Harmonious and peaceful scene, I like it

Very quiet  and beautiful :)

No smoke? :p
And I won't ask you if you like fried chicken as well? :ppp

Backside diffuse. A box clipped_by another box to open top & bottom and 
leave only the surface.

Thanks!

Some light from the direction of the moon (area_light with all the 
standard bells & whistles, i.e. circular orient adaptive jitter), but 
the main light sources are the candles (again area_lights); the 
illumination of the water below the lanterns is achieved with a greenish 
diffuse plane right below the transparent surface. Radiosity is used, 
but maybe doesn't even play much of a role.

 From my researches, there are several such festivals in different parts 
of the world, though many seem to be using open vessels, or just set the 
candles afloat in the water. The most popular festival using lanterns 
seems to be something in Hawaii (IIRC) - and indeed another annual event 
in Japan, but I'd hesitate to call it a "festival": They're 
commemorating the nuclear bomb attacks, if I gathered it right.

Not bad. In fact, quite a good idea!

My only thought is (without having it seen in reality so just guessing) that 
the water surface close around each lamp should be illuminated by the lamp 
light, even if only a little bit and in the color of the light's color.

And the moon is too blue in the water, I believe.

Well, they do - as can be seen on the closer lamps. The direct 
illumination from the candles inside is a good deal stronger though than 
the indirect one from the colored lanterns, so there's not much of a 
difference. And on the far-away water, specular reflection strongly 
dominates, so we don't see the water being illuminated.

Yes, as far as realism goes, you're certainly right, as I deliberately 
"tuned" the moon to get a stronger contrast with the lanterns' colors.

(Then again, in reality the observer's eyes would probably adapt a good 
deal to the lanterns' colors, causing the impression of a rather blueish 
moon.)

Another thing that's deliberately unrealistic is the moon's size - it's 
about 5 times larger than it would be in reality.

I have to confess I didn't actually recognize it as the moon
before reading your post. Apart from the size and the color,
this may also be because the view is so crisp and I've never
been to a place where the environment gets so dark (and
with full moonshine at that). Maybe add a bit of halo?

Nice image, though.
