It means 'darkroom', the image is projected through a pinhole.
The image is inverted (Upside Down) due to refraction of light.
It is believed that it was invented by natural holes and letting light in the caves. -
Mo Ti (China) made the first description of the Camera Obscura
-
First to describe why and how a Camera Obscura works.
He is also the first to find out that the human eye works in the same way (Our eyes receive image 'upside down', but our brains turns them rightside up) -
Brightness and clarity of Camera Obscura improved by enlarging the hole and inserting a telescope lens
-
Camera Obscuras were more frequently used by artists to trace images and they were also made more portable, in the form of sedan chairs.
-
Professor J. Schulze accidentally made the first photosensitive compound by mixing chalk, nitric acid and silver in a flask. he noticed the flask darkening on side of flask exposed to sunlight.
-
Building on Professor J. Schulze's discovery, Thomas Wedgwood made the first photographic process called 'Sun Drawing'. This was made by painting the silver nitrate onto a piece leather, placing and object over the paint and setting it in the sun. This would leave the silhouette of the object on the leather. However this also faded quickly.
-
Joseph Niepce made the first permanent image, through a process he called heliography, which means Sun Drawing', it took over 8 hours to expose the image of a nearby rooftop
-
In 1837 Jacques Daguerre developed the process called Daguerreotyping. This was the first popular and common form of photography.
-
In 1839 Daguerre demonstrates his process to the public in Paris.
Images were exposed onto silver copper plates. It brought portraits to the masses and cost only 50 cents. Many portrait painters went out of business. -
In 1841, Fox Talbot patents a process he calls 'CALOTYPE' which creates permanent (negative) images using paper soaked in silver chloride and fixed with a salt solution.
Talbot created positive images by contact printing onto another sheet of paper. (This is how we make prints without pinhole camera) -
In 1888 George Eastman Kodak develops FILM, allawing photographers to have something lighter and more portable than metal or glass plates
-
In 1900 the Kodak Brownie is introduced as the first film camera. This is also the first camera made for regular people.
-
In 1975 Steven Sassone invented the first digital camera while working for Kodak. It weight 8 pounds and had 0.01 megapixels.
The process took 23 seconds, because the images were recorded in black and white unto cassette tape. -
In 2005 Digital Cameras sales eclipse the film camera sales. This is seen as the end of an era
-
In 2010 almost every phone has their own camera.
-
It is estimated that as of 2017 over 18 BILLION pictures are taken and uploaded unto the internet, as photography has become a common pass time with the rise of social media allowing people to upload and share their pictures and images
