Maps the Carmen way

Carmen's Fun Painty Time! has a nice little tutorial on making a map using Photoshop elements.  Often I struggle with various open sourced software, and here is a little tutorial that makes the comerical products seem so much easier...  I assume having artistic skill helps a bit too (you no doubt recall my crude efforts in this area)

Anyway, here is his very fetching final product, a wastelands area map, which would be perfectly servicable for a miniatures campaign, or a roleplaying exploration map. Throw on a hex grid, and you are good to go.
