Graphics (from Greek _gr. ; see
-graphy) are visualpresentations on some surface, such as a wall, canvas, computer screen, paper, or stone to brand, inform, illustrate, or entertain. Examples are photographs, drawings, Line Art, graphs, diagrams, typography, numbers, symbols, geometricdesigns, maps, engineering drawings, or other images. Graphics often combine text, illustration, and color. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flier, poster, web site, or book without any other element. Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style.
Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or an interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred.
The earliest graphics known to anthropologists studying prehistoric periods are
cave paintings and markings on boulders, bone, ivory, and antlers, which were created during the Upper Palaeolithicperiod from 40,000–10,000 B.C. or earlier. Many of these were found to record astronomical, seasonal, and chronological details. Some of the earliest graphics and drawings known to the modern world, from almost 6,000 years ago, are that of engraved stone tabletsand ceramic cylinder seals, marking the beginning of the historic periods and the keeping of records for accounting and inventory purposes. Records from Egypt predate these and papyruswas used by the Egyptians as a material on which to plan the building of pyramids; they also used slabs of limestoneand wood. From 600–250 BC, the Greeks played a major role in geometry. They used graphics to represent their mathematical theories such as the Circle Theoremand the Pythagorean theorem.
In art, "graphics" is often used to distinguish work in a monotone and made up of lines, as opposed to
Drawing generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface. Common tools are
graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, pastels, and markers. Digital tools which simulate the effects of these are also used. The main techniques used in drawing are line drawing, hatching, crosshatching, random hatching, scribbling, stippling, blending, and shading.
Drawing is generally considered distinct from
painting, in which colored pigments are suspended in a liquid medium and are usually applied with a brush. Notable great drawers include Michelangelo, Rembrandt, Raphaeland Leonardo da Vinci.
Many people choose drawing as a main art style, or they may use it to make sketches for paintings, sculptures and other types of art.
Woodblock printing, including images is first seen in Chinaafter paperwas invented (about A.D. 105). In the West t5he main technioques have been woodcut, engravingand etching, but there are many others.
Etching is an
intagliomethod of printmakingin which the image is incised into the surface of a metal plate using an acid. The acid eats the metal, leaving behind roughened areas, or, if the surface exposed to the acid is very thin, burning a line into the plate. The use of the process in printmaking is believed to have been invented by Daniel Hopfer(circa 1470–1536) of Augsburg, Germany, who decorated armour in this way. Etching is also used in the manufacturing of printed circuit boards and semiconductor devices.
Line art is a rather non-specific term sometimes used for any image that consists of distinct straight and curved lines placed against a (usually plain) background, without gradations in shade (darkness) or
hue( color) to represent two-dimensional or three-dimensional objects. Line art is usually monochromatic, although lines may be of different colors.
An illustration is a
visualisationsuch as a drawing, painting, photographor other work of artthat stresses subject more than form. The aim of an illustration is to elucidate or decorate a story, poem or piece of textual information (such as a newspaperarticle), traditionally by providing a visual representation of something described in the text. The editorial cartoon, also known as a political cartoon, is an illustration containing a political or social message.
Illustrations can be used to display a wide range of subject matter and serve a variety of functions, such as:
* giving faces to characters in a story
* displaying a number of examples of an item described in an academic textbook (e.g. A
* visualising step-wise sets of instructions in a technical manual
* communicating subtle thematic tone in a narrative
* linking brands to the ideas of human expression, individuality and creativity
* making a reader laugh or smile
* for fun (to make laugh) funny
A graph or chart is a type of
information graphicthat represents tabular, numeric data. Charts are often used to make it easier to understand large quantities of data and the relationships between different parts of the data.
A diagram is a simplified and structured visual representation of concepts, ideas, constructions, relations, statistical data, etc, used to visualize and clarify the topic.
A symbol, in its basic sense, is a conventional representation of a
conceptor quantity; i.e., an idea, object, concept, quality, etc. In more psychological and philosophical terms, all concepts are symbolic in nature, and representations for these concepts are simply token artifacts that are allegoricalto (but do not directly codify) a symbolic meaning, or symbolism.
