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.

Not accurate on Moto G6. Off by about 3 stops when compared to LunaPro SBC. But it can be calibrated to counteract the error. Incident seems to be fairly correct. Spot is erratic and slow to respond. At one point I moved the spot from light to dark area and the EV value went up! Too bad as the concept is good and the app is well designed from a usability standpoint. Too late to get my money back. The improve this app I would display all combinations of shutter speed and aperture simultaneously.

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

Please try the new version I just published, it allows you to pick between the sensors on your device to find the most sensitive. Thanks!

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...
