I'm an engineer by trade, and a photographer by hobby. In the fall of 2007, I bought my first digital SLR, a Nikon D40x, and haven't looked back yet. The majority of my photographic expeditions involve abandoned structures in Western Pennsylvania, but I'm never without my camera while on the road or at a Pirates game, and I have been known to take the occasional photo of a plant.
