Gear Patrol reviews Lumu
From the article, featured in their special Film Issue:
“Lumu couldn’t be easier to use, even if you have no experience with a hand-held light meter. Just plug it in, making sure the white light sensor is facing your camera. Then hold the meter up next to your subject, whether that’s your five-year-old kid, your favorite timepiece or your vintage Corvette, and click “Measure”. The app immediately displays the correct aperture and shutter speed required to expose the photo properly.”
