If woken by a tumultuous storm outside, most of us will wisely pull the covers over our heads and try to go back to sleep. For one plucky photographer though, it was the chance to dash outside and capture some truly electric images.

Frank Fennema from California made the trip from his home in Tiburon down to the Golden Gate Bridge. 'I woke up at 4.30am on Friday morning to the sound of thunder. I wondered how far off it was,' he said.

'I drove to the Marin Headlands but it was way too foggy so I went low near the Coast Guard station for this shot of the Golden Gate Bridge.

'I sat in my car with a remote shutter listening to podcasts. I had to wrap a poncho around my camera when the rain started.

'As the lightning struck I took lots of shots, this was about my fourth shot of the morning when I got lucky. You should of heard me say "YEEEESS!" when I saw the huge strike and the sky lit up white/blue with light.'

Mr Fennema's resulting images were somewhat spectacular, and perhaps worth the early morning start after all.
