As you know , I had been posted the original Autochrome RGB Spectrums. I am thinking to order a filter set from labs specially made for match the colors of Autochrome.

It will be a trichrome process.

I am looking for someone - May be Ron can do it , I dont know yet - to draw the curves of each filter with including bw or color film sensivity . Who can do it and what cost ?

Can filter guys can do it ?

Second , can trichrome photography could be done with color film , is it suitable for that ?

Thank you ,

Umut
