Ruin on Islet
Description: A lot of imagination went into the name giving :) The ruin is from DAZ3D, the trees selfmade. The sky is a photograph, but not the same as on Islet with Ruin, it was taken a minute later. Lit by the sun and a second sun and an additional light to brighten up the shadows a bit. Minor contrast enhancements in PS.

Another good composition with a brooding sky, my only technical criticism is that the tree trunks on the left seem to be glowing slightly. Of course this could just be an "effect of the light" - which I have seen before in real life, but given that I know this is a render, I would say that this flat lighting is giving the trees on the left a bit of a card board cut out appearance. The water is very good, I like the way it ranges from bright reflection on the right to dark green on the left. It does not give me much impression of transparency, but anyone who lives by the North Sea for example, does not come to expect sea water to be anything but an opaque brown grey topped with creamy foam.

Very wet looking water Horo. I disagree a tiny bit with David in that I think the water is actually very transparent. I think that the ground plane underneath has a green color and therefore gives the water a greenish color. I see no reflection on the water surface, only specularity in the water, as I see no images of clouds on the water surface as reflection usually creates. Specularity instead of reflection looks more real to me, and I'm certain it is the route Horo went in this case. As I've mentioned many times, in Bryce a certain amount of reflection is automatically assigned with transparent refracting materials, so there is no need to add any extra reflection value when rendering with normal lights. Scenes lit with .hdr are a different story. He has a super high specularity setting and that is why the water responds so realistically to the light from above. In both scenes the wave or bump pattern of the water surface is very realistic and has a tangible "breaking" action, though they are slightly low in regularity or frequency. The scale of the waves is slightly too big. Horo has also kept the diffussion values low so the water looks like water and not like ice. Diffussion values above 10 tend to "harden or solidify" water effects. Please tell me Horo if this water was derived from our earlier discussions on water materials. If so, it looks like the results are favorable as the water does indeed look realistic.

As lighting goes, I like the arrangement alot. You are very accomplished so I am picking on you a bit perhaps. As far as I can tell in this scene, the sun is not directly viewable and is completely hidden behind the clouds. In nature when this occurs, the light from the sun diffuses within the clouds before reaching the ground instead of the light beaming directly from it's single source, it sort of rains down from a bunch of different directions. Example, I notice that on cloudy overcast days shadows tend to be very soft, and very much right under foot. They don't stretch, because the light is coming from so many different directions. In this case all of the light is indirect, none of it is direct unless it streams through the clouds in an opening. The shadows cast by the trees are much more elongated and intense compared to what nature would create, although I'm probably the only freak who would notice it. This scene is actually a very powerful study in indirect lighting. This scene is deceptively complex and challenging in the way of lighting it realistically. These "gray" scenes are alot more challenging than they at first appear.

Water & Light

Rashad, you're absolutely right concerning the water. Because of the high transparency (99.6%), I had to put an additional plane underneath because the square of the terrain showed up. And it has the same material applied as the islet. I agree that the frequency is a bit low. No ambiance but a lot of specularity on the water.

Light and sun. Indeed, there is something wrong and I struggled with it for quite a while but could not do it right (that's why I tried another islet thing). The sun is where the shadows from the trees indicate and not at the bright part of the clouds. The photograph needs that light. I liked very much how this bright part of the photograph shines on the water but I knew it was all wrong. I tried to make the trunks with not casting shadows to fool the observer into thinking the sun comes from the sky ahead and not from the back. But that looked even cheaper. So I left it as it is shown here and made the other one.
