Hey guys,

This is a shot I recently completely and is the last time I will run it 
because the render time is simply horrendous.  It's a six engine German 
bomber flying at dusk, the sky covered in anti-aircraft flak.  I had two 
computers chewing this and it took days.  With the thousands of media 
objects combined with the glows and motion blurring, the computer almost 
came to a screeching halt.  Anyway, I wanted to have the underside of 
the aircraft bathed in orange light.  To attempt this I placed an area 
light underneath the aircraft but it left behind unwanted effects.  You 
can see the light source in the windscreen when all I wanted was a kind 
of evenly spaced orange glow.  Would MegaPov's/3.5's parallel lights 
accomplish this?  Any comments on the flak or city lighting?

I cannot answer your pertinent questions. 

But looking at your image I get the impression that engines No 2 and 5 
are not directed parallel to what is the flight direction. Do I see that 
wrong??

Plane looks fantastic.  A few comments

City lighting:
If this is a bomber over the UK, I can tell you that we don't have US style
street blocks.  Our roads (especialy in cities) go everywhere.  try
www.multimap.com for a street map of the UK and you will see what I mean.

Flak:
I am not certain about this but should there really be so much flak in the
sky.  All the films (not always accurate I agree) I have seen seem to have
less.

Other comments:
Is this a lone bomber (perhaps the last one left in a mission - in which
case should there be some damage to the survivor).  Otherwise, where is the
rest of the squadron.

The engines look like they are at different angles because this is a
wide angle shot.  The camera angle is very high.  I wanted to the 
airplane
to fill the shot but have the entire wingspan visible at the same time.
    I did some research on the flak.  There were varying amounts of flak 
and
I believe in many situations there was even more flak then what I 
rendered.
Pilots described, "seas of flak," and I saw a couple pictures showing 
this
as well.
    Yes the city lights are unrealistic.  I know many cities turned 
their
lights to avoid becoming targets.  In London they dimmed the downtown 
area
and lit up the docks on the eastern side real bright trying to divert
attention from the city and confuse the enemy bombers.  I did square 
blocks
because they looked more dramatic and fit better with the wide camera 
angle.  I thought a lone bomber would be more dramatic as well.

Your image seems tasteless considering what happened a few
days ago.

That is one strange image.  I think you have done some daring and
original things with it but it is just missing somehow.  I think the
regular grid of lights, while adding to the strangeness and synthetic
quality, destroys the sense of space just too much.  This is already
challenged by the way the plane floats just under the horizon, its color
matching the sky, together with its symmetric relation to the picture
frame. That effect is very interesting as it compacts a lot of
information along the horizon line.  But the light grid destroys the
delicate effect for me.  Can't help but wonder how just a few lights
below would work.  I would suggest you work with copies of the image in
a graphics editor and try some different things.
