Hi everybody, I'm still stucked with my spectral flash measurement problem. I got a EFI 1000 (an eye one pro Rev.D) without the ambient head accessory. I tried Argyll and EyeOne Share without success. EyeOne Share says my instrument cannot take ambient or flash measurement. Does the EyeOne know if the ambient measurement head is on? I have the opportunity to borrow a Colormunki, do you know if that would solve the problem? Thanks a lot, matt
