Disable post-processing effects (bloom/glare/lens flare)

There's no option for this in the graphics settings and the effect is quite overstated in some levels.
It even affects the reticle in most weapon sights.
Would be good to have a way to tone it down, or even better, switch it off completely.
EDIT: Thanks James, beat me to it! Didn't refresh before posting.
I discovered that it's possible to achieve this by editing PAYDAY 3's Unreal 4 config files.
Not sure whether it's possible to turn it into a mod, but for a manual solution:
Open up
%LOCALAPPDATA%\PAYDAY3\Saved\Config\WinGDK\Engine.ini
or%LOCALAPPDATA%\PAYDAY3\Saved\Config\WindowsNoEditor\Engine.ini
(depending on platform).At the bottom of the file, add the following:
[SystemSettings] ;Disable bloom r.BloomQuality=0 ;Disable lens flare r.LensFlareQuality=0 ;Disable blur r.FastBlurThreshold=0 r.BlurGBuffer=0 r.MotionBlurQuality=0 ;Disable chromatic aberration r.SceneColorFringeQuality=0
Save the file, and launch the game.
