I wrote about the idea of synchronizing coordinates from your GPS and your camera by time a while back, and then it ocurred to me that someone must have already done it.

A quick Google query found that sure enough someone had.

I think adding GPS to a camera makes it very bulky (the antenna issue). Perhaps Bluetooth is the answer…

I’ve got a Sony GPS-CS1 GPS logger that I use to record where I’ve been and then later geotag my Canon 5D RAWs and JPGs with.

It was reasonably cheap, takes minimal effort and having location info on all your photos is priceless..

Seriously, having some built-ins is nice. I don’t know why there aren’t more, when GPS can get close to being a $10 chip. But what I probably would really rather have is some expansion slots and at least some rudimentary OS support for a few expansion options. Maybe a pair of co-OSes. One to run the picture-taking properly, and the other being ucLinux that I can hack on to support random hardware devices and other functions.

GPS makes probably the most sense for tight integration, since you want that ready right when you take a shot.

Maybe more realistically, a simple PAN that can have one or more devices feed the camera a current set of EXIF tags (GPS, time sync, what song I’m listening to…), and the camera can send notifications that it just took a shot, light levels, file names, and so on..

Transport could be a few choices. BlueTooth, Firewire, wifi, USB.

Great, now I want to write a camera OS…
