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.

A closer crop for lightning detail.

UPDATE: My 3rd book; daily dose of imagery - vol 3 is available now. You can order directly from my blurb page or from my books page. Either way blurb will ship the books directly, the sooner you order the better chance you have to get it in time before end of the year. (you'll notice a small increase in price, and it's because blurb is offering premium paper now which is better and heavier stock.
