Steven. the process they mention is what I already do
1) have a track log running
2) hook GPS to computer (or actually the mini-SD card inside it)
3) download pictures, at which time, the coordinates are written to the EXIF based on the gpx tracklog
The Jobo seems the same
1) take Jobo and hook it to computer
2) download photos to folder
3) run Jobo software and point it to that folder and it'll tag them.
Same number of steps, just different order. and once again, the Jobo, if working as advertised, will mark when the picture is taken
Although, that confuses me. How can the GPS work that way? If the camera thinks a flash is up there and sends a fire signal, which is what the Jobo needs to mark a waypoint, then wouldn't the camera be meter a bit wrong? Do you always have to have the flash 'on' for it to work? otherwise, how does a flash or the jobo know when the shutter is tripped?
