Good quality app

First: disregard anyone that says you need to input a lens or sensor/film size, they don’t understand photography. The beauty of the aperture system is that at a 2.0, the same amount of light reaches the film plane whether the lens is a 20mm or a 200mm!

Second: this really is a great app, but in all of my tests, it is 1 stop underexposed. I checked this against several film camera meters, my Pentax K-1 full frame and my K3 apsc camera.

Knowing it is 1 Stop underexposed, I can use this with my old cameras that have no meter and get great results. If it calls for an aperture of f16, I use f11 and it’s spot on.

The best light meter app on the App Store!

I tried almost all the light meter apps on the AppStore and none of them even come close to this one. Most of them are too hard to use. This one does what I want, you select your film speed, then either shutter speed or aperture depending on the look you want, and it gives you the other value! You can even see what the camera is seeing to make sure you aren’t intentionally pointing it at the brightest part of the scene.

Those people who are complaining don’t know how to use a light meter or what this app is for. This is only for figuring out your exposure if your camera doesn’t have a light meter. Most digital cameras already have one built in. This is primarily if you have a film camera that doesn’t have a light meter or it doesn’t work anymore.

For me really useful

I returned to making photos with film a few months ago after having not since 80’s. I shouldn’t been but was surprised ate offering of ‘film’ apps in the phone world and particularly Lux. I’ve found it’s features, stability and accuracy for my needs to be on pun ‘spot’ on! The combination of iso/aperture/speed perfect and of late I’ve been putting a red gel over the camera similar to what I’m using on the film camera and have found the readings very reliable. Thank you for making this app freely available. If you have a donate page somewhere I would!
