By this time in the trip, I was putting a lot of faith in image processing when I got home.  Chad looked even more featureless than the Sudan.

 

This image is hybrid- before/after of an image from this gallery.  The "Before" image is really what the scene looked like to the eye from the airplane.  The "After" image looks so much like Mars, or even Venus pictures taken by a NASA spacecraft.  This one goes beyond surreal.

 

This probably gets the prize for most detail pulled out of an otherwise totally uninteresting image.

 

The enhancement was really simple- I simply used a tool called Photo Impact, and then only Version 4.0, which is very much out of date.  However, it was simple to use and I just told it to automatically adjust brightness and contrast, and this was the result.  For some reason, Adobe's Photoshop has never done a good job with automatic brightness and contrast.  Strange that such a good piece of software in nearly every other way is so deficient in such a basic task.
