Rudeofus , Keith ,

Thank you for the technical advise. I thought that if Philips succeed to create a television monitor , I could do the same . But I think its too difficult or hot to handle. I have put the idea , if someone finds a better way , I would be happy.

I contacted with Sigma again in Istanbul to get the spectrum curves. Someone told me about Photoshop LAB and curve transfer in to it but I looked to tutorials and I want to ask that is it possible to carry whole dye spectrum to LAB or is it not too precise ?

I did not see a autochrome with my hands but all I see are web pictures and may be done by photoshop.
