I published the chemical numbers and mixing ratios for coloring autochrome grains. Big question, Can Janpol lens create each one of these dye colors - for 6 different color masked pictures of same subject to later all meet as autochrome - I know each dye have different spectrums, if that does not work , I think only way is to invest in these dyes and make colored filters from them. Is there a third way ? Umut
