My Camera Obscura
Steps to creating a Camera Obscura;
1. Cut out 2 centimetre square at the end of the cardboard box.
2.Leave the other end of the box open so that you can stick the tracing paper.
3.Cut a piece of tracing paper (13cm by 13cm, with a 1cm border on the inside).
4. Stick the tracing paper on the open side (make sure it is not loose or else your image will not be very clear).
5. Put a magnifying glass on the 2 centimetre square that you cut out (this is to make the image clear).
6.Place your camera obscura to an image and it will project it to the tracing paper upside down.

Camera Obscura
A camera obscura is a darkened box with a convex lens or aperture for projecting the image of an external object on to a screen.
Alzahen
Alzahen is the Arabian scientist who invented the camera obscura. Renaissance artists used the camera obscura.
Johann Heinrich Schultz
Schultz is best known for his discovery that the darkening in sunlight of various substances mixed with silver nitrate is due to light, not the heat as other experimenters believed, and for using the phenomenon to temporarily capture shadows.
Joseph Nicephore Niepce
Joseph Nicephore Niepce had become fascinated with the printing method of lithography, in which images drawn on stone could be reproduced using oil-based ink. Searching for other ways to produce images, Niepce set up a device called a camera obscura, which captured and projected scenes illuminated by sunlight, and trained it on the view outside his studio window in eastern France. The scene was cast on a treated pewter paper that after many hours retained a crude copy of the buildings and rooftops outside. The result was the fist known permanent photograph.
Henry Fox Talbot
Henry Fox Talbot was an English scientist, inventor and photography pioneer who invented the salted paper and calotype processes, precursors to photographic processes of the later 19th and 20th centuries. Calotype or talbotype is an early photographic process introduces in 1844 using paper coated with silver iodide.
Louis Daguerre
In collaboration with Joceph Nicephore niepce Louis Daguerre invented the first practical photographic process, which was widely used in portraiture until the mid 1850s.
George Eastman
In 1880 he perfected a process of making dry plates for photography and organised the Eastman Dry Plate and Film company for their manufacture. The first kodak (a name he coined) camera was placed on the market in 1888. It was a simple handle box camera containing a 100-exposure roll of film that used paper negatives.

SLR Camera
SLR stands for single lens reflex. A SLR camera is a camera that typically uses a mirror and prism system (hence 'reflex' from the mirrors reflection) that permits the photographer to view through the lens and see exactly what will be captured. When the shutter button is pressed on a SLR, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.

Aperture
Aperture is a hole within a lens, through which light travels into the camera body. The larger the hole, the more light passes to the camera sensor. Aperture also controls the depth of field, which is the portion of a scene that appears to be sharp. If the aperture is large, the depth of field is small. In photography, aperture is typically expressed in ''f'' numbers.

Shutter Speed
Shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open whilst taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.
Philippe Halsman
Philippe Halsman (1906-1979) was born in Riga Latvia and begun his photographic career in Paris. In 1934 he opened a portrait studio in Montparnasse, where he photographed many well-known artists and writers. Halsman's photographs of politicians, celebrities and intellectuals were featured widely seen in magazines like LIFE and Vogue. His more famous subjects included the likes of Marc Chagall, Le Corbusier, Audrey Hepburn and Albert Einstein. He also had a 37-year collaboration with Salvador Dali, which resulted in several famous surrealist series including the ''Dali's Mustache'' portraits. In the 1950s, Halsman began asking his sitters to jump in front of camera, because he noticed that doing so paradoxically seemed to relax people. In all of Halsman's 'jump' images, his intentions were for people to reveal their ambition or lack of it, their self-importance or their insecurity.
