Black & White Photography

The first camera photography was invented in the 1820s, before that time, people  really defines black and white or monochrome photography? The tone between the dark shadows and the light define black and white photography. It is important to note that there are some images that are not purely black and white or monochromic. However, they both employ the same principle. Such images include the blue tone images that used cyanotype process and the brown tone that used the albumen process. They were used more than 140 years ago. 

The first successful black and white images were taken by Joseph Nicephore Niepce a French developer. However, it got destroyed as the attempted to make copies of it. He was again successful in 1825, where he managed to produce a black and white image of a window.
