Luxi - iPhone Incident Light Meter Adapter

If you are taking a picture of a scene that does not have an average lighting situation, your camera's built-in light meter will not be accurate and causes an overexposed or underexposed picture. Sunset portraits and other pictures with strong back-lighting are common situations, and can be aided by using an incident light meter like Luxi. Luxi is a small patent-pending diffusion dome that fits securely over your iPhone’s front-facing camera and transforms your iPhone into a convenient and easy to use incident light meter. Unlike regular cameras that measures reflected light, Luxi measure the amount of light falling on the subject you are photographing.

Luxi is designed to work just like a professional incident light meter which can capture light from a 180° angle. When using a light meter app without Luxi, the iPhone camera only receives light from a limited angle which means it doesn't capture all the light. This will produce readings that are both inconsistent and inaccurate. Readings taken with Luxi can be entered directly into your DSLR or any camera with manual override capability.