A map is a simplified depiction of a
space, a navigational aid which highlights relations between objects within that space. Usually, a map is a two-dimensional, geometrically accurate representation of a three-dimensional space.
One of the first 'modern' maps was made by
One difference between photography and other forms of graphics is that a photographer, in principle, just records a single moment in reality, with seemingly no interpretation. However, a photographer can choose the
field of viewand angle, and may also use other techniques, such as various lenses to distort the view or filters to change the colours. In recent times, digital photographyhas opened the way to an infinite number of fast, but strong, manipulations. Even in the early days of photography, there was controversy over photographs of enacted scenes that were presented as 'real life' (especially in war photography, where it can be very difficult to record the original events). Shifting the viewer's eyes ever so slightly with simple pinpricks in the negative could have a dramatic effect.
The choice of the field of view can have a strong effect, effectively 'censoring out' other parts of the scene, accomplished by cropping them out or simply not including them in the photograph. This even touches on the philosophical question of what reality is. The human brain processes information based on previous experience, making us see what we want to see or what we were taught to see. Photography does the same, although the photographer interprets the scene for their viewer.
An engineering drawing is a type of
drawingthat is technical in nature, used to fully and clearly define requirements for engineered items. It is usually created in accordance with standardized conventions for layout, nomenclature, interpretation, appearance (such as typefaces and line styles), size, etc.
There are two types of computer graphics:
raster graphics, where each pixel is separately defined (as in a digital photograph), and vector graphics, where mathematical formulas are used to draw lines and shapes, which are then interpreted at the viewer's end to produce the graphic. Using vectors results in infinitely sharp graphics and often smaller files, but, when complex, vectors take time to render and may have larger filesizes than a raster equivalent.
In 1950, the first computer-driven display was attached to MIT's
Whirlwind Icomputer to generate simple pictures. This was followed by MIT's TX-0and TX-2, interactive computing which increased interest in computer graphics during the late 1950s. In 1962, Ivan Sutherlandinvented Sketchpad, an innovative program that influenced alternative forms of interaction with computers.
In the mid-1960s, large computer graphics research projects were begun at
MIT, General Motors, Bell Labs, and Lockheed Corporation. Douglas T. Rossof MITdeveloped an advanced compiler language for graphics programming. " S.A.Coons", also at MIT, and J. C. Fergusonat Boeing, began work in sculptured surfaces. GM developed their DAC-1system, and other companies, such as Douglas, Lockheed, and McDonnell, also made significant developments. In 1968, ray tracingwas invented by Apple
During the late 1970s,
personal computersbecame more powerful, capable of drawing both basic and complex shapes and designs. In the 1980s, artists and graphic designers began to see the personal computer, particularly the Commodore Amigaand Macintosh, as a serious design tool, one that could save time and draw more accurately than other methods. 3D computer graphicsbecame possible in the late 1980s with the powerful SGI computers, which were later used to create some of the first fully computer-generated short films at Pixar. The Macintosh remains one of the most popular tools for computer graphics in graphic design studios and businesses.
Modern computer systems, dating from the 1980s and onwards, often use a
graphical user interface(GUI) to present data and information with symbols, icons and pictures, rather than text. Graphics are one of the five key elements of multimediatechnology. 3D graphicsbecame more popular in the 1990s in gaming, multimediaand animation. In 1996, Quake, one of the first fully 3D games, was released. In 1995, Toy Story, the first full-length computer-generated animation film, was released in cinemas worldwide. Since then, computer graphics have become more accurate and detailed, due to more advanced computers and better 3D modelling software applications, such as Maya (software), 3D Studio Max, Cinema 4D.
Another use of computer graphics is
screensavers, originally intended to preventing the layout of much-used GUIs from 'burning into' the computer screen. They have since evolved into true pieces of art, their practical purpose obsolete; modern screens are not susceptible to suchburn in artifacts.
