L4D1 Beta Video-Styled No Mercy Color Correction

For any of those who have ever watched some of the videos on the internet containing pre-release footage of the L4D1 beta, you'd notice that beta No Mercy seemed to have this nice high-contrast effect, which put a lot more emphasis on the dark and/or illuminated areas. This effect was mostly caused by the ♥♥♥♥♥♥ camera equipment people used to record pre-relase gameplay, but I really loved the effect, so I decided to try and simulate it using color correction. While it doesn't look exactly like it does in the beta gameplay videos, I'm pleased with the result.
(The actual beta No Mercy maps did not have a high-contrast effect, the reason why videos of it did, is because of bad camera equipment)

This will naturally conflict with any other mods that change the color correction of No Mercy, like Dethly's "HD air" color correction mod.

Also, sorry for the black bars at the top+bottom of all the screenshots, I had the game in windowed mode, and I didn't think it'd screw with the screenshots.
