There is a lot that goes into deciding what settings to use with your ENB, but there are some presets available for you to start with, that you can then tweak to your own preferences. Make sure to read the description to make sure that your computer can handle it, that it is compatible with your weather/lighting mods, and how to make further adjustments.

I plan on expanding on this section, with specific examples of ENBs, but here are some to start us off. I believe these were all taken with Rudy ENB for Cathedral Weathers.
Please remember to endorse any mods you download and like, and if you appreciate all the hard work that goes into creating a mod, consider giving kudos to the author on Nexus as well (the Give Kudos button can be found on the user’s page).
