Hi List members. I have been wondering why the spectrometers that we use in colour management have not begun to include some UV measurement, given ISO3664:2009 requires lighting with specified amounts of it. Or in the case of the upcoming P3/P4 viewing condition, its absence. I use ours (XRite) to measure CRI/TM-30 of room lighting, and to check light modifiers used in our photo studio as they age, and that’s great. But I can’t use it for to check if lighting is ISO 3664 compliant. And that seems strange, given these spectrometers target market. Would adding UV sensitivity make spectrometers too expensive for not enough added value? Or are there other cans of other worms that make it not practical? I’m hoping those in the know could shed some light on this. Thanks Peter _______________________________________________ Do not post admin requests to the list.
