Here’s a review of geotagging tools available as of today (July ‘08). I tested all of them personally and tried to come up with a pro & con list on each of them. If you know a geotagging Mac application that’s not included on this list, please drop a comment. Read more »

I already wrote a few articles about how to use my preferred GPS logging device, the Holux M-241, on the Mac. In this article I’m focusing on the linking process between the GPS data and the photos. This process is called a geotagging workflow. Most of the time I’m taking pictures in RAW mode so the workflow is optimized for this type of images. I’m using a Nikon D80 but the workflow should work with almost any other (Nikon) digital camera like the Nikon D200 or Nikon D300 too. Read more »

Here’s a new HOW-TO to connect your Holux M-241 GPS logger over Bluetooth on the Mac using the BT747 application. Read more »

Geotagging photos is becoming more and more popular since photosharing websites like Flickr, Picasa Web Albums and others support close integration of geotagged EXIF information.

Manual geotagging is a slow and boring process - provided you remember the locations the photos were taken at. I’m convinced that it won’t take long until almost every cheapo digital camera comes with its own GPS receiver that automatically stamps the coordinates into the EXIF header but unfortunately, we’re not quite there yet. So the main question is: how do I get the GPS readings into the EXIF header of the photos in my Nikon D80? Read more »
