EXIF, the Exchangeable Image File Format, provides a standard way
to store information inside image files. Digital cameras automatically place EXIF information in your snapshots including information about the device used and its color space, among other data. Apple makes it easy for you to view this embedded information
in the Finder. The Finder's Info window includes EXIF data in its More Info pane. To view, select any image file, and choose File -> Get Info in Finder (or just press Command-I). When the Info window opens, click the triangle next to More Info to reveal or hide the EXIF data.
