This is the story of a photograph of Montserrat. It was taken by a crew member of the second expedition to the International Space Station, "Alpha." The photo was taken from the crew window of the Destiny module as part of the Crew Earth Observation (CEO) experiment. This particular photo, number ISS002 ESC 9309, was taken on 9 July 2001 as the station passed several hundred miles north of the island.

Ever since I did a similar thing on another photograph, I've enjoyed playing with aerial photos to see what can be done with them. In this case I attempted to both remove the blue atmosperic haze and "correct" the perspective distortion in the photo to yield a pseudo-overhead view.

Just as soon as I had completed that project, I was bombarded with questions asking how I had done it. I decided to go back and produce some documentation to accompany the processed photo. The documentation process became a full-fledged project itself with this set of pages as the result. Below to the left you will find a QuickTime movie visually illustrating all of the steps in the process. To the right is a "Do-It-Yourself" page that explains each of the steps in enough detail that a person familiar with Adobe Photoshop could duplicate the process.
