Lets look at a few images I made with Terragen 1 (with no extra photoshop-like touches):

This is a weird looking landscape I made in Blender. It's deliberately strange looking, by the way! Check out the water. Looks good, eh.

Heres another landscape. Again some nice looking water. Remember Terragen can make animations so you can do flyovers and fly-pasts and the like....

Here's an image that reminds me of my home country Ireland. Gentle rolling hills, grass, ehm, that's pretty much it...

Heres a Himalaya type Everest view of a snow covered mountain. Terragen's sun settings and cloudscapes can all be animated so you can have the scene animate from day tyo dusk to night if you want!
Terragen is for "Non Commercial Use Only" and can be downloaded for free. Also check out Terragen 2, which is still in it's pre-release version.
