   Yes, thanks... I was trying to follow your latest advice on focal blur,
but screwed it. Now I think I got it right (see my last post).

   No, I was over-using the specular there... now I raised it by half the
amount. Thanks...

   You're right about the ground... I abused the specular, and also used a
too simple normal on the ground height_field. On the last shot I tried to
correct both, thanks!

As usual, another top-notch rendering. You're truly a master at POV!

That looks much better! It's an awesome scene :) Did you try out the ground fog
version I posted? It doesn't look nearly as good, but I wanted to provide the
option for it anyway.

Media would be the ideal choice in any case, but it's still pretty slow even
with multiple cores.

In other scenarios, casting glare from the sun would also help balance the
light. A sphere with a polar or spherical pigment pointing at the sun works. And
there's that clear tube with a specular or phong finish connecting between the
sun and camera. It seems to work pretty well, and even reacts when something
occludes the light.

And then there are clouds. The same technique of using a polar pigment located
at the camera position--and pointed at a light_source--can help "stacked planes"
clouds look more realistic.

P.S. Are coral snakes desert creatures? I heard this saying regarding the
distinction between coral and king snakes: "Red touching yellow, kill a fellow.
Red touching black, friend to Jack."

Looks beautiful. (I really like desert scenes--they can incorporate lots of
random-looking detail that help 'sell' the image; and you've done a really nice
job with that.) The depth-of-field looks better in this one too. But I miss the
tiny circling birds. :-(  Or maybe they're just washed out in the sun glare.

Methinks the scene could use a bit more ambient lighting in the shadows now (or
brighter radiosity) since the sky now has some atmospheric glow. Seems that it
should fill in the shadows more.

I like the scene!

Any chance of all or some of the scene code being posted somewhere?

I would love to use the desert/rocks to help create a Lego Stars Wars 
Clone Wars desert battle scene similar to the image found here:
http://alj029.blogspot.com/2010/03/almost-there.html

I already have Lego 3D models of the Imperial Dropship and the 
stormtroopers (see link below for picture of the dropship)

Bye for now

  Yes, there are chances... but who knows when? :)

  Seriously, I should finish this scene, clean and publish the code, and 
answer some pending posts on this thread... I'm almost finished with the 
thing that was eating all my little free time, so perhaps I can do it 
soon. 

  Anyhow I can send you the code "as it is" now, if you really need it...
