Camera Obscura


The name 'camera obscura' comes from the Latin words meaning 'darkened room'.  The first record of the camera obscura principle goes back to Ancient Greece, when Aristotle noticed how light passing through a small hole into a darkened room produces an image on the wall opposite, during a partial eclipse of the sun.  However, it may be much older than that.  Stone age man may have used the principle of the camera obscura to produce the world's first art in cave drawings.




Louis Daguerre (Louis Jacques Mande Daguerre) 

Born near Paris, France on November 18, 1789. A professional scene painter for the opera with an interest in lighting effects, Daguerre began experimenting with the effects of light upon translucent paintings in the 1820s.

Louis Daguerre regularly used a camera obscura as an aid to painting in perspective, and this led him think about ways to keep the image still.


In 1826, he discovered the work of Joseph Niepce, and in 1829 began a partnership with him.
He formed a partnership with Joseph Niepce to improve upon the photography process Niepce had invented. Niepce, who died in 1833, produced the first photographic image, however, Niepce's photographs quickly faded.

After several years of experimentation, Louis Daguerre developed a more convenient and effective method of photography, naming it after himself - the daguerreotype.

According to writer Robert Leggat, Louis Daguerre made an important discovery by accident. In 1835, he put an exposed plate in his chemical cupboard, and some days later found, to his surprise, that the latent image had developed. Daguerre eventually concluded that this was due to the presence of mercury vapour from a broken thermometer. This important discovery that a latent image could be developed made it possible to reduce the exposure time from some eight hours to thirty minutes.
Louis Daguerre introduced the daguerreotype process to the public on August 19, 1839 at a meeting of the French Academy of Sciences in Paris.
In 1839, Louis Daguerre and Niépce's son sold the rights for the daguerreotype to the French government and published a booklet describing the process.



Henry Fox Talbot

Fox Talbot reported his 'art of photogenic drawing' to the Royal Society. His process based the prints on paper that had been made light sensitive, rather than bitumen or copper-paper.

Fox Talbot went on to develop the three primary elements of photography: developing, fixing, and printing. Although simply exposing photographic paper to the light produced an image, it required extremely long exposure times. By accident, he discovered that there was an image after a very short exposure. Although he could not see it, he found he could chemically develop it into a useful negative. The image on this negative was then fixed with a chemical solution. This removed the light-sensitive silver and enabled the picture to be viewed in bright light. With the negative image, Fox Talbot realised he could repeat the process of printing from the negative. Consequently, his process could make any number of positive prints, unlike the Daguerreotypes. He called this the 'calotype' and patented the process in 1841. 


Kodak Brownie

In 1900, the Eastman Kodak Company introduced the Brownie camera.
The Brownie camera, simple enough for even children to use, was designed, priced, and marketed to have wide appeal. It made photography accessible to the masses.


The Brownie camera was a simple, black, rectangular box covered in imitation leather with nickeled fittings. 

To take a "snapshot," all one had to do was hold the camera waist height, aim, and turn a switch. Kodak claimed in its advertisements that the Brownie camera was "so simple they can easily be operated by any school boy or girl" 
The Brownie camera was very affordable, selling for only $1 each. 



Edward Curtis

Edward Curtis published The North American Indian between 1907 and 1930 with the intent to record traditional Indian traditional cultures. The work comprises twenty volumes of narrative text photogravure images.


Lewis Hine

Lewis Hine  was an American sociologist and photographer, Hine used his camera as a tool for social reform. His photographs were instrumental in changing the child labor lows in the United States


Eugene Atget

Eugene Atget was a French pioneer of documentary Photography, noted for his determination to document all of the architecture and street scenes Paris before their disappearance to modernisations.



Andre Kertesz


Andre Kertesez originally from Hungary bought his first camera and made his first photograph Budapest stock exchange in 1912 where he used to work as a clerk. He after moved to Paris and began a career as a freelance photographer. There the young transplant, speaking little French, took the street, wandering , observing and developing his intimate approach to image making.
From 1933 to 1936 Kertesz published three books of his own photographs. Immigrating to the United States in 1936, he settled in New York, where he earned his living photographing architecture and interiors for magazines such as House and Garden. It was not until he retired from commercial work at age sixty-eight taht Kertesz was free to focus again on the more personal subject that had delighted him as an amateur.






Henri Cartier Bresson



Henri Cartier Bresson was born on August 22, 1908 in Chanteloup, France. A pioneer in photojournalism.
Considered on of the major artists of the 20 th century, he covered many of the world biggest event from the Spanish Civil War to the French uprisings in 1968

For the rest of his life, in fact, Cartier-Bresson's approach to photography would remain much the same. He made clear his disdain for improved images, one that had been enhanced by artificial light, dark room effects, even cropping. The naturalist in Cartier-Bresson believed that all edits should be done when the image was made. His equipment load was often light: a 50mm lens and if he needed it, a longer 90mm lens.


Robert Frank


One of the most acclaimed photographers of the 20 th century , Robert Frank is best know for is seminal book The Americans, feauturing photographs taken by the artist in the mid-1950s as he travelled across the U.S.
These photographs feature sight of highway, cars , parades, jukeboxes, and diners as iconic  symbolsof America while simultaneously suggesting an underline sense of alienation and hardship.
In the 1950s, Frank was a regular contributor to Harper’s bazaar, but later turned his focus from still images to filmmaking , creating classic of American subculture such as Pull My daisy (1959)
