   I used 50% opacity on the SSLT layer, and perhaps it wasn't enough. On
the last one posted above, I didn't use any transparency on the screened
layer, and it looks a bit better.

   As usual, you're right on all accounts...

   The SSLT layer is of course a dirty trick, but it's worth the little
extra time if you don't have the patience to wait 2 days for the "real
thing". :)  ...as for the color, in fact I rendered he SSLT layer with
"translucency 1", and added later the red tone with The Gimp (this
seemed to give the best results with the "screen" layering mode).

   And yes, the highlights are wrong for "recently collected" oranges
(but they would be not too off for oranges on the market). I guess it's
time to try the new albedo feature... :)

   Thanks!

Or perhaps some kind of scent generator 
(http://en.wikipedia.org/wiki/Digital_scent_technology)? Naa, I prefer 
better the fresh orange sprayed on the postcard... a new kind of business.

I was thinking of this:
http://www.nationalgallery.org.uk/paintings/luis-melendez-still-life-with-oranges-and-walnuts

But maybe you could use bullet physics to make a Valencian paella?

I wonder what POV-Ray version he is using. SSLT is missing... ;-)

Very interesting painter... I never heard of him, but I'm really
ignorant about art and artists.

   :) ...totally weird idea, but feasible to some degree. It would be
difficult to model some of the ingredients realistically enough, if I
want to stick to the official denomination of Valencian Paella.

On a more serious note: One day, I would like to render a copy of this 
painting. Some interesting challenges in terms of modelling amongst others.

A trip to Madrid to go to the Prado is worthwhile IMO.

A Joke! A joke! But if you want to try you would be an alchemist. ;-)

to good effect. But you have to see them in the flesh, so to speak. (I actually
wanted to wipe the bloom off.)

Many a time I have looked at it and other still life then just wandered away
saddened at the mess I know I would make. :-(

The subsurface on the oranges looks much better now, as does the ground texture
and grass blades. I love the idea and implementation of the burned lettering
too. Nicely done, Jaime!

Weird. His finish{} block of the grape is flawed imo, and he used indeed 
Sam's bloom macro.

Not necessarily a mess, Stephen. It would be your own interpretation of 
it. As a kind of citation, in its own right.

I need some time before starting seriously...
