Lightning

I am learning how to photograph storms and fireworks.
Here is my first decent photo of lightning. This was taken using a Nikon D-70 with a 3 second exposure using a circular polarised filter. I have since learnt that this is not the correct way to do it, but I still think it looks pretty good. These strikes hit simultaneously. The camera was sitting on my desk (no tripod at that time!) pointing from my place at Arcadia Vale, slightly to the south east of Wangi Wangi.
