Image: Aesthetic, Functional, and Valuable
Image – The Concept
The word ‘image’ comes from the Latin word ‘imago.’ It refers to a picture that resembles an object, a living entity, or a scene. Broadly speaking, images may be created both, manually and digitally (with the use of latest computer based technology). Most of the manually created images include carvings, drawings, and paintings. On the computer, images can be generated using input devices and various creative software programs. The three most commonly used image file formats for scanning, internet, and printing use are JPG, GIF, and TIF.
Types of Images
Images can be two-dimensional (2-D) or three-dimensional (3-D). While 2-D images include screen displays, photographs, maps, graphs, and even abstract paintings, 3-D ones have an ‘illusion’ of depth in them. Applicable in videos, photos, and statues mostly, this effect is created by presenting a slightly different image to each eye. There are special software available in the market to create 3-D images. The various types of images include:
- Fixed – Also called as hard copy, it refers to a type of image, processed digitally, or photographed, and transferred on fabric or on paper.
- Volatile – This type of image has a temporary existence. It could be something as simple as a mirror reflection of an object or their display on a cathode ray tube.
- Moving – This refers to movies, videos, and animated display. Moving images are created with the help of a video camera that takes a series of photographs rapidly in the strips of film.
- Still – Referring to a non-moving, static image, this term implies the ‘non-mobile’ ones. Photographs are an excellent example of this type, where the images are captured through a device called camera. The medium of recording in a camera can be either a photographic film or digital memory. Digital images can be stored electronically and can be reproduced on paper as well.
- Mental – This type of image exists in the mind of an individual as either memory or imagination. It refers to the perception of an object, scene, or event not actually present for the senses. The subject in question may not even be real and may exist simply as an abstract concept. Sigmund Freud’s theories on human behavior are based on mental images.
Conclusion
Images have come a long way with the developments in technology. Graphic designing is now a full-fledged career option with scope in almost every field. Medicine, entertainment, engineering, designing, and animation – today images play an invaluable role everywhere, facilitating a fertile, growth-oriented future.
