Hi,

By using "trial-and-error" and all my knowledge about raytracing, I did this
today. A few things will be easy to fix, such as the brightness of the red
color, and the too strong reflection on the white tube-head.

I was surprised that I needed heavy "variable reflection" to get the right
look. Are there any references for real life values?

I used one area_light with strength 1.. Is that wrong, or not important
unless I add other light_sources?

I didn't use fade_power, but I guess that's correct for the sun?

I used focal blur with 30 samples, but the anti-aliasing between red and
grey is not as good as the photo, while the shadows look pretty much the
same.. Do you have any idea why?

Other comments will be welcome!  :o)

Regards,
Hugo
