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 Photography1) 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 Photography1) 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.
