Okay, I'll show my stupidity here.  If I use a plane that is parallel to the
back wall won't it be flat?  How can the
tree and camera be inside it?  I could see a box since it would "fill" the
scene but I don't understand using a plane.

I wanted to update an image I made back in 1999, and I
think your bonsai has given me the final push.
Again, great image. Waiting to see the media version.
Bye

PS: Just if you are curious, this is the old image:

I think he means you'll have to create a plane and rotate it
so the +y axis of the plane points to the tree and camera.

Planes have insides and outsides just like boxes or spheres. The
"underneath" part of a plane is considered to be "inside" it. So just make
sure the normal of the plane points *away* from the camera, so that the
camera is "underneath" it.

Impressive! I can't wait to see it with media.

My only nit to pick is that the whole bonsai - even the leaves - seems
luxophobic. Shouldn't at least the leaves make some effort to point to
the light, instead of away from it?

Well the entire scene has all ambient turned off.  It might be caused by my
radiosity setting being too bright.

 It was exactly the contary (it was 4:30 a.m.)
Sorry for the inconvenience

What a stunning little image... The colours, the sense of sunshine... The
tree looks cool... That moss is brilliant too... I _like_ this!

Not sure if that's a good idea, myself. Hazy air can be overused sometimes.
I think this looks nice and clean as is, like it's sitting out on a patio
outside instead of a closed space.

While looking at it here I couldn't help thinking that if I could see just a
little bit of a background landscape showing between the bamboo screen that
I'd feel more in the picture than out looking in. Just a thought. Not
anything but a little sky, vegetation, and building colors; with only very
slight hint of there being something back there. In fact, it almost starts
to look that way when I scrutinize it more. It's a fairly small image as
seen here.

There is a little background behind the bamboo.  It is more noticeable in
the larger version.  I didn't want anything obviously behind it only the
hint to avoid detracting from the main focus.
