I usually make several states of my work. This time, I revisited my 
entry for the March 2011 Challenge of the TC-RTC:

http://tc-rtc.ideasintoreality.co.uk/imagenewdisplay/stills/index325.html

Some minor changes and additions and a render performed with UberPOV 
(stochastic aa) instead of Megapov in the original. All in all, render 
time was in excess of 48 hours.

In a few years time I probably shall render the next state. ;-)

I like the change in illumination around Cathy. I am not too sure about 
the bloom around the street lamps. The pattern does not reflect the mist 
at ground level.Also, I seem to remember that the bloom was centred just 
in front of the lamp. It has been a long time since I have been out in a 
night like that. :)

The bloom came out a bit stronger than I intended, especially in 
relation to the street media. I had noted this for the future state. :-)

Render time is so long that I postpone any new version to 2020 at least...

How many cores does your CPU have, now? Computer GHz have sort of 
stagnated, and CPUs with more than 6 cores can cost as much as a typical 
PC all by themselves. Also, you may want to wait until mitigations for 
Meltdown and Spectre have made it into new CPU architectures.

Meh.   Wait a little while, and you may get it done faster than you think.

The atmosphere is good. Lighting is usually the most difficult to get right,
especially in scenes like this, with not much light.

Well done Thomas, I could learn a thing or two here.

Cheers
Ton.

Intel i7-2600, 64-bit, 3.40 GHz, 4 cores/8 threads (6 used for the render).

LOL Yes indeed! However, the main reason is that I become tired of the 
scene and want to lay it on the shelf for a while. I am going to print 
this version and hang it on my wall. Time for scrutiny has started now.

Hartelijk dank!

Initially, the most difficult was to backward engineer from the 
photograph. Camera position/orientation, lens characteristics, all that 
is unknown from the start. Invaluable help came from the use of Tim 
Nikias' Glare macros which allow for a background image in the scene. 
That way I could reconstruct more easily perspective and size of the 
different street and building elements.

Lighting and media were/are the next pain in my right foot big toe. I am 
still not done there although I get gradually closer to what I want. 
Patience is the keyword.

Tim Nikias' site can be found here: http://www.nolights.de/index.html
However, I cannot find the Glare macros there anymore. Somebody any 
idea? Tim?
