As a rail photographer, I consider myself to be a historian of sorts; I try to capture today so we can all remember it tomorrow. As such, I want to capture as much detail about my subjects as I can. As a purely digital photographer, I want to extract the maximum amount of information from my digital photos. A GPS receiver in my camera would allow me to capture the exact coordinates where all of my photos are taken and record them along with the usual metadata in the photos.

When I post them to my gallery, I could link to a Yahoo! map with the locations of my photos plotted out to make an automatic railfan guide!

Simply put, having the exact location a particular photo was taken (in addition to the usual date, time, and other metadata) helps future viewers better see and experience that moment in time. And we'll never have to wonder where that photo with no label was taken. And it's all done automatically.

Sounds awesome to me.

I guess all we need now is to get the GPS receivers small enough and cheap enough...
