Thanks. The proximity on the building is very subtle but still there. I 
found out that on these kind of objects, it is rather difficult to find a 
satisfying range. It is much easier with irregular objects like the statue.

Hehe. That will depend on what is still to come... :-)

It seems a partial portrait of an ideal world.
I wish could live inside.

Yes ... very nice. I've learned alot about depth queue's from your work. I 
like how the sidewalk pulls the viewer into the scene!

Hmm it looks bright to be too. Funny thing is it seems to look
better to me when applying the inverse gamma correction of 0.45,
so I wonder if there is any way the correction is applied twice.

As far as I understand it, jpeg does not support gamma information
and contains the gamma corrected RGB values for your display gamma.
Can you post the unprocessed png output from POV for comparison?

I too have noticed this about your images, Thomas. I have come to think of it as
an aspect of your image style, your POV 'personality' as it were!

It usually looks as if your fog distance is a little small. However, juggling
fog distance to minimise washout and get the best depth cues (and/or sky
gradient) is not easy. I've got it wrong before - in an effort to get a hazy
atmosphere I think I overly washed out my chess-based RTC image from a while
back. (My main problem is that my laptop screen is damaged, so brightness is
uneven across its surface, and, coupled with the usual viewing-angle variations,
makes it difficult for me to judge image brightness.)

The png would be too large (>1 Mb) to post here.

What I wonder about: How do you see the immediate foreground? Too bright? 
Normal? Because it may just be my fog used that is the cause.

The fog distance may certainly be a bit too small, especially when looking 
at the inside of the building. However, I do not feel that as a problem and 
rather welcome the wash out there, so maybe this is about differences of 
perception between observers :-)

My principal test when considering fog is how crisp the foreground is 
compared to the background or the middle ground. I must admit too that media 
works better than fog of course, but I do not always opt for that solution.

I post here a cropped part of the image.
