Hi again:
Thanks to all for the comments on the prior wip. Sorry, but as the
lazy I am, I've been delaying the replies untill I had ready the next
wip... ;)

I've used a real model for the streams, but the problem might be that
the pipes are not very visible and must be lower respect to the water
levels. Thanks for the tip about the leaves: I've reduced the phong now.
I also reduced the grain on the isosurface floor tiles.

Well, I forgot to mention that I used a two-pass method for rad, with
simpler geometry and textures for the saving step. Anyhow, it is slow on
some of the isos with more complicated formulas.
I also changed the white balance, you were right about it being too
neutral. The noise on the isosurfaces is now a custom pigment, wich
gives better results getting ride of regularity. Better now?

Yeah, they were too simplistic: I've worked that a bit.

Done! :)

I'm trying to find a good balance, but it is a specially difficult
scene, and could vary highly from monitor to monitor...
Jim Charter:

Neither me, but I started with the tutorial on the docs, and casually
one of the examples only needed an inversion to resemble somthing like
an arch. From here I started to tweak the shape by trial and error.
Later I added some noise with pigments, and lerned with Mike tutorial to
"join" shapes for the columns. Hard but really funny!

Very nice fountain! Thanks for the tip. I was already making it with
a sort of "boiling water", although it's not very visible.
Thanks again for all the suggestions. I will post the final image next
time, with some details enhanced (and the posible comments to this one,
of course!).
Regards..

Jaime, please stop posting photographs!!! ;-)
There is much improvement with respect to your WIP 2. The tree
leaves look real to me now. Nice work.
But I have noticed that am not very good at judging
"photoreality". Now I will just go sit in a corner, waiting for
others to comment on the image. :)

The closer you get the pickier the critiques.
The one thing that i.m.o. is a bit out of tune with the rest of the image
is the regularity of the wooden fence, in shape and colour.

For this I always go around with the colour picker, it shows that there is
relative little white an blak in places where to expect it. Highlights on
the palm leaves, the plant in the corner even has no pure black in it. I
modified contras in the gimp, you could make the shadows a tad darker and
the bright part a lot lighter, The flat piece on the foot of the first
collum on the left could be very close to white.

Nice colors but there is something wrong about the lighting. While the
sunlit surfaces are fairly dark the water is somehow 'glowing' quite
strongly.

I have never travelled to Spain, but such architecture with courtyards
can be found in Mexico. A very civilized way to live. Memories of my
honeymoon.
You develop your pictures with such patience that I am not sure whether
to take it as finished yet, but coming along very nicely indeed.

Hi Jaime
Great stuff as always ! The plants and fountain are impressive.
My only nitpicking would be that, given the lighting, I'd expect the lit
part of the walls to be much brighter and overexposed. Perhaps you could
raise the brightness level a little while keeping the dark parts dark. Yes,
I know how hard it is to get this sort of balance right ;)
I don't have much reference pics, but here's a few :

They seem to fall too horizontally in the beginning also.
I guess the water that flows out of a fountain doesn't get such a high
horizontal speed.
The curve seems too circular in the beginning.

> Hi again:
Hi Jaime - beautiful image. I wish I had the time to try
something like this. I think the problem with the water stems from
there, (seemingly), being no irregularity. Water pressures fluctuate
in any system, and as a result, you get different flow paths at
different rates. For example, if your fountain wasn't installed at
exactly the right angle, i.e. it leaned a little, then the flow would
be stronger in one part of the fountain, and weaker in another part.
Also, those holes that the water is coming out of would vary in size
too, not a lot, but enough to distort the water differently than the
others. This is also true if, say, one or two of the holes had
suitably large pieces of grit cemented inside the holes as part of the
fabrication of the fountain <lazy builders!> - the water would vary in
its flow. I also think there would be a little more splash in the
water (lower part, not sure about the upper part), with it streaming
from that height, and where's the ripples from those splashes?! ;)
I'm also not sure of the arcs and angles of the flow, but I think
you're not far from it.
Hope this is of some help. Looking forward to the next one. :)
