Title: Dry and Blasted
Post by: AP on September 01, 2011, 03:56:24 PM
A lifeless desert landscape with what could be a uni-directional form of erosion over the basin.

...or "land of the banana rocks" :)

The atmosphere seems all hot and unfriendly, so that's good. If I may, I find the color mix betwen stones and sand a bit strange. One would expect those to be more uniformly colored I reckon?

Cheers,
Frank

Interesting idea, and a good starting point.

I agree with the previous comment, though. The sand is after all usually the bits of rock that have been eroded away, and which in turn sandblasts the remaining rocks to further erosion, and so one would expect the sand and the rocks to be basically the same colour. If all erosion is in one direction, it is possible that it is not necessarily so, but one would need to see bits of sand on the rocks, I think, for the image to look more natural.

I see where you've taken some inspiration for the choice of sand/rock colours. http://forums.planetside.co.uk/index.php?topic=13065.0

I have seen images of tilted stones near Las Vegas, neat stuff. Just rare to see.

There are some desert environments that have a very distinct separation of the rock color and sand/dirt color beneath, just not as common i gather. The stones could be chemically oxidized/heat baked based on there makeup while the soil is made up of different factors with less of a chemically eroded result and the like.

It depends on how the surface materials are spread out i suppose. Some zones might be more porous and others more hardened. That might play a role as to how there are distinct variances within the rock to soil factor. There are bits of sand on the stones, hard to see though. Using the coverage percentages is not easy.

ground is too smooth and has no pebbles...also needs more real colors, then good.
also make rocks more cracks and breaking apart

That is sand. It is supposed to look like that. The colors are quite accurate.
Not all rocks have cracks. I have seen rocks like this myself when i visited the desert.   ;)

Another version, this time i am trying to make it look semi-photographic.

Look better with blur. This is what I mean about rocks.. see the look of these?

Thank you. With the case with the rocks, there are so many different varieties of rocks on this planet with so many varying degrees of colors, textures, shapes that not all of them look like the photograph you had posted within a arid climate such as the one i rendered. Even within the exact same environment, rocks can vary greatly. Trust me, i have seen it for myself. However, the rocks within the photograph would serve as a nice test idea for another render in the future.    ;)

Wow, nice halos. How did you put them into the render, did you use HaloSim or just postwork?
Title: Re: Dry and Blasted

Just some post work trickery from Photoshop, that is all.

Ok! I thought you used halosim.
Nice 22ยบ halo, circumscribed, parhelic circle, sundogs and tangent arc though!  ;D

Don't remember seeing this type of sand/obsidian stones in nature somewhere; and, must say it a very appealing contrast. Very good work here.

It is not to common i think. Out in Utah and Nevada as one series of locations, there are stones that are near smoothed dull black that contrast well against orange and red sandstone deposits along the eroded slopes and basins. Neat stuff.    :)

Now I remember; saw this combination while hiking in Utah back in the early eighties. Utah is amazing in landscapes.

Yes, i very much want to live there but i need to see if Salt Lake City is livable. Wonder what an artist does there.    ;D

Not sure of the job market there; but, well worth exploring. If you make a connection and can settle working there, you're in for a treat. I've done the 'Grand Circle' trip over a period of about 12 years. Some places, you'd believe no person has ever set foot - an amazing place.

In some places you can see large difference of colors between sand and rocks.
An example :
Tagrera, South of Algeria (http://wiwine.christianfly.com/img.php?id_img=92)

Strange stones :
Erg Killian (http://wiwine.christianfly.com/img.php?id_img=192)

Why not in blue ?

Do not limit your imagination !

I get it TheOne. As a fellow who carefully studied many types of world Geology and Geomorphology, i can only get so real. If i had my way i would render this with full-on procedural erosion to but we do our best with the limits of software.
