Okay, I did it... went from 1 hr to 11 hrs. It's barely noticeable, but
that's what was suggested. Should I make the effect more obvious? I used
dispersion 1.01... disp_nelems 40

It looks better. I would mistake this for a photograph. Even after a closer
inspection, I'm not quite sure...

Perhaps just a bit more obvious (to justify the 11 hrs :) but definitely not
much. It's a fine image, and fine images are often so easy to ruin...

In MegaPov, to enable dispersion for photons, you NEED to specify a
color_map in the light_source.  There's a macro in one of the MP demo files
that you can use to aid in creating the spectrum.  I think the demo file is
called prism.pov.

Thanks Nathan.. I was wondering why the photons weren't being affected by
the dispersion.

I shall re-render.

It is in colour Jim. As I add in the dispersion, colour is emerging, but I
don't wanna overdo it.

All the best,
