I think this mod is great, thanks for bringing it to our attention

. Whilst this effect may not be 100% realistic, I think what bloom does well is take the cartoony edge off the graphics, the changing contrast really helps, kind of like basic HDR. Also it does a good job of simulating atmospheric hazing.
Dunno if its been mentioned already but this also works very well in LockOn and IL2(if you use DX renderer not OpenGL). I still have to try it in CNC Generals
Hey, heres a funny thing. Over at the Lockon Forums they also have a "Bloom" thread going, its scarily similar to this one

. Hell, they even have their own Tristan
