This doesn't help directly with constructing any command lines you might use, but I found the "Gentle Introduction to GDAL" series by Robert Simmon very helpful in determining what to do.<br>

In my memory I have a similarly written article on gdal colour balancing that did have some command line examples but I can't relocate it at the moment. It annoys me that I can't reference it so I'll keep looking. ;-)<br>
