I had been out photographing the whole day, and just as I called it quits and returned back to the hotel. It started rumbling in the distance, I wasn't quite sure on where the thunderstorm was and I soon gave up trying to find a good spot to photograph it, and returned to my hotel.
But as it turned out, the best view of the thunderstorm was from the balcony on the hotel I was staying in, which of course was totally awesome.
First I made a HDR photo, for the foreground of the town and the church tower, the clouds and the mountains. Then I made some long exposures i order to capture the lightning.
In post i started out by making the HDR, like I normally do. This one is made in HDREfex Pro 2 from Nik.
Then I masked in the lighting from two of the long exposures, containing the two best caught lighting strikes.
