The light metering tool for every great image maker.
Use the standalone app as a reflective light meter or use it in combination with Lumu Power hardware for professional Flash and Color Temperature measurements.
Lumu Power is an easy-to-use digital incident color and light meter that works seamlessly with the free Lumu app to deliver Color Temperature, Illuminance, Spot, Ambient, and Flash Exposure metering functionality on your iPhone.
A new expression of what a light meter can be, Lumu meets the needs of enthusiasts, professionals, and students who find existing light metering solutions too bulky, expensive, and complicated.
â€œThe Lumu Power is without any doubt the most full featured light meter I have ever owned. It's tiny, it weighs hardly anything, it manages to offer a feature set that expands way beyond what most will ever need from such a device.â€ - www.35mmc.com
