Looks more interesting at larger sizes... contrast is artificially boosted...

"Artificially"? That implies that there's something natural about it.

Heh.

Well, in the sense that all the processing steps before the contrast boost are intended to be at least crude approximations of real physical processes (e.g. the material used is a "cook-torrance" model, which is based on a statistical model of certain types of physical surfaces); the source of light is an HDR image of a real location, which nominally (though who knows in reality) has a linear relationship with the actual light levels there.

The contrast adjustment step, on the other hand, is just an arbitrary curve based on what looks cool...

[Of course photography is rife with such arbitrary transformations... :-]

well done i really lige it.
what rendering engine are you using because mine do not support cook-torrance shader model?

a personal renderer?
based on what ... is it unbiased?
I really like the indigorenderer (indigorenderer.com)
do you plan to release it someday or is it just for research/education or fun?

The renderer tries to be unbiased, but of course, given bugs, who knows...

As for releasing, who knows; we all have dreams, but basically it's for fun. Honestly speaking, the only thing I can offer that existing renderers don't do much better and faster is lots of crappy code! :-)
