Cinematic Effects in Source
Day of Defeat: Source - arguably the best multiplayer World War II shooter around - builds a cinematic gaming experience with the help of the Source Engine's High Dynamic Range Rendering capabilities. It was the first game released by Valve that showcased their HDR technologies after the delays to the free technology demo level known as Lost Coast. However, the current problem with Day of Defeat: Source is that the quality of the scenes rendered is far beyond what was capable in the time period where the game is set.

Valve are working hard towards making the Day of Defeat experience even more cinematic with realistic effects that you would expect to see in a film of that era. Content development has come a long way in the last eighteen months or so, with the launch of several high-profile games making use of High Dynamic Range lighting.

HDR makes the games look much more realistic. I can't believe that someone hadn't used the technique before!
