I have this enb
http://skyrim.nexusmods.com/mods/21223

this enb is great except that night time and interior are bright, like what the modder said but i didnt like his approach(it was darker in version 1)

So how could i manually change values to reduce brightness for interior, nighttime and possibly sightly in daytime?
FYI i am using climates of tamriel too so i removed the realistic lighting files from the enb, but there aint much difference anyway
