Lumu Power Turns the iPhone Into a Light, Flash, and Color Temperature Meter

Back in 2013, Slovenia-based Lumu Labs raised over $244,000 on Kickstarter to launch the Lumu (currently available for $150), a headphone jack attachment that turns the iPhone into an accurate light meter for photographers. Now the company is back again with the Lumu Power, a next-gen attachment that doesn't just meter light -- it can measure and calculate flash and color temperature as well.

This Cap Doubles as a Gray Card for Light Metering

Starting in late 2014, COOPH (The Cooperative of Photography) began selling multi-functional clothing items designed with photographers in mind. One of the products is the Gray Chart Cap, a series of caps that have gray undersides that help with light metering.
