This is a light meter — it needs a phone or tablet camera to read the scene.
Open this page on your phone or tablet:
Once open, add it to your home screen to use it like an app.
Tap the ISO, shutter, aperture or ND tile on the main screen to pin it to a value — the remaining settings are then solved around it.
Applies to live camera readings only. Compare against a trusted meter or your drone's own exposure preview. Positive = this meter reads scenes as brighter. On a clear sunny day, a front-lit scene should read close to EV 15.
Use this if you continued without the camera earlier, or if the live reading stopped.
180° (shutter = 1/(2×fps)) gives natural motion blur and is the default for cinematic footage.
Dronetjenesten Lightmeter measures scene brightness with your device camera and computes exposure for the selected drone camera. Readings are estimates — confirm with your drone's histogram/zebras.
