Shot at Toronto's Centre Island. A great example of being in the right place at the right time. My sister and I went to the Island after work for some photos and this amazing sunset started to form, so I quickly put the camera on a tripod and started shooting intervals (using the Pclix) for about an hour hoping to capture the lightning. I have 5 lightning shots out of around 600 photos and this is the best one.
