need a little help ... on making height maps ...

[genblood]

I tried terragen to make my height maps ... but they don't
come out to good. Is there another way to make the height map?
If there is, what's the app and can you give a quick run down
on how its done ..? An any other tools I should be using ...
Any input would be helpful ...
