Hi there,

here is a first WIP from my roman glasses project. At the moment it is in a way
in a laboratory environment. A single light source and a HDRI lighting with
Jaimes kitchen. Next idea is to put the object in a mere natural environment to
see what it looks there. At the moment I think it's a first approximation to the
topic but I'm not really content. Suggestions for improvements are very welcome.
At the moment I use two granite media (one scattering and the same absorbing)
and likewise two agate-media.

Best regards,
Michael

moderate DOF is great for small scale objects, plus it provides good
anti-aliasing:  without it, those edges are terribly sharp... :p

Thanks for your answer, but I'm only a statistician. What does DOF mean? I think
it is not "degrees of freedom".

Best regards,
Michael

I guess depth of field.

Did you use interpolation with the image map?  It looks awfully pixelated.

May be,
but I most liked to have a comment to my picture.
Best regards,
Michael

"Depth of field," or focal blur in POV-Ray terms, makes the most sense in this
context.  A larger aperture makes the scene appear smaller; houses and cars can
be made to look like toy miniatures with a large enough aperture.  With no focal
blur at all, the aperture is infinitely small.

P.S. The human eye has a maximum aperture of 7 mm in dim lighting, reducing to
about 5 mm as you get older.  It is smaller in bright lighting.  You can use
this factoid to give the impression of scale in your scenes.

Hm, I'm a little bit puzzled. There is no focal blur in this scene. It's just a
first WIP for old roman glasses, buried two thousand years in the ground.

Best regards,
Michael

Okay, I like the modelling very much. Although I would say that it is in 

It looks repro, more 16th Cent. to my eyes. It is far too perfect and 
the handle looks wrong too fluted.
But I like it and would like to see more WIPs.
What is the max_trace_level and how long did it take to render?
