Almost exactly 10 years ago I got my first DSLR camera and one of the very first images I took was lightning during a massive thunderstorm.
After that I never had the chance again – until a few days ago. The rain was not too bad and the sight was ideal.

I suspect the many little black spots result from the combination of rain with the extremely bright flash. If there was a dust issue it would not be so evenly distributed and it only occurred in this one picture.
