I believe it is time to reveal the state-of-the-art of my latest work for 
the TC-RTC.

Left, is the original photograph by Sabine Weiss of a night time Paris 
street in 1951, a period and place I remember well from my youth. Right, is 
my reconstruction so far, mostly meshes built in Silo. POV-Ray 3.7 RC3 as 
scene builder and renderer.

I made a quotation to another of Weiss's prints which I leave you to 
discover yourselves ;-)  (Google is my friend)

This represents about two months work so far, with still a lot of details to 
fill in, not in the least the electricity cables.

What is your impression?

Thomas

1950's Paris.

Except, shouldn't Kathy be dressed more as a ragamuffin?

I look forward to seeing the final render with atmosphere. It makes me 
want to use/steal the print for my darkroom scene. ;-)

Yes, that was what I was hoping.

Point is: I want to suggest a time mix. In b/w is the period Paris of 1951, 
while in color Cathy lives in a much later dimension, unaware of her 
surroundings. Not really convincing maybe, but that is the idea.

The atmosphere is already there, but difficult to fine tune. There is a 
subtle scattering media beneath the street lamps which needs to be thickened 
a bit probably.

You could try making the scattering media fill the whole scene as in the  
photograph. If everything disappears and you need more control, try using  
a density_map with 0 density at the camera and high density further away  
(that's what I did in my sunflower scene btw).

Presently, there is a background scattering media, in a separate light 
group, for the night sky, and there is a scattering media in the street 
which, however, does not reach the closest street lamp just behind the 
camera. I did it that way for decreasing render time. I shall experiment 
with your idea and include also the foreground in the media. The density 
idea seems indeed a good suggestion here. Thanks a lot for that!

Wow ... the hard work you've put into it shows. You've captured the mood 
of the original plus some ... excellent.

Curious (as I've had this problem too) ... why do the right side 
buildings look straight up perfect, but the left side looks almost there 
as well (except with the fence nearest the camera) ... I'm looking at 
where the fence/building meet. I'm sure (well maybe not) this has to do 
camera position and viewing angle. Not being critical of the work, but 
just hoping to start a conversation about the best ways to solve this 
problem ... what's your camera definition look like ... or is some kind 
of transformation of the objects the best way to tackle this.

Oh ... yeah I like the contrasting idea of almost all b/w objects then 
one or two objects in color ... nice touch!

Likely more to do with real camera vs POV camera.  In real cameras lens
distortion effects like barrel distortion get introduced which POV doesn't.  Can
also be a simple perspective issue.  Bringin the camera in closer with a wider
veiwing angle will exagerate perspective more.

pretty damn good so far!

reconstructing scenes from photography is stimulating, isn't it?  And a hell of
a challenge for sure!  Still need some matching up with the right angle, but
after you complete this, seeing it from another angle is a must too.  After all,
this is not merely a 2D register. :)

how did you do the fine details like the fences?  Is it a texture?

cool ... thanks for the "teaching" moment ;-)
