Luxi incident light meter accessory for iPhone arrives on Kickstarter

Luxi incident light meter accessory for iPhone arrives on KickstarterThe Luxi incident light meter for iPhone has arrived on Kickstarter and is looking for funding to help it to get into mass production. The Luxi is a clip on accessory for your iPhone that when working alongside a companion app becomes a professional grade incident light meter which helps you to take awesome pictures with your DSLR camera.

Luxi is a small diffusion dome that fits securely over your iPhone’s front-facing camera. When attached and used with a light meter app, Luxi will help you determine the best settings for your DSLR or other camera so that you can take perfectly exposed pictures. With Luxi, your iPhone becomes a convenient and easy to use incident light meter. Professional light meters with the same features can cost several hundred dollars and require you to carry a whole separate device.

Incident light meters, like Luxi, measure the amount of light falling on the subject you are photographing, not the light reflected by the subject. Incident light meter readings are independent of the subject's reflectance and cannot be fooled by tricky lighting situations like back-lit subjects (e.g. sunset portraits).

The Luxi has been compared with many high end hand held light meters that cost hundreds of dollars and according to the developers, it stands up against them all with similar results. If you fancy picking one of these up as early as possible, should they make it into production; you can back the project through its Kickstarter page. Pledges starting from just $14 will get you one of the first off the line including free shipping across the U.S. The project is already over its rather small target of $10,000 and currently sits at just over $12,500 with 44 days of the campaign still to run.

Photographers, what do you think of the Luxi incident light meter for iPhone? Could you see yourself using a product like this?

Luxi incident light meter accessory for iPhone arrives on Kickstarter


Well I backed it. Could be a useful tool if it comes to fruition. I already use an Expodisc for this reason on my SLR, but that's more for custom white balance and using incident light to set it.

As a professional commercial photographer and having shot more than my fair share of portraits and weddings in years past, I can say I haven't personally used a light meter in years. Shooting RAW and tethered into Capture One or Lightroom and/or utilizing histogram readings in-camera affords the ability to calibrate and measure as you go. In the time it takes me to pull out the light meter, turn it on, confirm the settings and take the reading I can take a test shot and calibrate on the fly.
