Today's update brings good news - Lost Coast and HDR are coming ever-closer to release. They will be available in VALVe's future product releases, (Day of Defeat: Source) but there's no news on whether they will be integrated into existing games.
According to VALVe, HDR relies on a little something called
Dynamic Tonemapping to simulate a character's eyes more realistically and response to light and dark areas. This effect cannot be captured in screenshots that are static, so VALVe has even included a nice video for us to watch and observe this effect in action in
coast.
Lost Coast and HDR will certainly make a breakthrough in terms of visual quality in the Source engine, and are very impressive as the video demonstrates. We can't wait.
