This is a large collection of screenshots, meant to aid you in chosing the right ENB for you without having to do all the copious testing work that I've just done.

All the screenshots you see are done on top of Lexy's Legacy of the Dragonborn guide (Changelog version: 10th April, 2020), including all her ini file settings (initially for Ljoss).
Adjustments I have made: Textures for Hold Banners and Shrines.

I have not fiddled with any in-game settings (such as brightness, it's smack in the middle), and I left all the ENBs on their default settings, too.
Except one - because I wanted to try and then forgot to set it back to default. Shame on me.
This is The Truth ENB, and I only enableld and adjusted the DOF, so colors/lighting/etc. are still out of the box.

ENB version used is either 4.15, or 4.17 - I updated halfway through, because when I went to download Silent Horizons - well, the newest version required it. Since my screenshots don't show any shiny wet surfaces, I don't think the ones with 4.15 are at any disadvantage though.

File names correspond to my save game and the used ENB preset, so they appear ordered by save game.

If you're a nerd like me, and want to decide what preset to use with semi-scientific methods, I have prepared a spreadsheet for you to enter your rating for all the screenshots. It will rank them according to your average rating. (Beware: this is harder than you think! :D)
This spreadsheet is also available as a google sheet, for you to make your own copy!
