I love the fact that my iPhone automatically geotags photos that I take when I am out and about. Once imported into Aperture, or other photo imaging application that supports metadata, it’s a simple click of the button to find out where on the planet the photo was taken.
But with bigger cameras, like the Canon 5D Mark II, there is a surprising lack of GPS tagging to be found. Oh sure, you could spend several hundred dollars for a GPS system that attaches to the camera, but the ones I have seen are big, and tend to get in the way. Since I always carry my iPhone with me, I went looking for a solution on the App Store.
