The Illuminati light and color meter, from Illuminati Instruments Corporation, is a clever little device that provides all the functionality of a traditional meter, but uses Bluetooth communication and a mobile phone (or smartwatch) app as a user interface. This means it’s much smaller than traditional meters that have displays and controls integrated into a single unit.
What’s even more helpful is that a phone can be paired with multiple meters, meaning they can be placed around a scene and accessed from a single app. The meter can continuously monitor both ambient exposure and color, and warn a photographer if any changes in brightness or color temperature occur. What’s more, additional software functionality can be added in the future through a simple app update.
