Firstly, bring up the cheat console by pressing CTL + Shift + C at the same time. Then you can enter any of the following codes for the corresponding effect:
The following cheats require you to have post processing on, so enter this code in the cheat console first:
boolProp enablePostProcessing true
(when you have finished, just enter: boolProp enablePostProcessing false)
bloom rgb (0.0 to 1.0) Create an effect using different clours. Instead of typing 'rgb', you need to enter three values, one representing r(red), one for g (green), and one for b(blue). These values can be any number from 0-255
filmGrain (0.0 to 1.0) Created a grainy effect on the screen
letterBox (0.0 to 0.4) Adds a letterbox effect to the view.
slowMotion (0 to 8, 0 is normal) Effects the game speed.
vignette (centerx centery X) Makes the middle look clear but the outside edges of the screen blurry (a vignette effect )
Just enter 'exit' to close the cheat console. You can also enter 'expand' or 'contract' to make the cheat console bigger or smaller. You can also enter 'help -all' to get a list of all cheats!
It's probably obvious, but for the stuff in brackets just write something that fits! So for example if you want to use the slow motion effect, just enter something like: slowMotion 5.
