If you post your code, I can be more helpful, but I'd like to remind you that
scattering media has an absorption component controlled by the 'extinction'
keyword - I don't know if the black spots you are referring to are areas where
the media absorbed some of the light coming toward the camera or not.

Alternatively, Tim's recommendation of the clear-but-shiny motes would also be a
good way.
