Use your phone as a light meter for your analog camera!

You like using your old film camera but it doesn't have a built-in light meter?
The built-in meter is broken or requires special batteries?

Use Luxilux in aperture priority mode (Av) by choosing the ISO and aperture, and Luxilux will calculate the right shutter speed to get a proper exposure.

Use it in shutter priority mode (Tv) by choosing the ISO and the shutter speed, and Luxilux will calculate the right aperture to get a proper exposure.

Manual mode (M) lets you change all values and shows you how much they differ from the calculated optimal exposure.

You can choose between full stops, half stops or third stops for ISO, aperture and shutter speed.

Specify the area for the meter reading even more accurately by zooming in or out. 
If your device has two or three back cameras, you can switch between them.

A Delightful Light Meter App

The Luxilux Light Meter app truly is a masterpiece of an app. It, quite elegantly, displays all the necessary information that one would need in properly adjusting their Camera for the perfect shot. Unlike other light meter apps on the App Store, this app doesn’t have any gimmicky, unnecessary visuals that don’t enhance or add to the user’s experience, but rather tasteful choices in displaying certain information, such as the aperture, or the shutter speed, where these informations are neatly and uniformly displayed to the user. Additionally, the developer has a fantastic no data collected privacy policy, which adds to the value of this reasonably priced app. Overall, a fantastic light meter app that makes setting up your camera a delightful breeze.

Great Light Meter!

This is a great light meter for my film/analog camera! It seems very accurate, and I like the UI.

Note: it does not take pictures, but that is as intended as this is just a meter for getting the correct exposure for your film camera.

I would love the capability to save certain lenses and their specific apertures in a future update, but the app works exactly as intended.

Thank you for your review and the feature request!

So amazingly cool

I had my grandpa’s old camera and light meter for years, and having something like this really brings back the feel of artistry and craft to taking a photograph.

Forget pre-calibrated photos and everything happening in the background. Manual and analog are the only ways to go if you want to be a craftsman/craftswoman.
