ENB-related question

[Zerosleepless]

Hi guys

Bit of a noob question:

I've been using Realvision ENB for a good while and now i'm kinda bored of it.

Instead of downloading another ENB ,I've decided  to just start tweaking it myself and make it my own.

I'm going for the sepia/weathered effect witch is pretty much achieved (feel free to tell me what needs fixing)

 

 

 

 

But sometimes you see in screenshots a particular color is "popping" and i'd like my red to be more vibrant and stick out.

Also i'd like to know how to augment the depth of field's blurring strength .

Another issue is that i want to make the lights more intense and the shadows darker ,but changing contrast just makes my whole screen darker , and i just want to darken the shadows alone.

As a reference here's the type of effect i'm going for:

 

 

 

 

Honestly i'm just blindly changing values in enbseries.ini and in game but i dunno what i'm doing.

Any advise on what values to change is welcome.

Edit: Also if i succeed in making this , how do i save this preset and share it with y'all?
