTC/IIM version of the basic info. Let’s step back for a moment for some background. Which instance of the IPTC metadata does your favorite application prefer? Inquiring minds want to know. Your important metadata lives in two, maybe three, places in your file which one are you seeing? We took a deep dive to find out which ones are preferred by various applications. Your metadata may be stored in multiple places in your media file.
