So that one could see details in this render, I had to increase the
brightness parameter of the radiosity settings up to 4. Objects that emit
light (Tina's neon, salt-gem lamp, fire, Povotron's screen & LEDs, top
button of lift panel, the media/photon/dispersion experiment ...) have
normal ambient (typ. 1 to 2) or emission value. Therefore, the contrast
with the light outside is artificially too small and unrealistic. I'll try
a render with more realistic settings.

I order to achieve this, I can set normal radiosity brightness, ie 1 or so,
and try to increase the 'sensitivity' of the camera by multiplying the
values of the sun, the diffuse parameter of objects, and the ambient of
light-emitting objects by a given factor (> 1). What do people think about
that?
