I’m having a problem with metering color temperature with the Illuminati Meter when using it with my studio flash. Sometimes, it gives me a color temperature reading and then, when I test fire again, I get no reading. It seems to be an issue with how powerful the studio flash is set. At full power, I usually get a reading but, as I reduce the flash power, I often get no reading. (These are studio units not speedlights.) I’m using the iOS app on my iPhone 8. Is there something I’m missing or is there an issue with the meter/app?
