James Duncan Davidson at Inside Lightroom has happened across a hidden little gem in the app–namely, the ability to play audio files attached to photos. Some high-end cameras, especially those geared towards photojournalists (e.g. the Canon 1D Mk III), allow a shooter to record voice notes that get attached to images, becoming essentially part of the images’ metadata. Lightroom 1.1 quietly introduced the ability to recognize & play these annotations. It’s a cool way to take notes in the field, then access them while reviewing photos.
In a related vein, Lightroom also recognizes embedded GPS metadata & offers the ability to display the location via Google Maps. Ian Lyons has the details.
