![]() The photos are then processed with the gps4cam desktop software. At the end of your “photo trip” you export the GPS information from the iPhone and it produces one or more 2D bar codes, which you simple photograph and add to the photos that you’re planning to geotag. The 2D bar code in the picture is my 1st test of gps4cam and it contains GPS locations sampled on a 5 minute interval of my afternoon photo shoot expedition to Whittier Park. ![]() Primary criteria were low cost, after all this is the post-Christams period, it had to be easy to use, preferably self contained, not requiring yet another online service and be easy to use in my Lightroom workflow. It is possible to geotag photos from DLSRs like the Canon 7D and store that information as part of the image but there are quite a few different approaches and hardware/software options to get the job done.Īfter a little googling around and reviewing a number of approaches, I settled on gps4cam, an iPhone app, to help me get the job done. While iPhone photographs are self-geotagging (GPS coordinates can be automatically associated with the picture when it’s taken) my other cameras, like the Canon 7D, can’t do this on their own. Similarly, geotagged photos sent to photo sharing sites like Flickr use this GPS info to put your photo on the map. You see, Lightroom exposes the GPS metadata of a picture and there is a small little arrow next to the GPS coordinates that launches a Google Map of where that photograph was taken. Well, not so much playing as learning some new stuff in Lightroom 3, which triggered exploring a whole bunch of other stuff, mainly around GPS, geotagging and the iPhone. ![]() I’ve spent a good part of the last day of Christmas holidays playing around with the computer.
