Taken on a D3100. Took several photos and combined the best. Originally, I had 10 photos in one image, but decided it was too much and didn't help the composition. I settled on three separate images creating the final product. I did mask around the smaller bolts to avoid the city lights from overlapping at different points, and used a screen opacity in order to not block the other bolts of lightning. Then used a black and white adjustment layer to adjust.
