Photography

Changed peoples lives in the 19^th century
The camera obscura and other drawings had existed for several years but the photograph seems to only have taken some 50 years to develop from concept to presentation in 1839

Camera Obscura : People knew the principles of how photography got to work before it was created.The image could be processed on the wall or piece of paper. The camera obcura[ latin for dark room] was used to process pictures.
It was possibly invented around the 13th-14th century.

Camera obscurais essentially a dark closed space in the shape of a box with a hole on the side. The light coming through the hole transforms and creates an image on the surface that it meets like the wall of the box but upside down.

Photography wa only for profesionals or the rich till George Eastman started a company called Kodak in the1880s. He created a flexible roll film that did not require constand changing of solid plate.

He then developed a self contained box camera that held 100 exposures of film.
The customer would use this to take pictures, then send it back to the factory for the film to be developed. This was the first cheap camera the average person could afford, kind of like todays disposable camera.

 

According to a survey made by Kodak in 2007 when the majority of photography was already digital, 75 percent of professional photographers say they will continue to use film, even though some embrace digital.
The Photo marketing Association say that in the year 2000 nearly a billion rolls of film were sold each year and by 2011 a mere 20 million rolls, plus 31 million single-use cameras.
