Photographic developer - Development
The developer reduces the silver halides in the latent image in the exposed photograph into reduced, opaque, black silver metal. The image is then fixed using photographic fixer.
The mechanism by which this reduction occurs preferentially on those halide grains containing the silver atoms of the latent image is complex. The developer molecule (typical a relatively simple benzene-ring molecule) may act as an 'electron bridge'. (See www.kodak.com for more detailed discussion).
The time over which development takes place, and the type of developer, affect the relationship between the density of silver in the developed image and the quantity of light. This study is called sensitometry and was pioneered by F Hurter & V C Driffield in the late 1800s.

Sneak-Peek of Global Oneness Community
Hi friend! The Global Oneness Community, the place for information and sharing about Oneness is not really launched yet (you will see there is still some clean up to do) ...but it is now open for a sneak-peek! And if you wish - please register and become one of the very first members to do so! Jonas
