Turn your iPhone into an incident light meter with Luxi clip-on adapter
A Kickstarter project for a device that turns an iPhone into an light meter has exceeded its funding target within days of being launched. The Luxi incident light meter adapter for iPhone needed $10,000 to start mass production and has already raised a cool $47,495 in pledges from 2,196 backers with 40 days left before the funding deadline.
The Luxi is a small piece of plastic that clips on the corner of your iPhone 5, iPhone 4 or 4S, covering either the rear or front-facing camera on the smartphone with a white dome, emulating the lumispheres found on professional light meters. Coupled with an official iOS app — which presumably makes sense of the information going into the cameraphone sensor — you can then reportedly take accurate incident light readings by holding up your phone and reading from the display.
The company behind the product is Extrasensory Devices Inc (ESD), a two-year-old design firm that in the past successfully launched a headphone-microphone splitter for the iPhone on Kickstarter. ESD also produce a small range of other smartphone accessories.
ESD co-founder James Flynn claims the Luxi “performs just as well as a number of expensive light meters” and the device will only set you back $24.95 (not counting the $649 for a new iPhone 5, but they assume you already have one). There is no indication that a Luxi-equipped iPhone will be able to measure flash intensity, so this gadget will be most useful to photographers using primarily continuous lighting.
