Product Description

Luxi For All is a diffusion dome attachment for your mobile device's front-facing camera. When paired with the Luxi app for iOS, Luxi For All will help you determine the best settings for your DSLR or other camera, so you can take perfectly exposed pictures. It's just like one of those fancy old-school light meters, but way more affordable. And because it works with the gadget you already have in your pocket, it's way more convenient!

APPLICATIONS FOR IOS DEVICES:

  • Luxi is the official app developed by Makers4Good for iPhone, iPod Touch and iPad. Its feature set is appropriate for the great majority of users, and is the recommended starting point. Users with advanced and/or domain-specific needs may want to look at one of the other applications listed below.
  • Pocket Light Meter is a third-party app which has many of the same features as our Luxi app, but also adds a few advanced features--such as footcandle readings--which might be useful to lighting designers, scientists, and the like.
  • Cine Meter II, also developed by a third party, is the app you're looking for if you're a videographer or DP. It is designed specifically for cinematography, and has many very useful features for that usage: shutter-prioritization, neutral density settings, a waveform monitor...and now, color metering! (note: color metering feature requires iOS 8.0 or greater)

Why do I need it?

The light meter built into cameras measures reflected light. A reflected light meter shows an appropriate setting for an average of the whole scene. If you are taking a picture of a scene that does has neither an average, nor internally consistent lighting situation, your camera's built-in light meter will not be accurate. Usually, that 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 For All.

Will it work with my device?

Luxi For All builds upon the design of the original Luxi to bring convenient, inexpensive light metering to everybody who owns a mobile device. While the original Luxi was designed specifically for iPhone, Luxi For All will fit onto all of your iOS devices: iPhone, iPod Touch, iPad...you name it. Even if your device is inside a case!

How accurate is it?

In our testing of Luxi For All and in our experience with the original Luxi attachment, we have found the readings provided by iPhone apps paired with our devices to be highly comparable to readings taken with those old-school purpose-built light meters. The following picture shows a Luxi For All side-by-side with a relatively low-end Minolta Auto Meter IV F handheld light meter under even lighting conditions.
