Alright, I'm a total photography noob eventhough I like looking zt this form of art I have no idea about technique behind the photographs etc.

I've heard some stuff about HDR. I have no clue what it is and would like to get a bit informed about it?

Can anyone tell me what this (feature/technologie?) is?

Im sure Nemesis or Freaky can illuminate us on this subject :)

Hehe I've typed up at least 5 post today alone on another site.
I will be writing extensive tutorial on HDR and tonemapping over the weekend but in the meantime read this:
