Hi,
Not an expert at all, but I did some investigation time
ago. Basically the encodings used by TIFF Lab and ICC
are different on some photometric interpretations.
See the details here:
http://www.asmail.be/msg0055212264.html
By the way, in the CVS there is a new tifficc that
would support some of these encodings. I can post
the piece of code that does the trick if wish so, just
let me know.
Regards,

Thanks for advices, code implementation was easy and is working fine now,
but...I met some strange things in converssion tiff file with LAB to the RGB
colorspace. Colours change in strange way and are not correct. Colorspace
conversion works, becouse I checked it with couple of different ICC-RGB
profiles and allways image colours were changed.
I tried to apply LAB color profile first and than convert to RGB (colorspace
conversion made twice), but nothing happened, colours were still .
If you want I can send that tiff file to you...so you can check that...
I am not an expert at TIFF LAB colorspace. I know that there are
experts on this list.
