Finally, after about four months.

The scene is inspired by late nineteenth century paintings of the Late 
Romantic school and Genre pieces.

This is about the first scene were I made /really/ use of pigment 
patterns (road, thatched roofs, dirt on walls) and the Displacement tool 
in Poseray (thatched roofs). Those will be tools I shall come back too 
frequently.

Great ! The perspective is very welcoming and background trees are quite
detailed.

Excellent! I very much like the feel of it.

I hope it's OK that I've borrowed your image to test an idea? Namely, 
using the extended AA jitter capabilities of the povr branch for a bloom 
post process feature.

It's something like what Sam Benge was playing with 6 or 7 years back - 
except less "luminous" oriented. The aim is a filter to take the edge 
off rendered images; Something which makes the result look less 
rendered/perfect/clean.

Attached a result. I expect it can be better tuned, but I'm happy that 
it looks workable on the first attempt. It is not cheap as post process 
features go. Twenty minutes or so on my two core i3(1). As currently 
implemented it's a two stage, nine render total process. All POV-Ray 
(povr).

(1) The sampling could be done against the original scene - but that's 
more expensive. However, it would be an approach more true at the edges 
of the image.

A bloom can be useful. What's nice is that there is no artefact, but currently
everything is blurred. Could there be some contrast or value threshold to make
it  less destructive?

Wow, this is really impressive Thomas, nicely done sir! Nice lighting, it's such
a pleasing composition and mood. And I see the cat made it into the shot :)

Cheers,
Rob

This initial implementation blooms into everything - so it's going to 
blur to some degree, if you use the filter. You can lesson the bloom 
strength - make things sharper, but then the bloom effect itself fades.

An enhancement that could be tried I suppose, would be to leave "dark" 
to some criterea regions untouched. Not sure how "natural" it would 
look. More complicated things always possible - but then it might be 
rendering large and scaling down say is a better way to go. At some 
point if you don't want a bloom filter, you are into something else.

On the time to run this filer... I remembered after posting I was using 
a development, '-O optimization only', build. It'll be faster with a 
normal performance compile/link - but still expensive.

Well done, Thomas.
You were really inspired here!
I wouldn't mind living there.

Cheers

You are welcome; be my guest.

Ah, yes! Luminous bloom! Something I have long intended to use indeed

Not (yet) convinced. Like Mr says, looks to much like blur here and 
everything is blurred.

I have the intention to do also a stochastic render of the scene. I 
/think/ that would give a better result. It probably will take some 
extra render time; the present render already took about 12 hours, 
especially the upper half of the image obviously because of the trees.
