The docs suggest that "intervals 10" is the default value anyway but I shall
play around with the different methods and see what things look like.

Ah, thank you for that, I didn't realise quite how many demo scene files
came with povray! Looking at those has proved very useful, I had the
scattering at rgb <1,1,1> so it was extremely intense. It hadn't occured to
me to reduce this (in the same way as you do with lights) to make it less
intense, I thought that would be a density issue.
