Making saves to Rudy ENB shaders

[malcolmarcher]

Hi, can someone help?  I have recently started modding Skyrim SE. I have successfully installed Rudy ENB SE, which I love. Whilst in game I am able to access the ENB EFFECT shader parameters and make a few tweaks to the lighting levels etc. I cant find out how to save the changes, so I don't need to re-tweak every time I play the game. In the left hand window I am thinking there are two possible options: Either click the box that says ... 'Some changes require reloading (apply button)'  or click the box that says 'save configuration'. I'm not sure what the first option means, but didn't want to click the save config button as not quite sure what configuration refers to. As I said, this is all new to me, so would appreciate some help. Many thanks. Malcolm.

"Save Configuration" saves all your changes to the enblocal.ini, enbseries.ini and perhaps other ini files and Apply Changes instructs ENBSeries to apply the changes you just saved to the current game. In other words, you should make any changes you want. When you are satisfied with the changes, click Save Configuration to persist the changes and click Apply Changes.
