As I see that you take the time to answer to many people here, I was
wondering if you could take some time to teach your knowledge ?
I know that your website is already a gold mine of informations but I would
like to know how you work :
- do you use the GNU/Linux version of POV with a bunch of scripts or the
Windows version ?
- do you create each object of a scene seperately ?
- do you make a lot of render or do you work "blinded" ?
- ...
All that kind of question. Like a master to the followers that we are.
Thanks

Of course!

I use the Linux version, usually just from an xterm. The only script
I use is to shorten the name, so I can type "pov scene". I use
WindowMaker as graphic window manager, ROX filer as file manager and
gvim as text editor. My usual work flow is to open a ROX window with the
scene folder, double click on the scene, type into gvim, then use
alt-tab to change to xterm where I type the command line or use the
upper arrow to recover last call. For me it's a very simple but fast
work cycle.

Hmmm... not as often as I must... I mostly use partial rendering to
model the object "in place", but I can hardly recommend it over the
separate scene, which is a much more serious approach.

Can I say "both"? :) Although I get what I expected most of the
times, I still need to do a lot of test renders.
Thanks for compliments, Christophe.

I meant in more general sense than just the examples I provided. But as
I said I don't know how they were made. You just wanted to see images
showing wide dynamic range in single photo. But did you mean that you
want to see an _unmanipulated_ (no composites, no selective brightening
etc.) photograph showing wide dynamic range?
Back to Jamie's image:
First of all you don't know if the things outside are sunlit or in the
shadow - I think they are not and can't be. Second, you don't know how
bright the lamps are supposed to be. So basically you can't say anything
about the ratio of those two lighting conditions and thus how they
should look in a real photograph (what ever that means...)
It is hard to find photos showing wide brightness range with traditional
films using Google but when I make one I try to scan it and post
somewhere. Most of the pics in net are made with digital P&S cameras
which have a very short dynamic range. Nothing compared to traditional
B&W film - allthough digital SLRs are getting better all the time. But
if one wants to imitate a cheapo digicam, then the highlights should be
blown out...

But the above picture had possibly no lights inside, Jaime's picture
has. But ok, it was a bad example and I can't find now any better. You
just have to believe me :)

Thanks for the answers Jaime.
I'm goin to try the ROX filer and Gvim.
I used to use vim and console only and sometimes QT-PovEditor.
It's seems that the way you work is not as sharp as I thought but
apparently, you have a better control on the result than me (and probably
most of us).
I always need to render a lot of time to get a result not too far from what
I wanted.

Woah!
There's a huge amount of stuff in this scene, and it's all incredibly realistic.
But... it still doesn't look real. There's a few things that stand out to me as
being wrong, though I don't know if that's what creates the overall effect of
un-realism, but in any case I'll list the things I've noticed:
A lot of the materials look perfectly smooth - the walls, the ceiling tiles and
metal strips between them, the blue-grey colour on the desks. These are all
things which would usually have some measure of bumpiness and/or imperfection.
Google found a good photo of ceiling tiles:
http://www.sachem.k12.ny.us/building_construction/Chippewa%20pictures/P1200047.JPG
The highlight on the table in the foreground looks like a simple specular
highlight which seems out of place in such a realistic scene, and inconsistent
with the sharp reflections in the desk surface (i.e. shiny surfaces have small
highlights). Maybe, if you want photorealism, try some blurred reflections.
Some other material suggestions: The screwed up paper & post-its look wrong -
probably needs sub surface scattering, the chairs look a bit hard - maybe an
anisotropic fur material would help?, the beige plastic on the PCs isn't quite
shiny enough, and the wood on the desks and shelves doesn't look like anything
I've seen on such furniture but it looks pretty realistic.
The whole office is incredibly clean, no ash in the ashtray, no coffee marks in
the mug or rings on the table, no scuff marks on the floor, water stains round
the plant pot, dust, and all the desks seem perfectly aligned. None of that is
impossible, just very unlikely.
...and that's everything I can see that's wrong with it! Personally I think the
lighting looks really good. Plus the modelling details are stunning! I'm very
impressed by the overall sense of clutter, that's incredibly hard to do in a ray
traced scene and you've done it very well. How much thought did you put into the
chair positions? They seem very natural.
Hope that's of some use to you. It really is an awesome image.

That was not planed, as you surely know...

No, everyone is coming late because they know the boss is not going
to be there this morning. :)

Here in Valencia it's more typical to have panels like the ones you
describe, which a have a sort of diffuser grid instead a flat plastic
cover hiding the tubes. But of course the later was much easier to do...
anyhow, you made me try the other kind:
http://www.ignorancia.org/images/personal/office-13.jpg
I tried also to decorate the ceiling panels, but radiosity didn't
like it... all sort of artifacts appeared, so I left them untextured.
I've also increased the sunlight intensity to please Christoph. :)
Thanks for the comments!
