Drag and drop the Reshade Presets into your assettocorsa root folder
It is usually C:\Program Files (x86)\Steam\steamapps\common\assettocorsa

Download & install reshade here: https://reshade.me/
Install reshade on acs.exe and check all boxes when prompted

I recommend using it with either AC Real 2.2 Raw or AC Real Public (Free) PPFilter.
I have included Pure scripts & configs for these specific PPFilters. If you use AC Real Public select the "AC Real - Pure" version.

Dashcam v1.0 is the Reshade I've used in nearly all of my recent videos.
The Clean version is less Jpeg'd/Grainy but still has camera lens effects.
The GoPro version is like the original but with fisheye distortion.
The GoPro Clean version is the same as GoPro but less Jpeg'd/Grainy.
The Driving version is like the original but without lens effects, so it should be easier to drive with,
but this Reshade was mainly made for replays so it may not be the best choice to play with.

NOTE: Some of the Reshades have CinematicDOF enabled, so when you click (left mouse button) some lines/colours may appear.
If this really bothers you simply disable CinematicDOF (or just don't hold left mouse button while driving/recording replays)
