OK, I'll bite. I view tracing as just one step in a multi-step workflow.
Also, any trace produces a file that can, at the very least be enhanced
with:
unsharp mask
color correction (most traces have color casts)
contrast expansion (auto leveling)
Now the above items are independant of the actual scene. Some scene
dependant things are changes in color or sharpness of objects, exclusively,
and outside the ability of a general traycer, such as what I did to the
image.
Of course, rt purists will disagree with the above, but as with anything
artistic, it's all a matter of taste. I want the best finished product I can
get. If that involves post-processing the image, so be it.

Sure, if that's what you want, but is it on-topic for this server? I
just don't think so. You are free to disagree. They do provide an off-topic
group if you really want to talk about paint programs.
Philosophically, I see any degree of post processing as similar to
raytracing a sphere and then drawing dragon wings on it and saying "Look
what I raytraced!". That's fine if you want a dragon and can't find the time
or talent to model one, but it's not raytracing and it is -definitely- not
PovRay.

Try to find an advanced or professional CG artist who doesn't
use post-processing and multiple tools. Compositing, layering,
filtering etc. are techniques frequently used by professionals.
POV-Ray generates good quality raw material to be processed and
refined by other tools into finished product.

Well, you're discussing this in terms of black and white and I am discussing
this in terms of shades of gray. I took a POV Ray-Traced image and did some
color adjustment and sharpening. I would still call it a 99% POV image and
therefore revelant to this group. What percentage is relevant and what
percentage is not is, of course, a matter of opinion.

Try posting a povray image on a photoshop forum.

I don't think you will find me arguing with that. Every single one of my
professional images were handled by other tools to varying degrees. But you
won't find them posted here. In principal, I think it is a bad idea to start
having more and more post-processed images archived on a povray server.
Slippery slope and all that.
If you are posting here to show what you can do with povray, you should
do it with povray. I haven't re-read the AUP, but I will bet that there is
something about this server being maintained so as to demonstrate the
features and quality of PovRay, not PhotoShop.

Oops, sorry, I read your post too quickly.
I thought you were asking what they were.
Just more literature from the unwanted education department.

OK, I started a 2048x1536 trace this afternoon, with +a0.3 +r3 +q11 and I
raised the count in the radiosity from 100 to 200. Hopefully, this change
won't screw anything up. I'll post the image when and if it ever finishes.

So would you be happy if we put up a povray.purist group?

I have post processes EVERY image I have ever rendered to some degree.
I do not have the cpu power, time, or patience to re run a several day
render just for the sake of a couple of minor flaws that can be fixed in few
minutes.
often recreating some of the post tweaks in pure povray can significantly up
the render time. its hard choosing between an extra day (or 2) rendering, or
a few mins in photoshop.
A prime example. I recently rendered some items on a plain with blured
reflections and unfortunatly after a 2 DAY RENDER the resulting blur was
lumpy. photoshop fixed the offending lumpy spotchy mess in 5 minutes, viola
perfect image. There is not a cats chance in hell i was going to hike some
of the renders setting up and re run it.
Dont force us all to conform to your use of povray, its just one of many
tools.
(followups to pot)
