Have you tried SweetFX already ?

SweetFX allows you to inject a suite of post processing effects into any DX9, 10, or 11 game (32 bit only). E.g. SweetFX is a universal image improvement and tweaking mod, that works with almost any 32bit DirectX 9, 10 or 11 game or application. It is completely and easily configurable via text file. SweetFX is a mod built on the InjectSMAA shader injector, that allows you to apply a suite of post processing shader effects to your games. Some amazing results can be achieved with this mod.

With this tools, players can add to their games SMAA, LumaSharpen (Sharpens the image, making details easier to see), Bloom (Makes strong lights bleed their light into their surroundings), a fake HDR effect that mimics an HDR look, Technicolor (Makes the image look like it was processed using a three-strip Technicolor process), Tonemap (Light and color adjustments), Vibrance (Intelligently saturates (or desaturates if you use negative values) the pixels depending on their original saturation), Sepia, Vignette and Dither (Dithers the image making it look like it was displayed on a monitor with more colors than actually present).

SweetFX Shader Suite works with all 32bit DirectX 9 , 10 and 11 games (and many applications). Sounds awesome, right? Well unfortunately the mod does not work with 64bit game executables, meaning that gamers will have to use the 32bit version of their games.
