Photography Types

Daguerreotype:
The daguerreotype was the first successful process of photography. It was invented around 1837 by Louis-Jacques-Mande-Daguerre. The invention was announced on August 19, 1839 at a meeting of the French Academy of Sciences in Paris. By 1850, there were 70+ daguerreotype studios in New York City alone.
 The daguerreotype is a direct-positive process, creating a highly detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative. You’ve got to be careful. The silver-plated copper plate had first to be cleaned and polished. Next the plate was sensitized in a closed box over iodine until it took on a yellow-rose appearance. The plate, held in a lightproof holder, was then transferred to the camera. After exposure to light, the plate was developed over hot mercury until an image appeared. To fix the image, the plate was immersed in a solution of sodium thiosulfate or salt and then toned with gold chloride.




Polaroid:
The instant camera id a type of camera that makes a developed film image. Credit was given to an American scientist called Edwin Land and was first announced in 1948, a year after unveiling instant film in New York City.  The earliest instant camera was invented in 1923 by Samuel Shlafrock.

 

 

 

 

Digital:

A digital camera (also known as digicam) is a camera that captures video or still photographs by recording images on an electronic image sensor. Most cameras sold in our world today are digital and digital cameras are used in our everyday uses from mobile phones to iPods. Steven Sasson as an engineer at Eastman Kodak invented and built the first digital camera using a charge-coupled-device image sensor in 1975.

At its most basic level, this is all there is to a digital camera. It has a series of lenses that focus light to create an image of a scene. Instead of focusing this light onto a piece of film, it focuses it onto a semiconductor device that records light electronically. Computers then break this electronic information down to digital data.
