After reading a couple chapters of Jeremy Birn's Digital Lighting &
Rendering, I decided to try rendering in passes (radiosity pass, shadow
pass, etc). Saves a lot of time and I can make slight adjustments with more
control, i.e. adjusting the darkness of the shadows.
Anyway, here's the result of the effort so far--still a bit too finish:
stove, microwave, windows, etc--but comments welcome (about the image or
rendering in passes). This image was done in 3 passes: radiosity pass (8 hr
render time), shadow pass (5 minutes) and sunlight pass (2 minutes). The
image was then put together in GIMP.

I like the microwave as-is; you put the food in, it cooks it.
None of that plunking about with figuring out how long, the
microwave already knows...;)
As far as rendering in passes...it takes away from the idea of
doing the whole image with one program, with one pass. That's
my motto...'one program, one pass'...eventually there'll
actually be software that can do that, with any scene at all.

I've not tried this with pov but it is rapidly becomming the industry
standard method as it's faster and offers more control.
I may have to try this with my current work as the render time looks like it
will be months!

I have to say that the lighting looks rather fake to me.. except in the
spot where the sunlight hits the counter, that looks really good (huh?
go figure).

It looks fairly good, but as i understand your method it's not very
realistic, the different aspects of lighting do not interact with one
another. For example if you have sunlight coming through a window this
should have strong influence on the radiosity distribution.

Nice Bebraistic kitchen, especially the radiosity... but the whole thing looks
a bit sterile, no dust, no bread crumbs, no dancing dust particles in the
sunlight... hard to decide whether its a real or a dollhouse kitchen! And I
can't help, even the wooden doors look somewhat like plastic...

I'd never use the dishwasher, too many buttons.
The rendering in passes idea is interesting, have you got a web space where
you can put all three images so that we can have a closer look?

I have not read the source you quote but the result is quite pleasing. It goes
to underscore that there is no absolute standard for "realism". The still,
suffuse sense of light reminds me of William Bailey paintings.

Is there additive layer mode in Gimp? Can it display real time
gamma corrected preview when layers are edited. Can it do this
for 48 bit images?
These are the requirements for high quality composites of
different light contributions. Because the source images
must be linear, 24 bits doesn't leave much room for editing.
Were the source images linear?

The stock Gimp still works in 24-bit colorspace, but there is a
"hollywood" branch that does 16 bits per component.
