Re: Generate profile from 2 versions of photo?

Hi,

In general, you cannot do that because the transform should
describe all
colors, and the image may miss some. You can, however, use
images with added
patches sampling all color space, and then build a color map
with the
transform. I think Kodak has some patents on this method.
ICC way does not
use that but instead a device independent color space (Lab
or XYZ).

Regards
Marti
