The meters measure illumination in terms of luxes or foot candles are known as lux meters or light meters.
Lux meter light meter diagram.
This value does not correlate to an objective value of energy radiated or reflected as different wavelengths within the visible spectrum are perceived with varying sensitivity by the eye and lux meters evaluate light intensity in consideration of this variable.
We have to measure light in many tasks.
Speed of 1 8000s to 60s f1 to f90 aperture sensitivity from 25 to 819200 iso.
Handy if the light sensor is located on the front side of the device.
Range of incident light measurement iso 100.
What is lux meter.
Lux or foot candle minimum and maximum values diagram with average value adjustable sensor sensitivity.
To measure the light accurately a lux meter is a very suitable device.
Lux meter is a simple light meter for measuring illuminances lux fc by using the light sensor of the device.
The application only works if your device has a light sensor.
Lux meters sometimes called light meters measure the intensity of illumination as distinguished by the human eye.
For this the lux meter should be used.

Exposure compensation usage of nd filters is possible.
It may differ from real illuminance and between different devices.
Double tap the screen to save the current lux value.
Saves maximum and minimum lux values calibration multiplier supports both luxes and foot candles be aware that the accuracy of the light.
Lux meter is a simple light meter for measuring illuminances lux fc by using the light sensor of your android device.
The measured values depend on the accuracy of your light sensor.
