I created a custom illuminant file: spotread -a -s -H then, after calibration, I pressed the instrument's button and then 's'
Hi, a quick look with specplot indicates that the illuminant spectrum you have captured is: * very low level (not much light - practically zero) * has a low color temperature (2000K) that is far from the normal daylight or black body spectrum locus (10 DE) * is extremely colored compared to D50 (85 DE) If I were you, I would try capturing the illuminant again, and check that it looks reasonable (what sort illuminant is it ?) Try using the spotread -S flag. Graeme Gill.
