Another scene that I dug out from the archive and which I'm trying to 
update now. Most work went into the planet. Slowly I'm learning how to 
put texture maps to good use.

Also trying to make use of the "greebles" idea that Thomas de Groot 
pointed me to. In this case a very simple approach using a bump map with 
some rectangular, elevated patches.

Very good looking indeed.

Yes, a bump_map is quite satisfying in this context.

Great!

It shows a lot of work in the patterns. I believe more radiosity, with linear
workflow and some gamma added to bring  it back to 2.2 could greatly benefit to
this scene by revealing that detail in the shadows.

Another update, mostly fine tuning of object positions and lighting.

Yes, I also think it's better in every aspect... The closest reactors flame was
of a nice color but its shape was too geometric, best to see the contrasted nose
of modules... I keep looking at the picture and of course see new details to
pick:
The furthest planet (rocky one on the left, don't you think it's pattern is too
regular?  I haven't used it much yet, but I would try the warp feature of
pattern modifiers, to give it a more cahotic look... And about the lighting
again, its too strong and flat: I think considering an ini file or command line
launch with display_gamma of around 2.2 or 2.5, if you just put all colors in
srgb and assumed_gamma 1.0 at start of globals (only the output image file
should be put back to 2.2 in gimp or whatever, after render if the final viewing
app shows it bad... But png probably wouldn't) Here is some tips for adapting
old scenes to new gamma maybe you've seen it already:
http://wiki.povray.org/content/HowTo:Migrate_old_scenes_to_work_with_the_new_gamma_system


This will allow you to use and actually take enourmous advantage in such a
scene, of inverse power law (new in POV3.8 and the most realistic), for every
light :
fade_distance 0
(requires  #version 3.8 directive at very top of the file)
Attenuation for the lights is never linear in reality and thus you can choose to
 dim those main light with more control maybe lower or more focused angle,
letting radiosity kick in, especially if you put the deep space tone the darkest
kind of blue you can get instead of pure black. you'd get a less dark shadow but
still bigger contrasts inside of these penumbras > richer tones used overall.

I really enjoy the atmosphere of planet on the right.
And now I see the whole tree populated area inside of the donut, lot of work,
it's awesome! This would also show better if environment light outside the ship
gets lower! please please ! try it :-) One last detail, as much as i love the
crossing streaks of background white stars, having them smaller would do them
good. (The color values can go higher than 1.)

Thanks. I didn't know of these changes. I've tried to convert the scene, 
but there are some problems cause it uses files that are shared with 
other scenes and I need to figure out a way to specify colors that will 
work well in pre-3.7 scenes and also 3.8 scenes (maybe the srgb keyword 
does, but I still will have to adjust the colors)

Seems there is some work waiting for me to update all the files. But 
more realistic output is something I was looking for since a while. So 
thanks again!

Implementing all suggestions will take some time. Not something I can do 
in one evening. But I found some mistakes in ambient settings and some 
more. Don't want to clog this server with data, so here's the link to 
the version after the fixes.

Thanks again! Wouldn't have spotted the problems without your 
suggestions. Can't change the moon and stars easily, but I heard your 
suggestions and I'm looking into solutions.

It was already a pretty cool image anyway. Thanks for sharing

Took quite some adjustments to light brightness and also some colors, 
The result looks much more natural though. I think the gamma problem was 
what made many of my scenes look strange somehow.

Maybe not the final version, but to show the difference I've attached 
the version with assumed_gamma 1.0, file and display gamma 2.2

But it looked very bland with those settings so I used the color-curve 
tool in GIMP to enhance the contrast.

I really like the colors of the whole composition.
