How to write down?
example:
pigment{ color srgb < 0.5, 1, 0.3, 0.7>}?

Yes, I added. :(
But, It is a lot of big windows, unless it shouldn't be lighter in the room?

Further down the line, UberPOV gives me this.

Which reminds me that I still have to make blurred reflections work 
properly with photons.

Does UberPov also support blurred transmission through transparent objects?
If not now, it could be on the to do list.

It /is/ on the to do list ;-)

In Real Life, the eyes adapt themselves to the shadowy parts of a room 
and, without you being aware of it, the lighter parts are then overexposed.

In photography as in ray-tracing, you need to find the balance between 
the two extremes. Adding a light is possible but a feeble solution imho 
and not really convincing. If you really want the shadows cleared more, 
increase recursion_limit to 4 or 5.

Not exactly: should be srgbf or srgbt as there are *four* parameters in 
the vector ;-)

Thanks!

clipka, I noticed that in your work light on a floor in the room differs from
light on a floor in a mirror. It is correct?
