Wolk en bliksemschichten boven huizen before 1908

This black and white photograph, taken before 1908, captures a cloud and forked lightning by renowned British astronomer Sir Norman Lockyer (1836-1920). Part of his research into the nature of dark flashes of lightning, the image shows a cloud and forked lightning in the sky, illuminating the silhouette of houses in the background. This photographic illustration was originally published as part of a larger work exploring the relationship between photography and scientific inquiry.
