Charles Harper Bennett
Charles Harper Bennett (born 1840 in London, died 1927 in Sydney) was an English photographic pioneer. He improved the gelatin silver process The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography r ... developed by Richard Leach Maddox, first in 1873 by a method of hardening the emulsion, making it more resistant to friction, and later in 1878 Bennett discovered that by prolonged heating the sensitivity of the emulsion could be greatly increased. This increased sensitivity resulting enabled shooting at 1/25 second, paving the way for the snapshot.

Gelatin Silver Process
The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image. A suspension of silver salts in gelatin is coated onto a support such as glass, flexible plastic or film, baryta paper, or resin-coated paper. These light-sensitive materials are stable under normal keeping conditions and are able to be exposed and processed even many years after their manufacture. The "dry plate" gelatin process was an improvement on the collodion wet-plate process dominant from the 1850s–1880s, which had to be exposed and developed immediately after coating. History Gelatine was used to copy the images of Daguerreotypes by 1845 and Alphonse Louis Poitevin wrote about positive proofs of negatives on dry gelatine plates in 1850. In the 1860s, the dry ...

Richard Leach Maddox
Richard Leach Maddox (4 August 1816 – 11 May 1902) was an English photographer and physician who invented lightweight gelatin negative dry plates for photography in 1871. Early life Richard Leach Maddox was born at Bath, England, on 4 August 1816. Photomicographic studies Long before his discovery of the dry gelatin photographic emulsion, Maddox was prominent in what was called photomicrography - photographing minute organisms under the microscope. The eminent photomicrographer of the day, Lionel S. Beale, included as a frontispiece images made by Maddox in his manual 'How to work with the Microscope' Invention of lightweight gelatin dry plates In photography, the Collodion process was invented in 1851 by Frederick Scott Archer. This invention required only two to three seconds of light Exposure (photography), exposure to produce an image, but plates had to be sensitized at the time of exposure, exposed while the emulsion was still wet, and processed immediately after ...
