Yes folks, it's time for Yet Another Reflective Sphere On Checkered Plane!
This is a WIP for the Before+After round of the
I-can't-believe-it's-not-the-IRTC contest. The concept here is rather
obviously before + after I got my mad povray skillz. I'm gonna have a
double-image with one side being the standard rsocp like I could do when I
first used pov, and the other side being the most realistic rsocp I can do.
This is, obviously, the latter.
There's some tone-mapping in there already though I think it looks a little
like a painting not a photo at the moment. So I'm gonna mess with that and
add some lens effects (blur, dispersion). BTW, if it isn't obvious, the
background's another HDR probe from http://unparent.com/
Any suggestions on how I can make this more real?

Looks great! Very impressive.
If you're using HDRI, I'm surprised that the shadow is so sharp. Are you
using a light source as well? If you are, you might consider making it an
area light.
For my own taste, I would either move the camera a little closer or make the
sphere bigger. But that's just my own opinion.
I'm curious what you mean by "tone-mapping"--I've not heard of that before.

Uh, pretty nice! Pretty damn nice to be specific :)
As you ask for possible improvements: Personally I don't like seeing the
background where the table ends, I'd prefer some sort of ground. As a
minor thing I'd suggest adding a frame around the chessboard, I've never
seen one where the tiles start right at the edges.

Florian

Yeah it's a light source, with radiosity for the HDR. I was suffering nasty
artefacts with just radiosity and HDRI (hence my earlier HDR post using a
light dome) but evidently having 1 dominant light is enough to make the
radiosity look good.
You're right, it needs to be an area_light, I'll go fix that. I'll also
stick in a shadow from the trees.
Tone mapping is like a gamma curve but fancier, see the megapov
documentation on it's tone_mapping feature:

Thanks! Came up with that moments before posting
pigment {
crackle
form <1,-.5,0>
pigment_map {
[.2
crackle
solid
colour_map {
[.25 rgb 1]
[.25 rgb <.8,.7,.5>]
[.75 rgb <.15,.1,.15>]
[.75 rgb <0,.05,.05>]
}
]
[.4 rgb <.2,.1,.07>]
}
scale .1
}

I totally agree, though focal blur should help tie the blurry HDRI
background to the sharp foreground a bit better. But in any case I'm going
to experiment with some kind of ground.
Good suggestion regarding the board, I hadn't thought of that (and I don't
play it myself). I'll add one now.

Here's a redesigned board, based loosely on a few boards google found. It
seems wood+marble don't usually appear on the same board so I went fully
marble, with a chrome line to outline the board. Not sure I like the chrome
line, I think I'll try an inverted version with white marble border and a
black line...

Wow!
Now, I'm going to pick on every little thing though, since you want
suggestion to make it more real. Anything I wouldn't expect in a photograph.
What my eyes first noticed was the 'noise' just below and to the left of
the sphere. I don't know what AA settings you used, but changing that
could either soften and spread out the highlight and make it look more
real, or get rid of them completely which probably wouldn't look as nice.
The background is very blurry. My camera seems to think that to get the
background that faded would require a very narrow depth of field, if the
table is normal height off the ground for an outdoor chess table. A
little blur at the far side of the table would take care of that and
might even convince the photographers that this is a real picture.
Lastly, the table edge itself. I love the pigment, it looks just like
the composite stone I would expect to find in a park. My eyes say that
each chip in the stone seems too flat. I would suggest normals, but it's
the shadow that gives it away. The shadow of the board on the lower
right looks too crisp as it passes over each little chip. Similerly, the
green on the far top right looks just as bright as the near green
specks, something I wouldn't expect looking at that table. The little
bit of lens effects you mentioned might take care of all of that without
resorting to anything more complecated.
I linked the picture to a friend, fellow computer geek but not into
graphics. His response was, 'wow, wait, that's not real?' Personally,
I'd want this as a desktop, or a poster as is. I can't wait to see it
when you are finished.
