I was sitting in front of the computer and thought I would try it.I used Photomatix with pics taken from my cheap 6MP camera.I combined 3 shots and fiddled around with it.Don't know if I did it right but here is what I came up with.
Before
After
I am not sure how to get rid of the water marks as it is a trial version.Anyway,am pretty interested in this and will try more.
