Thank your for your votes. I am Rick from Spring Hill, FL. I shot this after the rain over a football field that offered a great view of the sky. I used a Nikon D3100, ISO 100, f8 with a 30 second exposure in raw mode. I converted it to B&W, used a black filter, vivid filter, exposure, & contrast adjustments to enhance the lightning and darken the clouds giving the appearance that the lightning was shooting out of the clouds into the black sky. You can see more of my work at my website below.
