Had your chance to play the Lost Coast expansion map for HL2 yet?
That map really does show what HDR brings to the table, & I can
tell you, it’s pretty cool. Varun over at CTZ explains what HDR is all about:
“In simpler terms, HDR allows you make the
objects brighter by allowing them to use the full brightness
capabilities of the monitor and not just the brightness level at which
they have been shot with (or rendered with) in the scene.”
