I use the default settings of Lux, I set nothing in lxs.

Sensitivity, exposure and f-stop are settings in the Lux GUI for Linear tonemapping, you've got to make adjustments to get the right light exposure for your render.

I am in big problem, most of my images are made in interior ambient, dungeons are the preference.
With such illumination in photography is used flash lights that will destroy all the desired scene illumination and soul. And if I want to take a photograph without flash light I have to use manual exposure and have no idea how many minutes I have to expose the film.

Stupidity also evolves!
