Current attempt at the GPS Circut...

On the road its great to be able to get GPS info attached to your photographs. Pretty simple for Nikon dslrs, a pain for Canon.

A solution I've been playing with is based on HoudahGeo and a Wintec G-Rays2 GPS logger, which attaches to your computer - not your camera - your computer via blue tooth or USB to reconnect time juxtaposed gps travel logs with the times the photos were taken.

The results are... mixed.

When the tracking is good, you usually get pretty good results. In dense city areas, there seems to be quite a bit of noise in the log, and some dithering is required. There are ways to do this, but the amount of work required offsets the "enjoyment" factor.

Then there is the issue with the clocks.

This particular logger does not allow you to change time from the display. If you change time in camera, you have to keep in mind to do so in the software later to match coordinates.

If you travel through different time zones, keep your photo sessions separate - or confusion is guaranteed!

More to come..
