-Installation-
Like all other presets ReShade. Download the latest version from https://reshade.me/ (4.3.0). Download all shaders and unpack the preset you need. In the game, press the "Home" button and select a preset.

DefaultPreset-Light   - Only color correction and SMAA are enabled (you can disable it too).

DefaultPreset - Settings that are used in the screenshots. Affects FPS. If the game has dark places and you barely notice objects in the dark, turn off the "LevelsPlus [LevelsPlus.fx]" option.

DefaultPreset 2 Test - Same as "DefaultPreset" but with a different color correction. I can not say that this is suitable for the game.

How to take a screenshot in high resolution. Read information about Hotsampling - https://nohud.fandom.com/wiki/Hotsampling_with_SRWE_/_WBG

For screenshots I would recommend using "CinematicDOF.fx".
