While this DOES make an HDR file- based upon what I've seen, read and tried, the "Do It Yourself" HDR files are not nearly as good as the Professional Grade stuff created with specialized cameras.

A lot of this HDR Free Stuff are older experiments done with the mirrored balls, etc.- but since MANY of these people were basically college students 2-5 years ago using cheap, gardenshop props to validate their HDR theories and develope HDR software--- the NOW PROVEN HDR lighting concepts have spawned a significant HDR business (i.e. Dosch, etc.) and the QUALITY of commercial HDR's are WAY BETTER now.

Sort of like Poser P4 Free Stuff- compared to the kinds of commercial 3D models made now. (Still usable, but a big quality difference. You basically get what you pay for...)
