Great image!

The blur is probably justified to simulate the photographic
effect at this scale and distance. On the other hand it can be
considered an unnecessary image defect ;) will be interesting to
see if expectations change with future light field cameras that
can achieve full focus anywhere. Anyway I think it would be
nice to see a render w/o blur for comparison.

For such a scene (not many reflections) focal blur could probably be
faked as post-processing based on depth image with little loss.

Many thanks for posting the code. I'm just rendering it. As I stated I was more
interested into your textures, since I fail a little bit due to this issue. I
came up with the idea to grew moss with the mesh-cam using your textures (I
posted an animation due to this issue some months ago). But I have to find a
proper parametrisation of a Lindenmayer-System, which is not trivial.

Best regards,
Michael

The first I did was to render a 8000 pixel closeup of yor excellent source (no
rad, focal blur, but double_illuminate) - and I'm more than impressed.
Last time I got this feeling was with some JVP or Sam Benge images.
At once I got 5 ideas to enhance own images - so thank you very much for the
source...

For me the close_up detail level is extremely good compared to existant
alternatives - including your own oldroyal moss (which I liked much).

But please improve your moss further, if you want to...

Hi Norbert,

Thanks, I think it looks OK close up but just does not look as much like 
moss and more like some kind of alien plant life which reminds me a bit 
of some of Christoph Gerber's images e.g.

http://gerberc.deviantart.com/art/Moon-21-336009591

I did some really close up renders of the moss (probably had a different 
texture as well). I think they are interesting but I would not guess it 
was moss at this level of detail..

BTW, your first attempt at this round of the tc-rtc looks very impressive.

That's the problem with cg: creating a picture large enough to print would 
require a render farm. This one looks nice, so it's a shame it can't go 
farther than a post to a newsgroup.

Still, it's nice to see something besides a Work in Perpetual Progress on 
this server. I peek in here every once in a while, and nothing ever seems to 
get finished.

Norbert work is impressive, but this is impressive too.

For someone who have seen some moss images taken at scales where you are 
no longer sure if it's still macrophotographies or should be called 
microphotographies, that moss looks realy convincing.
Yes, moss do tend to look other wordly when looked at from /very/ 
close... The same hold true for molds.

Another that might make an interesting "Elements of Geology" tc-rtc entry.
There are so many elements in dead rock that are absolutely necessary for
life.

That thought had occurred to me, especially as when moss grows on rock it eats
away at the rock therefore adjusting the geology in it's own minor way..

However, I did start working on this image about 5 years ago so way before the
tc-rtc round was announced ;-)

I am working on another image and if it turns out as intended will enter this
into the tc-rtc. Not going so well at the moment though so I will probably end
up submitting this one.

In some sense, I started working on every POV image sometime in the late 
90s. A scene refresh is much less a sin that using "absolutely necessary".
