Lightning Snap uses the sensor in your iPhone camera to detect an increase in brightness from lightning moving across the sky. The Lightning Snap can pick up a change in brightness in about 2ms and snaps a full resolution image.
The app is easy to use with a single slider to set the sensitivity of the detection.
- Exposure control
- Lock focus to distance
- Configurable delay from initial trigger for sky lighting
Tapping on the screen locks the focus and activates the lightning detection process. Tapping on the screen again unlocks the detection process. Full resolution images are stored to your photo library.
