A CDE Definition
(EXchangeable Image Format) Descriptive data (meta-data) in an image file that include the date the photo was taken, resolution, shutter speed, focal length and other camera settings. Developed in 1995 by JEIDA for JPEG images, EXIF data was later added to TIFF, RAW and other formats. Most digital cameras support EXIF and save the data in the file headers. However, when an image is edited, the EXIF data may sometimes be removed by the software.
EXIF Dates May Not Be the File Date
When photos are downloaded from the camera into the computer, the date assigned to the image files may be the date the photos were taken (EXIF date) or the date the photos were downloaded. Photo viewers may sort photos by the internal EXIF date without regard to file dates or name order. For example, Apple's iDevices sort photos by EXIF date. In order to be displayed in a different sequence, they must be rearranged in Apple's iPhoto application on the Mac and then downloaded.
An EXIF Reader
(GEOgraphic REFERENCING) The inclusion of geographic coordinates in a digital map of an area. Georeferencing typically adds longitude/latitude meta-data to pixel locations on a map image. The EXIF meta-data format for camera photos also supports GPS coordinates. See EXIF and UTM.
