Lightning shutter trigger 2.0 - another picture

flashYesterday, we got a thunderstorm. Usually, when people are on vacation, they prefer a nice weather. This is not the case for us Smile. We took the car, and drove to a place a few kilometers southwest of Ancelle, the small village where we are staying for a week, in south of french Alps.

Our flash detector triggered several times, but we got only two pictures. Only one displays a flash.

Conclusion: I'm happy with sensitivity of this version of the trigger Smile.

  • HTTP method
  • URI pattern
  • call definition
