Photography is the science, art, application, and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
Around the year 1800, British inventor Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance. He used paper or white leather treated with silver nitrate. Wedgwood succeeded in capturing the shadows of objects placed on the surface in direct sunlight however, his images would eventually darken all over.
The first permanent photoetching was an image produced in 1822 by the French inventor Nicephore Niepce, but it was destroyed in a later attempt to make a print of it. Niepce was successful again in 1825. Niepce’s camera required at least eight hours of exposure. He then partnered with Louis Daguerre, working on something more practical.
The daguerreotype process required a silver-plated surface sensitized by iodine vapor, developed by mercury vapor, and ‘fixed’ with hot saturated water. This process required mere minutes of exposure. Daguerre took the earliest known photograph of a person in 1838.
In 1876, Hurter and Driffield began working on the light sensitivity of photographic emulsions. The first transparent plastic roll of film was invented in 1889, nitrate film.
All these methods of photography, while incredibly important in preserving our history, left something to be desired…the color of the world. Today we have the capabilities of capturing these colors.
We can also recreate these photographs creating color where, before, there was only black and white.
