In my first visit to the Hanckok Tower I had the luck of that a thunderstorm take place at the north of the Lake Michigan. I had my Nikon F3 so I set it at AP mode with the lens full close, and leave the camera at the handrail
really like it. what makes it different is that the ligtning is actually quite a small part of the image. I like that as it gives the sky a truly epic scale and a far greater sense of space.
