I learned about Microsoft Pro Photo Tools a couple of months ago when researching ways to geotag my photos. Version 1.0 of the software allows you to easily edit the EXIF and IPTC meta data of your JPG images.
After using the tool for a couple of months I have reverted to using the tried-and-true Exifer to add copyright, contact, and descriptions to my images. I feel like Microsoft Pro Photo Tools does not make it clear exactly what it is I am editing, EXIF or IPTC.
But what this software does excel at is geotagging. Under the Map Browse tab is an interface to Microsoft Virtual Earth that allows you to select one or more images and place them on the map which assigns latitude and longitude coordinates to the EXIF data. Very quick and easy compared to other tools I have tried on WindowsXP.
The geo info tagged in the EXIF data allows services such as Picassa, SmugMug, Flickr, Panoramio, and many more to place your photos on maps for users to find them by browsing maps. I highly recommend checking out the new “More… Photos” option in a Google Maps search.
