A setup to measure light scattering in a glass cylinder. I'm trying to find
a balance between realistic brighness variations in the scene, being able to
view the image on a monitor in 'normal' lighting conditions, and having no
more than a few saturated pixels.

This is the best I managed to do. You'll need a reasonably dark room and a
dark screen background to see all details.

http://www.euronet.nl/~bmeijer/gallery/photons_at_work/index.html shows the
same scene with the ceiling lights switched on and gives some more
information.
