This is a ReShade preset that can be used with Anomaly if so desired.
While this preset could probably use a bit more work I am uploading it here in case anyone would like to use it or maybe even improve upon it.
Directions: Extract the bin folder to your main Anomaly directory. Graphical settings (both game and preset) may have to be adjusted to get a desired brightness/darkness.
Edit: Slightly adjusted the HDR effect to not have such a washed out appearance in certain areas.
