this test. I was trying to see if my lighting macro worked fine with glass
and photons, and casually I also intended to obtain well balanced images,
without the need of external postprocessing. Not for "purism", but rather
to have it achieved on one pass: I'm lazy, do you remember? :)
IMHO, these two images do not benefit from any autocontrast, normalizing,
color enhacing, unsharp mask, etc... I'm still not satisfied with photons,
but I supose it's only matter of decreasing photon spacing. I also tried an
area_light version, but my patience is very limited...

See attached image with side by side (one on the right has had a slight
contrast tweak) and IMO looks much better.

I look forward to the completion and release of your lighting macro (you
ARE releasing it eventually, right..?).
One flaw I notice in the second pic is that the focal blur and change in
contrast makes the glass appear to be pasted on top of the background;
it also has a uniformly faint shadow that might account for the illusion
as well.

IMO, it ruins the blur on the tile wall and causes the glass to look
cut/pasted in.
I think the image might have benefited by having some of the yellow
reduced (easily accomplished in POV), but there are other, more on-topic
places to discuss and demonstrate second party methods of doing that.

I really haven't followed this newsgroup for long so I have to ask what
exactly is this lighting macro of yours?

Simple but yet it makes envious of your skills. You are the master of
photorealism. I really don't see the minor 'flaws' the others have
mentioned.

Awesome! I especially like the photons in the first image.

No one else said it, but.... WOW!
I'm going to make one of these my desktop just so people inquiry as to why I
have a *photograph* of a glass of water as my background.

Woah... wait a second...
you posted two images. Originally, when I first looked at them, I was
comparing the first to the second, believing the second was a photo that you
had based the first one off of.
Now I realize the second was also a POV-Ray render.
Good job =)

Jaime's light macros can be found here:
http://www.ignorancia.org/lightsys/
It helps you set up lights in POV that interacts realistically.
