Do u guys think that this picture could really
benefit from the photon map patch ?

This is the modelisation of an experiment
to retrieve carbon dioxyde from a baking
powder's alcoholic fermentation.

That's a really nice image! As bright as it is I'm not sure what photons
could do for you, but I'd throw them at it anyway! :)

This is great stuff. I indeed think it *could* help, especially if you
can get a mild sort of spectral dispersion in there, you know, by adding
a averaging color_map to the light along with the regular light color
syntax.
The liquid in the tank goes almost unnoticed, and knowing how fish tanks
split light this would be good to show it's existence better maybe. That
upside down "graduate" threw me a curve to begin with as it d/l'ed. The
flask contents don't appear to filter light at all, and I'm not so sure
about the photon mapping doing good rather than harm to the rest. I
haven't had much luck getting subtle caustics yet.

The caustics in my image (post: "My first real photon map image") are fairly
subtle although I don't know what caused this effect, I used an area light
and I've heard that UvPov has some problems with area lights so maybe that's
how the caustics got so subtle?

I think UVPOV simply treats the area_light as a point light. So this
shouldn't be the problem. But you could simply test this by using a point
light. Have you tried it?
Of course, caustics is (esp. those of a seal ;) are a bit difficult to
predict. Maybe the majority of the light is concentrated somewhere out of
the camera's view.
