What is Image

What Is Image


In common Usage, an Image or picture is an artifact that reproduces the likeness of some subject-usually a physical object or person.

An image may be two dimensional, such as a photograph, or three dimensional such as in a status. they
are typically Produced by optical devices --such as cameras, mirrors, lenses, telescopes, microscopes, etc. and natural object and phenomena, such as the human eye or water surfaces.

The word image is also used in the broader sense of any two-dimensional figure such as a map, a graph, a pie chart, or an abstract painting. In this wider sense, an image can also be produced manually,
such as by drawing, painting, carving, by computer graphics technology, or a combination of two, 
especially in a pseudo-photograph.

The volatile image is one that exists only for a short period of time. this may be a reflection of an object by a mirror, a projection of a camera obscura. or a scene displayed on a cathode ray tube. a fixed image, called a hard copy, is one that has been recorded on a material object, such as a paper 
or textile.

A mental image exists in an individual's mind: something one remembers or imagines. the subjects of an image need not be real; it may be an abstract concept, such as a graph, function, or "imaginary" entity. Forex, Sigmund Freud claimed to have dreamt purely in aural-images of dialogues. The development of synthetic acoustic technologies and the creation of sound art have led to a consideration of the possibilities of a sound-image comprised of irreducible phonic substance beyond linguistic or musicological analysis.
