MediaWiki:Exif-imagedescription/qqq

Exif is a format for storing metadata in image files. See this Wikipedia article and the example at the bottom of. The tags are explained briefly and in further detail.

This property is the description or caption of the image. It is used for the exif ImageDescription property, the dc:description property in XMP (see http://www.adobe.com/content/dam/Adobe/en/devnet/xmp/pdfs/XMPSpecificationPart1.pdf ), and the iptc-iim 2:120 caption/abstract property ( http://www.iptc.org/std/IIM/4.1/specification/IIMV4.1.pdf ).

When an image has multiple differing descriptions, mediawiki follows the MWG guidelines when deciding which to show (Which typically means Exif takes precedence).
