Now the lenses are hidden nomore.
Question for radiosity wizards: this scene took 1h and 45 minutes to render,
so I decided to try with better settings: count 150 pretrace_start 0.08
pretrace_end 0.01 error_bound 0.1 and recursion_limit 2 but the results were
much worse! Many little artifacts, circle shaped... what is wrong? Should I
lower error_bound? Perhaps someone could suggest me some really high
radiosity settings...

Thanks in advance,

recursion_limit 1 should be sufficient here, i would try something like:

radiosity {           
    count 300   
    nearest_count 7       
    error_bound 0.1
    recursion_limit 1         
}

lower error_bound could look good, but you have to use higher count then
too.

Oh, now that's good! I just copy/pasted your settings and, after 2 hours (I
also used a better area_light), I got this one. Any suggestion to make it
closer to *extreme realism*?

Thanks,

I have a pair almost identical to yours (the gripping ridges are rounded
not flat on mine (povspeak: cylinders ending in spheres)), but mine has
a lanyard/neck strap attached to it, doesn't yours? >:-}

Apart from that, the surface of the tubes looks more rubbery dull on
mine, but I know from experience, that that look is hard to get in pov.
