Step 1 :
Open the ENB Configuration menu by pressing [Shift] + [Enter], and look at the enbseries.ini panel.

Step 2 :

If that's not enough, expand the EFFECT section, then disable AmbientOcclusion and/or other effects as desired.
In case you forget, the effects I've toggled on by default are:

In the enbseries.ini panel, the COLORCORRECTION section has settings for Brightness and GammaCurve.
In the Shader parameters panel, the ENBEFFECT.FX section has settings for Brightness, Saturation, Contrast, and an Interiors sub-section.

Once your calibration is satisfactory, click the ---SAVE CONFIGURATION--- button at the top of the ENBSeries panel.

If your vision powers are not working with this ENB by default, follow the following steps to fix it.

Open the ENB Configuration menu by pressing [Shift] + [Enter].
In the Shader Parameters panel, expand the CONSTANTS section.
Observe that the following two settings change when vision powers are activated or deactivated:
enbeffect.fx:: Params01[4].w
enbeffect.fx:: Params01[5].w

In the same panel, expand the ENBEFFECT.FX section.
Set the following four settings to ensure that the following conditions are all met only while your vision power is active:
Params01[4].w > VALUE must be lower than enbeffect.fx:: Params01[4].w.
Params01[4].w < VALUE must be higher than enbeffect.fx:: Params01[4].w.
Params01[5].w > VALUE*0.1 must be lower than enbeffect.fx:: Params01[5].w * 10.
Params01[5].w < VALUE*0.1 must be higher than enbeffect.fx:: Params01[5].w * 10.

Lucid ENB is designed for use with Cathedral Weathers & Seasons, but other weathers are technically compatible for varied results.
