A plugin that uses [exiftool](http://owl.phy.queensu.ca/~phil/exiftool/) to read and store extra EXIF values of an image, which WordPress can not on it's own, such as Lens name & ID, GPS location data, etc.

It requires `exiftool` to be installed on the server.

== Description ==

The plugin expands the image meta by extracting data via exiftool. The default set of keywords is:

`-MIMEType', '-FileType', '-FileName', '-ModifyDate', '-CreateDate', '-DateTimeOriginal', '-ImageHeight', '-ImageWidth', '-Aperture', '-FOV', '-ISO', '-FocalLength', '-FNumber', '-FocalLengthIn35mmFormat', '-ExposureTime', '-Copyright', '-Artist', '-Model', '-GPSLongitude#', '-GPSLatitude#', '-LensID'`

which can be altered with the `wp_extraexif_exiftool_vars` filter (one argument, an array with the values above).

Later on the extraced values live in the same place where the default, WordPress extraced EXIF lives and can be access from the same array.

== Installation ==

1. Upload contents of `wp-extraexif.zip` to the `/wp-content/plugins/` directory
2. Activate the plugin through the `Plugins` menu in WordPress
