Yes- Agiel, that's a GREAT reference link. Anyone who wants FREE HDR files can get LOTS MORE- and many are VERY GOOD. You don't have to buy the Dosch sets unless you really get SERIOUS about HDRI rendering- which obviously I AM! (heh!)

I'm a real FANATIC when I get into a new subject that fascinates me. ...Sorry to be so EXASPERATED trying to explain this!
