Error – Generate cone mapping model from chart

Hello,

I am making some test with .ORF photos I have available and that were taken under a white light artificial light (not outdoors light as you strongly recommend). When I am trying to generate a cone mapping model from chart, using D65 300-700 as illuminant and Blue tit receptors, I get the error: “the illuminant and chart wavelength units are different”. I would like to know if it’s because of the light conditions of the photos or because I made a mistake somewhere on the process. I don’t have pictures of the x-rite colour chart alone, but as part of an image. Perhaps this is also contributing to the problem?

Thanks a lot in advance!
