Very cool. I would most definitely buy these from Zazzle!

Thanks for the positive replies! Really very nice to know people enjoy them.

Sorry about the paper size, I naively assumed the A sizes would be used world
wide. Like 50 x 70 cm or 20 by 28 inches. Looking up CMYK at wikipedia
(;-) I figured that my knowledge deserts me there. I'm not forced by anyone to
use GIMP, it was just the best (free) I could find. But if anyone has
suggestions for the best software to use (preferable free, or else at a "normal"
price (like up to $100), any advice is welcomed. Prints are pretty expensive, so
I would rather pay something for good software, than have to find out the colors
turn out bad on the posters....

for sure.

But thinking about a bit more, these are povray renders, so I guess the task of
generating those mostrous pixel-wide images is up to povray. :)

Regarding CMYK and prints, if you use an online gallery such as Zazzle or
Deviant Artists, the task of actual print for sale is up to them.  You only
provide the images, they provide whatever CMYK conversion is needed for print...

If you're still doing on your own, I really don't know how to help.  Seems like
CMYK is kind of a little professional dirty secret they get only to themselves,
like professional magicians, so as to keep competition away.  I thought
Paintshop Pro would support it, but alas, being a free tool never seems to get
you this...

I guess that's because there is no such thing as "the" CMYK color space. 
You have to know a lot about the pigments and the paper that will be used.

I want to print them with the white or black rim (passpartout) and the texts,
which I do in GIMP. Is there an option to add the rim and text in POV-ray? I
figured that the perspective would distore the text, if I tried that.

Do you mean as a private individual? Yes, sadly no company or friends in
IT/printing business behind me. I might walk by a printshop for some advice
then, see if they can help.

Okay, I'll just have to try it, then. I'll need prints for my exhibition, so I
might as well upload one and consequently order it as try-out (paying for my
first
royalties myself :-)

Thanks for thinking along with me, Joost

You could render the framed image in a separate pass,
basically loading the "painting" as an image_map. And
rendering it with an orthographic camera together with
frame and text. Also, screen.inc might come in handy.

To know the pixel size you required, you first need to know how large 
the image will be when printed, and you multiply that by the DPI setting 
of the print.
A large, A size, print should need about the same pixel size as a 
smaller size A2 print. Normaly, you look at the larger print from 
farther away, so you can get away with a lower DPI setting. Just look at 
a billboard from normal distance and close up. It may have a PDI of 
about 0.5 to 2 ...

Once it's done, you just start the render with: +wxxx +hyyy -d +fn

xxx and yyy are the horizontal and vertical pixel dimentions. You are 
never limited by the resolution from quickred.ini, you can render to any 
arbitrary dimention you chose.
-d suppress the display window under windows and mac. Usefull when you 
render at a very large resolution.
+fn set the output format to png.
As you have large areas of uniform tint, you'll get a good compression 
ratio: Large image, small file.

You put in two o's too many, stupid!  :-)

That is excellent work indeed. I love the fact that they can be admired as 
well at thumbnail size as at full size, increasing the range of possible 
uses (post stamps for instance).
