Important photography moments


Louis Daguerre and the Daguerreotype


French painter and physicist Louis Daguerre partnered with Niépce in an effort to reduce the excessive exposure time needed to render an image



based on the use of light sensitive paper as opposed to metal plates. Talbot would eventually — and accidentally — discover that a short exposure time and the right chemicals turned his paper into a negative that could be used to make multiple positive prints. Talbot called his process “calotype”

Roger Fenton: War Photographer


Originally recognized for his architecture and landscape photography, Fenton was dispatched to cover the Crimean War in 1855, thus becoming the world’s first war photographer. Because of the unwieldy nature of his equipment and its inherent technological limitations, Fenton was unable to photograph moving subjects and instead focused on posed portraits and landscapes. He chose not to photograph dead or injured soldiers.

Crossing the Niagara


William England, chief photographer with the London Stereoscopic Company, gathered with 5000 other spectators to watch Jean Francois Gravelet (performing under the name Charles Blondin) attempt to cross from Canada to the United States by walking a tightrope suspended above the Niagara River.

The Roll Standard


George Eastman transparent roll film made of nitrocellulose. Later that year, Thomas Edison took Eastman’s 70mm Kodak film roll, slit it down the middle, and cut transport perforations down both sides

Stark Realism


Reinhold Thiele is often cited among the founders of photojournalism, having covered major events in Britain including the opening of the Tower Bridge and Queen Victoria’s Diamond Jubilee. In 1899, the London Daily Graphic commissioned Thiele to cover the Second Boer War.

Joseph Nicéphore Niépce’s Very Long Exposure


e 8 hour exposure was then washed with a mixture of oil of lavender and white petroleum, rendering a view of the surrounding buildings, courtyard, and at least one tree, as seen from Niépce’s upstairs bedroom. He called his process “heliography.”

Instant Gratification


In 1947, American physicist Dr. Edwin Land invented a one-step process for developing and printing photos by applying the principle of diffusion transfer, which reproduces the image captured by the camera’s lens onto a photosensitive surface serving as both film and photo