In the 1990s, Internet speeds increased, and Internet browsers capable of viewing images were released, the first being Mosaic. Websites began to use the GIF format to display small graphics, such as banners, advertisements and navigation buttons, on web pages. Modern
web browsers can now display JPEG, PNG and increasingly, SVG images in addition to GIFs on web pages. SVG, and to some extent VML, support in some modern web browsers have made it possible to display vector graphicsthat are clear at any size. Plugins expand the web browser functions to display animated, interactive and 3-D graphics contained within file formats such as SWFand X3D.
Modern web graphics can be made with software such as
Adobe Photoshop, the GIMP, or Corel Paint Shop Pro. Users of Microsoft Windowshave MS Paint, which many find to be lacking in features.
Numerous platforms and websites have been created to cater to web graphics artists and to host their communities. A growing number of people use create internet forum signatures—generally appearing after a user's post—and other digital artwork, such as photo manipulations and large graphics.
visualelements often used to point readers and viewers to particular information. They are also used to supplement text in an effort to aid readers in their understanding of a particular concept or make the concept more clear or interesting. Popular magazines, such as "TIME", "Wired" and " Newsweek", usually contain graphic material in abundance to attract readers, unlike the majority of scholarly journals. In computing, they are used to create a graphical interface for the user; and graphics are one of the five key elements of multimediatechnology. Graphics are among the primary ways of advertising the sale of goods or services.
Graphics are commonly used in
businessand economicsto create financial charts and tables. The term "Business Graphics" came into use in the late 1970s, when personal computers became capable of drawing graphs and charts instead of using a tabular format. Business Graphics can be used to highlight changes over a period of time.
Advertising is one of the most profitable uses of graphics; artists often do advertising work or take advertising potential into account when creating art, to increase the chances of selling the artwork.
The use of graphics for overtly political purposes—cartoons, graffiti, poster art, flag design, etc—is a centuries old practice which thrives today in every part of the world. The
Northern Irish muralsare one such example.
Graphics are heavily used in
textbooks, especially those concerning subjects such as geography, scienceand mathematics, in order to illustrate theories and concepts, such as the human anatomy. Diagrams are also used to label photographs and pictures. Educational animationis an important emerging field of graphics. Animated graphics have obvious advantages over static graphics when explaining subject matter that changes over time.
The "Oxford Illustrated Dictionary" uses graphics and technical illustrations to make reading material more interesting and easier to understand. In an
encyclopedia, graphics are used to illustrate concepts and show examples of the particular topic being discussed.
In order for a graphic to function effectively as an educational aid, the learner must be able to interpret it successfully. This interpretative capacity is one aspect of
Film and animation
Computer graphics are often used in the majority of new feature films, especially those with a large budget. Films that heavily use computer graphics include
Lord of the Ringstrilogy, the Harry Potterfilms, Spider-Man and War of the Worlds.
The majority of schools, colleges and universities around the world educate students on the subject of graphics and art.
The subject is taught in a broad variety of ways, each course teaching its own distinctive balance of craft skills and intellectual response to the client's needs.
Some graphics courses prioritize traditional craft skills—drawing, printmaking and typography—over modern craft skills. Other courses may place an emphasis on teaching digital craft skills. Still other courses may downplay the crafts entirely, concentrating on training students to generate novel intellectual responses that engage with the brief. Despite these apparent differences in training and curriculum, the staff and students on any of these courses will generally consider themselves to be graphic designers.
pedagogyof a graphic design (or graphic communication, visual communication, graphic arts or any number of synonymouscourse titles) will be broadly based on the teaching models developed in the Bauhausschool in Germany or Vkhutemasin Russia. The teaching model will tend to expose students to a variety of craft skills (currently everything from drawing to motion capture), combined with an effort to engage the student with the world of visual culture.
Famous graphic designers
Aldus Manutiusdesigned the first Italic typestyle which is often used in desktop publishingand graphic design. April Greimanis known for her influential posterdesign. Paul Randis well known as a design pioneer for designing many popular corporate logos, including the logo for IBM, NeXTand UPS. William Caslon, during the mid-18th century, designed many typefaces, including "ITC Founder's Caslon", "ITC Founder's Caslon Ornaments", "Caslon Graphique", "ITC Caslon No. 224", "Caslon Old Face" and "Big Caslon".
