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 ;-)

What is the time left on a render?

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?

Therefore I asked. Means, s - isn't adjustable parameter

no indeed. It is /not/ adjustable.

clipka, may I place your work on i.imgur.com?
I want that the picture was visible on the page our site.
While I placed the link

I'm perfectly sure there is no such difference. It does differ from your 
results, but that's because I adjusted the light source position to 
better match the images produced with other renderers.
