`This module maps elements from the {EXIF} namespace[1] to GData objects.
These elements describe image data, using exif attributes[2].
Picasa Web Albums uses the exif namespace to represent Exif data encoded
in a photo [3].
Picasa Web Albums uses the following exif elements:
exif:distance
exif:exposure
exif:flash
exif:focallength
exif:fstop
exif:imageUniqueID
exif:iso
exif:make
exif:model
exif:tags
exif:time
