Let your iPhone do the GPS heavy lifting, while you and your camera focus on the art.

The iPhone’s integrated camera and GPS hardware is match made in heaven for use with the Places feature in Aperture and iPhoto. But what if you prefer to use a point-and-shoot or DSLR without built-in GPS? You could purchase a GPS peripheral for your camera or add the location information to each photo manually—or give gps4cam a try.

This iPhone app interacts with your iPhone’s GPS hardware to tag your photos by time, date and location. Just open the app, tap the Start a New Trip button, and gps4cam will track your every move automatically at 30-second or 5-minute intervals, while you happily shoot away with your big-boy camera. You can give the iPhone a quick shake to manually capture your current location, and Google Maps is baked right into the app too.

Shoot this with your camera, then let the gps4cam Mac application geotag your photos.

Once your photo excursion is over, press the Export button in gps4cam, which generates a bar code that you simply photograph with your camera. Then you use the free companion Mac application (from gps4cam.com) to upload your photos to your Mac and automatically geotag them before you import them to your photo editor of choice.

The bottom line. It works well, but we have one niggles with the interface, although it does look an awful lot like the screen on a high-end camera. We’d like to see a running total of locations recorded, instead of a tally we need to manually count. But that’s a small complaint considering how great this app is already.
