Anyway, I discovered that by combining a "Clouds" filter, a "Posterize" adjustment, and a "Find Edges" filter, I was able to create my own fictional countries! Without having to draw a thing!
I decided the countries I had created looked pretty flat, so I added a "Bevel/Emboss" layer-effect to make the landmasses "pop out" a bit more.
Finally, the finished product, with every single area having their own names. "How did I come up with such fantastic fictional names" do you ask? I named the countries and bodies of water based on what font-type they were. In Photoshop CS4, there is a smorgasbord of fonts to choose from, such as Pristina, Nyala, Palatino, Latha, etc.....the only place whose name doesn't match the font it's set in is the Wing Ding Islands. If they were really in Wing-Ding font, you'd just see shapes and symbols.There you guys have it! The Wonderful Fantasy World of Fontasia, where the names are based on fonts! If you're an artist or a writer who'd like their very own world to rule over, and you own Photoshop or some other graphic software with similar filters and effects, then play around with the steps I've described. It's a fun way to spend a creative couple hours.
