Photo Theory
Capture - Reflected light from an object passes into a camera and then onto a light surface
Process - Captured image is turned into something we can see
Store - The image is put onto something we can keep such as a printed photograph
Analogue Photography
1) Light enters camera through lens
2) Light hits light sensitive film and reacts
3) Film removed from camera and is turned into a negative image
4) Negative projected onto photographic paper using chemicals
Digital Photography
1) Light enters camera through lens and hits light sensitive sensor
2) Signal from sensor converted into a digital data by a processor
3)Digital data stored as an image on a storage medium in the camera
USB - Is a physical connection used by the cameras and scanners. This is possibly the fastest option.
Removable card - Images can be captured by a digital device onto a removable card
WiFi - Some cameras use WiFi technology to send images to a computer
RAW - RAW image files have not been processed by the cameras. They can be printed or edited with computer imaging software. A computer can correct RAW files more successfully than those that have been processed by the camera. However, RAW files are very large and not all software can edit them.
JPEG - When an image is turned inro a JPEG, quality is sacrificed for a reduction in the size of the file - consequently this is known as a 'lossy' process.
Bitmapped graphic format (.BMP) - Used internally by Microsoft Windows system
PICT (.PCT) - Used on Apple Mac's as digital file format
Tagged image file format (.TIF) - Store high colour image
Photoshop doc (.PSD) - Edit digital images in Adobe photoshop
Graphics interchange format (.GIF) - Widespread use on the internet
JPEG - Good for online use.

Intro
Photo journalism is the idea of using an image to tell the story of any event visually instead of the written word. It gives people a more definite insight to an event because they can see it from themselves and make their own interpretation instead of being more or less told what to think from words. A picture is a fair representation of what has happenend in an event which gives people something to base their views on that hasn't be tampered with to create a false sense of judgement. One person that changed the face of photo journalism was Henri Cartier Bresson. He used his imagination and creativity to capture visual moments that he thought would be dectrimental to other people. He knew that he could get the idea of his work across to other people so they could see whats around them and make their own clear judgement of a picture. His technique of photography was envied by many as he was always at the right place at the right time to capture these shots.
To do this, he used one of the first cameras that became available at that time. The camera was publically realeased in the late 1920's. It was used to capture pictures from world war 2 and showed people what the war was like and gave them a chance to interpret what they were seeing.
