Extremely nice picture! Good atmosphere.
Once again, well done Thomas.

Cheers
Ton.

This came out well - the perspective / viewpoint works very well.

It looks very different between my 2 monitors.  I'm not sure how to
independently change the screen colors/gamma on my laptop but leave the
auxiliary monitor as it is.

Most noticeable to me was the wood railing - the colors, the texture/normals,
and the algae growth (probably because it's in the foreground).
As others have mentioned, the landscape and clouds are very well done.
The rusted bars are excellent - that texture must have taken quite some time to
develop.  (But perhaps they should not all appear to bent exactly the same).

The moss on the stone at the base of the railing is --- odd?  Unnatural?
Perhaps also add a bit of space around the post bases (larger hole, shadow) and
a bit of extra growth and rot where the water collects.

The castle looks very clean.  And perhaps add just a bit of texturing to the
little red roofs in the distance.   Maybe some bugs?  a bird?  a farm cart?

And really - those clouds are fan-tastic.

Good work, Thomas.   I'm glad to see some rendered fruits of people's effort
still being posted   :)

Thanks Bill, much appreciated indeed.

I tried to find the old TC-RTC site again but - even with the Wayback 
Machine - was unable to open it. :-/

Basically, the checkered fields are superimposed as a slope texture, 
taking into account a b&w diamond pattern image_map. In the original, 
the pattern was straight but I thought it would be more convincing if 
that were changed to a more wavy pattern.

The code for the landscape is as follows (you can extrapolate for your 
own needs):
//start code--------------------------------
#declare ImagePat = pigment {image_map {png 
"DiamondPattern_05b_inverse.png" gamma srgb interpolate 2 transmit all 
0.0 } rotate 90*x rotate 45*y scale 0.1}
//Map is necessary to place bushes and trees on the field edges:
#declare Map = pigment {ImagePat transform {HF_trans}}
#declare N_pat = normal {bump_map {png "DiamondPattern_05b_inverse.png" 
gamma 1.0 interpolate 2} rotate 90*x rotate 45*y scale 0.1}

#declare P_field1 =
pigment {
   agate
   pigment_map {
     [0.3 srgb <0.4, 0.5, 0.0>]
     [0.7 srgb <0.3, 0.4, 0.0>]
   }
   scale 0.01
}

#declare P_field2 =
pigment {
   bozo
   pigment_map {
     [0.45 srgb <0.7, 0.6, 0.0>]
     [0.55 srgb <0.9, 0.5, 0.0>]
   }
   scale 0.01
}

#declare Pattern =
texture {
   pigment {
     average
     pigment_map {
       [1.5 P_field1]
       [0.2 ImagePat]
       [1.0 P_field2]//srgb <0.5, 0.8, 0.2>*0.4]
     }
   }
   normal {N_pat bump_size 6}
}

#declare Patterned =
texture {
   slope {<0, -1, 0> 0, 0.5
     altitude <0, 0.0, 0>
   }
   texture_map {
     [0.10 Pattern]
     [0.15 Me_Rocks]
   }
}

#declare F_HF_01 =
function {
   pigment {
     image_map {
       tga "GC_Apophysis_06_hf.tga" gamma 1.0
       map_type 0
       interpolate 2
     }
     warp {repeat x}
     warp {repeat y}
     scale 50
     warp {
       turbulence 0.2
       octaves 1 //[6]
       lambda 1  //[2]
       omega 0.2 //[0.5]
     }
     scale 1/50
   }
}

#declare Fieldscape =
intersection {
   height_field {
     function HF_res, HF_res {F_HF_01(x,y,z).hf}
     smooth
     translate <-0.5, 0, -0.5>
     texture {Patterned}
     transform {HF_trans}
   }
   box {
     <-0.5, -0.5, -0.5>, <0.5, 0.5, 0.5>
     scale HF_scale * <0.99, 10, 0.99>
   }
   //rotate 90*y
}

Fieldscape
//end code--------------------------------

I suppose there are other ways to reach this, in particular by including 
the diamond pattern as a function into the height_field. It is something 
which I have not explored (yet) and I foresee a couple of difficulties 
with that approach. In the present scene I just wanted a ready-made 
landscape so that I could concentrate on the castle.

The pattern (Map) is also used to place the trees on the landscape by 
means of the eval_pigment() code.

The clouds are based on code by Juha Leppälä (as used originally by Mick 
Hazelgrove, who also posted it here, I don't remember when exactly).

The original image where the code was used. I have not yet found 
when/where the code was published.

Thomas,

great image, I like it. 
There is one thing I wonder about with several of your landscapes, they 
are desolate. Is that intentional?

Thanks indeed.

[grin] Good point. It probably is on a semi-subconscious level. Living 
in a country that is a bit too crowded for my taste (although I am in 
the less crowded northern half) is influencing my choices. Also, I have 
always preferred to visit landscapes "far from the madding crowd" out of 
taste and out of professional reasons (geology). Last (but not least) I 
am not a great friend of humanity in general...

I like to use Poser and I have made a series of scenes in the past where 
the human factor was present. This has drifted somewhat to the 
background at the moment. Otherwise, cities do not interest me. Maybe 
little ancient villages and - certainly - ruins, explain my (19th 
century) Romantic nature. :-)

Thank you indeed, Paolo. Somehow I wanted to include your Grunge texture 
but I agree that it is not yet perfect for the purpose. Some more work 
needed. As also the grass. Gilles' macros are great but have some 
difficulties. I am not done yet with that part.

I was in doubt about the trees because of their trunks. I may use others 
instead. The clouds are very satisfying. They are based on code by Mick 
Hazelgrove (and Juha Leppälä). I posted an address in my answer to Bill 
Pragnell. I have not yet found when I downloaded the code nor from where 
exactly. However, it makes fantastic cloud scapes. If the origin cannot 
be found, I shall post the code as I have it today.

Ah, the Eifel! Yes, that comes indeed to mind.
