Light Meter

About this app

A reflected light meter with spot metering (using the device's camera) and an incident light meter (using the device's light sensor) in one app. Tested accurate against Gossen and Sekonic meters on most devices.

Can be used for any type of camera from film SLR to pinhole to cinematographic.

In addition to the two meters, the app includes a Color Temperature (White Balance) meter, a Reciprocity Calculator, an Exposure Convert, a Manual (Sunny Sixteen) calculator, a Depth of Field calculator, and an EXIF Reader.

Ratings and reviews

I think it's a pretty good app. I've shot about 10 rolls of film using it and very rarely had exposure issues. I'm knocking off a point because the camera sensor is the most used app and in the top right corner. if you could sort apps I would give it 5 stars. I have a taller phone (S24 ultra) and have to use two hands to get to the camera sensor as is.

App worked well after one photoshoot and it stopped functioning. The sensor feature stopped functioning after a single photoshoot (that's the function that I purchased the app for). I uninstall and reinstall the app to no avail. When it worked it was very accurate and it gave me great exposure settings. Oh, well you get what you pay for. **Response: it's just not reading

Lots of functionality, but not sure of the accuracy. I compared it with a Gossen Luna Pro with the adapters from CRIS Camera, my old manual SLR with a Wein cell, and a Gossen Luna Pro SBC with a 9v battery. The camera and both the Luna Pros were within 1/2 stop every time, but this app was always off by over a stop or more. In the end, it always comes down to seeing how your camera shoots with the settings the meter suggests, then adjusting accordingly...
