Imaging

The act or process of creating an exact replica of the contents of a storage device, such as a hard disk, stored on a second storage device, such as a network server.

The capture of the images used:

• visible light the most common
• invisible light such as infrared, ultraviolet and x-rays
• ultrasound such as in ultrasound scanning
• magnetism such as in magnetic resonance imaging
• radar such as in navigation and satellite imaging

The storage of the images used:

• photographic film used to be most common
• digital media are now preferred due to ease of manipulation

The manipulation of the images used:

• optical techniques using film negatives and enlargers
• computer imaging / digital imaging manipulations are now more common due to its flexibility and versatility

The display of the images used:

• photographic papers
• colour printers such as ink jet, solid wax, dye sublimation and colour photocopy
