Columbus nGPS GPS and Remote Cord Combo - Direct Connect Geotagging GPS Unit for Nikon & Fujifilm Digital SLRs So, make no mistake, this is a vastly more intelligent product than the cheap copies you may see elsewhere, which are no more than a GPS module in a box! No batteries required - powered directly from camera The included remote cord adds greater convenience and ease of use in a wide variety of shooting situations, including long exposures and close-ups. The remote also features a lock, which keeps the camera shutter in Long Time Exposure (Bulb) mode. By using a remote cable you can reduce camera shake, which results in sharper images. Geotagged photos may be viewed on Flickr, Google Picassa, Apple iPhoto, Yahoo!, Photoshop Elements, and many other photo viewing apps that can display EXIF header values. Photos uploaded to Flickr or Picassa network albums can get mapped automatically to the Google or Yahoo maps.
