Most of the screenshots are taking using a mix of the following:

Copy everything in the fnenb folder located on the downloads page to your Skyrim game folder.

Copy d3d11.dll and decompiler_46e.dll into your Skyrim game folder.

ENB Helper and SSE Parallax Shader Fix (Beta) if you wish for parallax to work as shown in screenshots.

This is my personal take on it though, and while I tried to retain some of the high fantasy/realism achieved in the original mod, it doesn't look the same and I feel is a new preset of it's own. Please go endorse the original mod, I give just about all credit to Fork for getting this preset to this point. The amazing Suki's ENB by TheForkOnTheLeft was my favorite ENB for LE and after attempting and succeeding to get the shaders ported, the author kindly gave me permission to upload the ENB preset here.
