The First Ever Photo Took 8 Hours to Expose!
Today, we take photos instantly with the tap of a button, but back in the early days of photography, things were very different. In fact, the first-ever photograph, captured by Joseph Nicéphore Niépce in 1826, took a whopping 8 hours to expose! Yes, you read that right—8 hours just to take a single image. Let’s take a look at this fascinating piece of history that paved the way for modern photography.
The first photo, called “View from the Window at Le Gras,” was taken by Joseph Nicéphore Niépce from a window in his house in France. To take this picture, he used a method called heliography. He covered a metal plate with a special substance called bitumen of Judea, which is a kind of asphalt. When sunlight hit the plate, the bitumen hardened where the light was the strongest. The parts that were in shadow stayed soft. After the exposure, Niépce washed the plate with a liquid to remove the soft bitumen, and what was left was a faint image of the buildings and landscape seen from his window.How the First Photograph Was Made
The long exposure time was due to the technology of the time. The chemicals used were not very sensitive to light, so it took several hours of direct sunlight for the image to form on the plate. Unlike today’s fast cameras, which can capture even moving objects in milliseconds, Niépce’s setup required a stationary subject and perfect lighting conditions for the hours-long exposure.Why Did It Take So Long?
The camera Niépce used was a camera obscura, an early version of what we now recognize as a camera, but without the film or digital sensors. The heliographic process was one of the earliest attempts to create a permanent photographic image, and although the resulting picture is very grainy and hard to see, it was groundbreaking at the time.Technical Details
While this first photo took 8 hours to expose, it wasn’t the last long exposure in early photography. Several years later, Louis Daguerre, another photography pioneer, managed to reduce the exposure time to around 10 minutes using a new process, but it still took years of innovation to reach the near-instant photography we have today.Fun Fact
