Hi Daniel,
I think you are referring to transmissive. I agree with what you have
said.
However, I am interested in emissive. This would be reading taken from
CRTs, LCDs, and video projectors.
Thanks,
Ray

Hi Ray,
Emissive readings should zero out to clear film for absolute, and to
unrestricted light (nothing) for relative. It is the same as in reflective
where a predefined ceramic is used for white in the case of the latter.

what is the reference when making emissive readings?
