Hi I measured my illuminant spectrum using spotread -a -s -H using a colormunki photo, and saved to solux20121114.sp. I want to use this for creating a camera profile. I scanned a photo of my it8 target using scanin -dioa -p -a -G1 -v1 IMG_0523.tiff it8.cht R080505.txt but when I do colprof -v -qm -am -u -i solux20121114.sp -O solux20121114.icc IMG_0523 I see the error message in the title. I get the same error message when i use -i D50, which is the default according to the manual. But when I leave out the -i alltogether, I don't get an error message. Am i missing something? Jos
