Illustration

Illustration is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Illustration rather than just read about it. In short: An illustration is a decoration, interpretation, or visual explanation of a text, concept, or process, designed for integration in print and digitally published media, such as posters, flyers, magazines, books, teaching materials, animations, video games and films. An illustration is typically created by an illustrator.

Illustration — main illustration

Key takeaways

  • Illustration belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Illustration to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Illustration from memory before moving on to harder problems.

Reference excerpt

An illustration is a decoration, interpretation, or visual explanation of a text, concept, or process, designed for integration in print and digitally published media, such as posters, flyers, magazines, books, teaching materials, animations, video games and films. An illustration is typically created by an illustrator. Digital illustrations are often used to make websites and apps more user-friendly, such as the use of emojis to accompany digital type. Illustration also means providing an example; either in writing or in picture form. The origin of the word "illustration" is late Middle English (in the sense ‘illumination; spiritual or intellectual enlightenment’): via Old French from Latin illustratio(n-), from the verb illustrare.

Illustration styles

Contemporary illustration uses a wide range of styles and techniques, including drawing, painting, printmaking, collage, montage, digital design, multimedia, 3D modelling. Depending on the purpose, illustration may be expressive, stylised, realistic, or highly technical. Specialist areas include:

Architectural illustration Archaeological illustration Book illustration Botanical illustration Concept art Fashion illustration Information graphics Livre d'art Technical illustration Medical illustration Narrative illustration Picture books Scientific illustration

Technical and scientific illustration

Technical and scientific illustration communicates information of a technical or scientific nature. This may include exploded views, cutaways, fly-throughs, reconstructions, instructional images, component designs, diagrams. The aim is "to generate expressive images that effectively convey certain information via the visual channel to the human observer". Technical and scientific illustration is generally designed to describe or explain subjects to a nontechnical audience, so it must provide "an overall impression of what an object is or does, to enhance the viewer's interest and understanding." In contemporary illustration practice, 2D and 3D software are often used to create accurate representations that can be updated easily and reused in a variety of contexts. There is a Guild of Natural Science Illustrators and Association of Medical Illustrators. The Association of Medical Illustrators states that the median salary is $70,650, while for science illustrators it is $72,277. Types of jobs range from research institutes to museums to animation.

Illustration as fine art

In the art world, illustration has at times been considered of less importance than graphic design and fine art. Today, however, due in part to the growth of the graphic novel and video game industries, as well as increased use of illustration in magazines and other publications, illustration is now becoming a valued art form, capable of engaging a global market. Original illustration art has been known to attract high prices at auction. The US artist Norman Rockwell's painting "Breaking Home Ties" sold in a 2006 Sotheby's auction for US$15.4 million. Many other illustration genres are equally valued, with pinup artists such as Gil Elvgren and Alberto Vargas, for example, also attracting high prices.

History

Historically, the art of illustration is closely linked to the industrial processes of printing and publishing.

Early history The illustrations of medieval codices were known as illuminations, and were individually hand-drawn and painted. With the invention of the printing press during the 15th century, books became more widely distributed, and often illustrated with woodcuts. Some of the earliest illustrations come from the time of ancient Egypt (Khemet) often as hieroglyph. A classic example of illustrations exists from the time of The Tomb of Pharaoh Seti I, c. 1294 BC to 1279 BC, who was father of Ramses II, born 1303 BC. 1600s Japan saw the origination of Ukiyo-e, an influential illustration style characterised by expressive line, vivid colour and subtle tones, resulting from the ink-brushed wood block printing technique. Subjects included traditional folk tales, popular figures and everyday life. Hokusai's The Great Wave off Kanagawa is a famous image of the time. During the 16th and 17th centuries in Europe, the main reproduction processes for illustration were engraving and etching. In 18th Century England, a notable illustrator was William Blake (1757–1827), who used relief etching. By the early 19th century, the introduction of lithography substantially improved reproduction quality.

19th century In Europe, notable figures of the early 19th Century were John Leech, George Cruikshank, Dickens illustrator Hablot Knight Browne, and, in France, Honoré Daumier. All contributed to both satirical and "serious" publications. At this time, there was a great demand for caricature drawings encapsulating social mores, types and classes. The British humorous magazine Punch (1841–2002) built on the success of Cruikshank's Comic Almanac (1827–1840) and employed many well-regarded illustrators, including Sir John Tenniel, the Dalziel Brothers, and Georges du Maurier. Although all fine art trained, their reputations were gained primarily as illustrators. Historically, Punch was most influential in the 1840s and 1850s. The magazine was the first to use the term "cartoon" to describe a humorous illustration and its widespread use led to John Leech being known as the world's first "cartoonist". In common with similar magazines such as the Parisian Le Voleur, Punch realised good illustration sold as well as good text. With publication continuing into the 21st Century, Punch chronicles a gradual shift in popular illustration, from reliance on caricature to sophisticated topical observation.

Worked examples

Example 1 — a first encounter with Illustration

Start with the simplest possible case. Write down what Illustration claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Illustration before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Illustration ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Illustration

In research
Illustration appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Illustration in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Illustration is common in secondary-school and first-year university syllabi. It links to neighbouring topics Communication design, Design, Graphic design, so understanding it makes those chapters shorter.
In everyday life
Look for Illustration outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
