I use a calibrated set of BCRA tiles for reference...
Those things aren't cheap, as I understand.
Seems to me there should be some not-miserable way of making / getting "close
enough" standards. They wouldn't need to be spectral matches for BCRA, but
should be sufficiently diverse to be functionally equivalent -- check response
over a wide range of spectra.
Teflon / PTFE thread seal tape makes a shockingly good white reference, but
nothing else comes to mind for other colors. (Well, a light trap for "pure"
black....)
Anybody have any suggestions?
Ideal would be things that're intrinsically stable and predictable. "Mix
roughly two parts of this and three parts of that and bake at somewhere around
300°F for an hour or two and sand the surface smooth." That sort of thing.
