Lumu Labs a Slovenia-based Kickstarter launched the Lumu, a headphone jack attachment that turns the iPhone into an accurate light meter for photographers.
Back in 2013, raised over $244,000 on Kickstarter. Now the company is back again with the Lumu Power, a next-generation attachment to your iPhone that doesn’t just meter light — it can measure and calculate flash and color temperature as well.
Quickly measure the color temperature in Kelvins. The White Balance mode in the new app can show you the measured temperature value and the value of Tint compensation you’ll need to achieve a perfect white in your resulting photos.
For flash photography, the Lumu Power can measure flash exposure and the flash versus ambient light ratio.
The retail price once the Lumu Power hits market is expected to be $299.
