Thanks. What about the brightness? As sayd in my response to Robert this 
*is* one of the aspects I'm quite unsure.

Brightness is tough as it is somewhat of an artistic decision.  For the human
eye, the brightness would be relative to how long one's been in the theatre
..i.e. your pupils widen the longer you are exposed to lower light, allowning
brighter perception of the scene.  The lighting hasn't changed, just the
viewer's perception of it.

You don't want to brighten it up so that is seems unnaturally bright like the
lights are on, but you do want it bright enough to notice the scene while
maintaining the feel of being in the theatre.  Generally, the lighting you have
doesn't look too bad.

If you want to brighten it, make sure you do it while maintain the feel.  The
main lighting on the character will be coming from the screen, so it should
mainly come from that direction, preferably as an area light (this is why for my
scene I created an image based, area light area, to simulate the actual screen
reflected light).  You may have some secondary lighting coming from the theatre
lights (ceilings and walls), but generally these would be low enough that the
have no noticeable effect on the scene as a whole, but only localized bright
spots at their locations.
One other source of light would be from the projector beam (this is the next
light I am going to add to my scene when I get back to it): the dust in the air
would tend to scatter it a little.  This would be minor compared to the screen
lighting, but could still have some general ambient effects on the scene, for
example some possible minor lighting around the projector window, and minor
directional area lighting on the chracter and seats.  I would probably keep this
to 10% or less of the screen relative brightness, as you don't want it to
overpower and be directly noticeable and competing with the main lighting, but
just add subtle ambience and complement the main lighting.

Overall good work.  Nice to see another POVer getting involved in th 'big boy'
challenges to show em what we can do!  Hopefully I can pull away from my other
sidetracking here at some point to get back to my scene a little more.  One
difficulty I have with this type of scene is texturing, as I like to try to make
things realistic looking, but we are dealing with a cartoon-type character.

I think the overall brightness probably shouldn't be too much more or 
the theater atmosphere is lost ... localized lighting around the 
character looks good but the stuff that's lost in the shadows towards 
the background has a slightly flat appearance ... nearest_count tweak 
with the radiosity maybe ... I'm for sure not a guru in that aspect

I like what you're trying to do.
One thing I've heard is that to portray people at night/ in the dark, use very
high contrast, rather than making everything 50% black.  Maybe that would help
your effect here.

Projector looks very realistic to me - unfortunately that generates a 
stark contrast to the cartoon-esque character.

I'd personally prefer more "comfy" seat textile (if you know what I 
mean), though I'm not sure how to achieve that look.

I was going to be trying a simple 'quilted' normal on mine.  A velvety texture
could be acheived using an aoi pattern perhaps.

I guess this isn't something I'll be saying often, but: Maybe try some 
gamma tweaking to increase the brightness contrast between lights and 
shadows.

Perception of relative brightness levels changes with ambient viewing 
conditions; those in a movie theater are quite extreme (the eye 
typically adapting to the bright light of the screen, causing shadows to 
appear even darker), so some deal of gamma adjustment seems justified to 
me in this case.

Actually I'm using just 2 light sources: the projector lamp itself (with 
some really high intensity: rgb 125000) and a quite dim one within the 
projector cabin.
The scene illumination relies completely on GI and comes almost 
completely (there might be some minor radiosity-media interaction from 
the light-beam with the 'dust') from the screen where I did *not* use an 
image_map but instead the light from the projector is projected_through 
a small image with filter value set to 1 and located within the 
projector - kinda like the real thing.
The only *fake* is the skin of the kid that has its own light_group with 
a few reddish colored lights (kinda SSLT fake) to get a skin tone that 
does not look too natural but also does not look like plastic - to make 
it work with his cartoonish style.
But this is not so much *fake* at all because I'm pretty sure when such 
a shot is done for a *real* movie they would at additional spots and 
reflectors - lots of them ;)

Well, perhaps this volume light from the "dust in the air" is quite a 

still used because it simply helps in making this movie theater flair?
Yesterday I did see "Unknown Identity" in the theater and did actually 
watch out for the beam - but it was too faint to be visible.

Hum, well, hopefully we do not make our favorite render engine look too 
bad among all this Maya, Mudbox and what not 'big boys' tools...

And I do prefer more 'comfy' seats in the theater ;)  ...but I think 
this kind of cushion works well with the orange color that I do need for 
the 70ies flashback.

I just looked through all the WIP renders in the challenge forum and your WIP
from last week with the full 1970s theater, ceiling lights with media, and
projected credits on-screen jumped right out at me as being a cut above; really
nice work! And the POV-Ray 3.7 RC3 blurb, nice!
