Good metaphor, although some would say a moon-textured balloon needs to go
between the others :P

The lighting is nice and moody, too, especially near the middle of the image.

I'm not quiet sure if I can enter the image into the actual TC-RTC competition.
First the link to the topic is only the connection about a journey which is a
bit weak.

But a weak link to a topic is not really my problem. Ian has a very constructed
link this round as well IMO. But Normand still has the Earth as a Balloon.

Otherwise there are only three entries so far.

What to do? Suggestions are welcome!

Best regards,
Michael

Without discussing it. Go for it.

Discussing it:
It would be a shame if you did not enter the image as it is so good.
It is a mistake to think that similar images are not wanted. They are, 
it makes comparison easier. If the topic was Balloons everyone would 
have a balloon image.
You have carte blanche to use your imagination.

I think it's plenty good enough for the topic.  If you think it's too 
weak, you can always include an ars... I mean, back story in the 
description.

Infamy, infamy. They have all got it in for me. ;-)

I really love the sun light in the trees. It's wonderful :-)

I tried a rendering with Uberpov today (+am3 +a0.01 +ac0.9 Count 10, as you
suggested somewhere here). In comparison to my first entry the result is not
very convincing.


Best regards,

Sorry for the short delay of now some five years. I was occupied by some 
RL issues a while and frustrated after loosing all codes by a headcrash 
on a very new harddrive. Nearly, I had finished a very nice scene (The 
Lonely Swan) and lost all the code. Later I experienced a very heavy 
work load and at the beginning of this year a very severe disease of the 
lung. Now I bought a new machine and thought that this open issue would 
be a very nice test (core i7 vs. core i9). I rendered the image due to 
Clipkas suggestions with diffuse albedo 0.5,0.4 on all balloons. It has 
an little bit different mood since the colouring of the balloons is more 
visible in the distance. The backside illumination has a severe 
drewback: it doesn't work with the colour Blue.

Enjoy
Michael

Welcome back! I've been otherise hacking at the source code today so 
took a quick look at the related code on seeing your post.

I don't see anything obvious against blue. My guess is it's that the 
blues of your balloons are quite dark. When the code multiplies the dark 
blue value by the backside value*(light * etc) there just isn't much of 
an adder. Dark+dark still ends up pretty dark - more true if your light 
source doesn't have much blue in it; If it's flame colored.

I've played a little with making the backside values larger than they 
'should be' but probably that cheat won't work well with, for example, 
your world map where the bottom looks to be mostly white-ish. Maybe just 
brighten the blues some on balloons with a lot of dark blue <1,1,2>*...?

I like the image. It reminds me of a balloon festival I attended a 
couple times, now 20 years or more ago. Time flies.
