PC World has reported on Sony’s GPS-based photo-location tagging device. Whilst no surprise, it’s interesting that it’s self-contained, rather than built into the camera (so far). Not so sure about the 10-hour battery life – seems a tad short. But yes, it’s useful, especialy for archivers. Many times I’ve wondered exactly where a photo was taken, and as long as we can shake off the “print” mentality that wastes paper – and actually use our digital images as our one true source, we’ll be OK. I’m sure GPS will be included in cameras real soon now, as well as all mobile phones, bicycles, cars… you name it. Now where did I park that car? Oh yes, simply “ping” the car’s GPS unit to bounce the location back to your cell phone and Bob’s your uncle. Same for bikes. It serves the double purpose of letting you know where you are, of course, and possibly avoiding traffic and other hazards. It’s a luxury but a nice one.
