where to get macbeth colorchecker?

Hi!

I will go to make some fotos of a building that will be modeled and rendered
in
radiance (to do some research on previous concepts of this building). I want
to use
these fotos to get an idea about color. So I wanted to use gray levels to
determine
the reflectance and fotos to get rgb values (in fact I wanted to do this as
described
in "Renderin with Radiance").

Now I have problems getting the Macbeth Target. We us Kodak targets here,
but
those are not supported in the radiance "color management".

So, is it possible to use Kodak targets with radiance, or do you know where
I get
Macbeth colorchecker in Germany?

Thank You, CU, Lars.

Hi!

Thank you for the address! I just have ordered one at Calumet Photo,
Hamburg, it is about 165 DM there. Has anybody experiences with this kind of getting
material parameters? Any hints? My flight goes on Thursday ;-))) What should
I know BEFORE taking photos?

CU, Lars.

Most importantly, you should know that the photos will NOT give
you any realistic color values... But you probably know that
already. The best thing would be to compare the colors of the
real object with those swatches *in the same lighting conditions*,
and to only use the photographs for sanity checking the results.

If you *only* compare with the photos, then the use of any color
calibration system really sonds like a waste of time.
