XMP File

Term: XMP File
Description: XMP, or Extensible Metadata Platform, is a file format introduced by Adobe in 2003. It is used to store metadata that can be read by multiple programs. Metadata is information about a file, such as the date it was created, the author’s name, and keywords that describe the content. XMP files are often used to store this type of information for images, documents, and videos. When XMP files are generated, they are typically embedded within the original file. This enables programs that don’t recognize the XMP format to still read the metadata. In addition, XMP files can be stored separately from the original file. For example, many digital cameras save image metadata to an XMP file alongside the image file. This allows the camera’s software to read the metadata without having to open the image file. Ultimately, XMP files provide a convenient way to store and share metadata.

How to Use XMP Files to Transfer Develop Settings Between Applications and Computers in Lightroom

XMP Files are extremely useful. Because RAW files are so large, it is rather cumbersome transferring them back and forth between computers, or individuals. While RAW images can be anywhere from 10 – 30 Megabytes, XMP files are only around 10 Kilobytes. So, they are extremely easy to share and transfer.

So, if two computers or individuals have all the same RAW files, then develop settings can be passed back and forth by simply sharing the XMP Sidecar Files.

In this video, we are going to talk through some of these practical uses for XMP, as well as show you how to save and pass them back and forth so that you can know how to use XMP Sidecar Files whenever it is necessary to aid your workflow.
