Hi,

Attached are two small TIFF. One has a D50 profile embedded, the
other has  a D65 profile (sRGB) Both profiles has same gamma and
primaries, but different white point. They had  been embedded
with tifficc utility. Seems Photoshop does some tweaks on embedding
profiles.

Open both tiffs. When photoshop asks "The current embedded
colorspace..." then select "use the embedded profile"

When you convert the D50 image to, for example, sRGB with absolute
colorimetric intent, you will see a strong yellow cast (this is D50 as seen
in a D65 monitor) The sRGB one does not show this cast, since it is
already on D65 As said, white point is only taken into account with
abs. colorimetric intent.

Assure to have the windows monitor profile set up. Photoshop does
use it.

Regards,
Marti.

Hmm, I can't seem to get photoshop to honor the white point of an
embedded profile. Anybody got a working demonstration of that?
