yann.. thanx again. i finally "solved" it..
the weird thing that just totally set my up was, that as soon as i opened the messured data it also filled in the reference but with totally wrong patches visible.. some light magenta.. but that was all.
i finally just gave it a try.. and it worked.. lol
i now opened a new thread on how to achieve a greater gamut.. if u can help me there?
thanks a lot
