Wow. It is not often you find a really simple, low cost app that really solves a problem. I just tried out Geotag Photos Pro with Lightroom 4.

I've been looking for an inexpensive and easy way to get GPS tagging into photos that I take with my Nikon DSLRs. One solution is to buy a GPS tagging device (there are a few out there), but they are typically bulky, chew up battery and they cost more than $100.

With Geotag Photos Pro app on my iPhone I synched the time with my camera, then started tracking my movements. It does consume more battery on the iPhone, but not too bad. I then take photos. When done, I loaded the track onto the Geotag web site. Later I imported my photos to Lightroom 4 and imported the tracking log. Lightroom then inserts GPS coordinates and does a full lookup of the address and inserts that detail into every photo.

There are options on how often the app logs your location - more frequent consumes more battery. You can email or upload the logs, and it gives options on accuracy - all well explained in the user guide.

I love this app and I can't wait to test it out when I travel.

There is a more complete description of the app and using it in Lightroom by Terry White here.
