Drie jongemannen in de kamer van Hendrik Herman van den Berg before 1894

This photograph, by Hendrik Herman van den Berg, captures three young men in a room, likely in the early 20th century, using the then-novel technique of magnesium flash. Magnesium flash photography, popular at the time for its ability to capture images indoors, involved igniting magnesium powder to create a bright burst of light. The process was cumbersome, requiring careful measurement and handling of the powder, often in a tray or lamp, to create a brief, intense illumination. It's material properties allowed photographers to venture into dark spaces, revealing scenes previously unseen with such clarity. The soft, diffused light, characteristic of magnesium flash, lends the scene a slightly surreal quality. The technology itself speaks to an era of rapid industrialization and the rise of consumer culture. It democratized image-making, making it accessible for personal documentation and artistic expression, while changing our perception of space and time. So, next time you come across an early photograph, consider the chemistry and mechanics that made it possible. This image is a testament to the transformative power of materials, and the intersection of science, art, and society.
