It doesn't work that way silly!
For those of us who don't want overkill bloom and saturated to death colours.
This is a basic preset(cfg) for GEMFX. Its purpose is to deliver enhanced colours, sharpness and all around beauty to the game without making your eyes bleed. This preset uses ambient light to deliver realistic bloom effect where needed and strong colours to rid the world of grey.
* All of your in game settings should be on max to get the full effect. Turn however anti-aliasing off since GEMFX will do that for you. Post-processing is optional, personally I do not use it as it makes immersing harder.
* If you desire more colour, ticking "Curves" under the SweetFX tab should do the trick. Make sure your Curves is set to 1 and not 0. You can change that under the Curves tab in the configurator.
* Should you find that it is indeed too much bloom just turn off ambien light, ambient is what causes the game to glow at certain points to create natural light.
(If you can not see the captcha it's because of addblock. Just turn it off and it'll show, you can turn it back on after!)
