From what I read in the links you gave me, it seems that HDR is an image
format that lets you store non-clipped color values. (normal images cover
RGB values 0-255 (really 0.0 - 1.0), whereas HDR lets you cover 0.0 to
infinity... or maybe even negative infinity to infinity, I'm not sure.)

So you couldn't get an HDR image from a single photograph, since all that
photograph contains is values from 0 to 1, and you need more photographs
with different exposure times to get more information.

That's about all I can figure out.
