An illustration is an elucidated graphical representation of any given concept or written material in the form of a sketch, picture, photograph, or any other artwork. Traditionally, illustrations were created using ink and paper, but these days, illustrations are made using various computer software packages. The benefit of creating illustrations using computer graphic software is that it can be created in both two dimension and three dimensions. However, the question remains that why illustrations are created and needed. Below are what Illustrators Do.

Convey the right message

Illustrations help convey the right message easily and effectively. If you want to express a concept, which otherwise is difficult to explain or describe, illustrations are largely used. The brain of a human being is developed in such a way that it easily grasps graphic representation than any other form of information; hence, illustrations are easily and effectively able to convey the right message. Furthermore, people with hearing disability can also understand the message intended by illustrations.

Advertising and marketing

Advertising and marketing play a crucial role in promoting business products and services. However, these days, no one will remember the brand or care much about television commercials. For such situations, 3D illustration plays a pivotal role to promote brand awareness. As said in the previous point, the human brain has the tendency to grasps and remembers any graphical representation; hence, when they are out in the market looking for something, they will easily be able to recollect an illustrated brand.


Since the beginning, illustrations are largely used for education.Children start to understand the world around them with the help of illustrated pictures depicted in their elementary books. Illustrations not only help children understand the world around them, but it also plays a big role in developing their imagination. This is the reason why books with good illustrations are preferable for elementary education. These days, with the availability of a computer, created illustrations, they are even used in higher studies like engineering, architect, mechanical, and so on, to make complex theories seem easy.

Illustrated mascot design

To be used in marketing campaigns in place of photography to display a lifestyle scene or to very precisely convey a concept related to the brand – concepts cannot always be accurately conveyed when using ‘stock art’ or ‘stock photography’ which force one to seek out a design that almost matches your concept… but ‘almost matches’ may not be as effective in your marketing campaigns as a fully matched concept.

Commissioning an illustration service for diagrams and technical drawings; providing a more user-friendly environment, and reducing customer confusion. This is when an illustration service is used to convey complex ideas or detailed processes and use illustrative design to simplify them.

Not every design agency can offer an in-house illustration service, and those that do (including freelance illustrators) are usually unable to do so at competitive pricing without holding onto copyright.

Aside for the above purposes, businesses and companies also use 3D illustrations to advertise themselves on the internet. It is a fact the people spent most of their time on the internet and considering this fact, 3D illustrated advertisement on the internet could prove to be beneficial. When compared to another form of internet advertising like videos and photographs, illustrated advertising is far more effective.

Some of the benefits of such advertisement are:

1. It loads quickly compared to a video clip or photograph

2. It is less expensive than video advertising

3. It can describe more information than a simple photograph

4. It can be modified or customised easily

The importance of illustration lies in the fact that it can complement any writing clearly in lesser lines or drawings. The readers get a better understanding of what is provided in the context, and they need not even have to read the content. Illustration plays a great role in advertising or promoting products for a company wherein the illustrator creates the images of the products to the right audience in the most attractive way.

The viewers will get attracted to the illustration more than the contents, and people who are impatient of reading the advertisement can easily get to know about the product and its features through the illustrations provided with it. A professional illustrator knows very well to add the realistic touch to matter most simply and accurately. Medical illustrations help patients and other readers to understand the illustration easily if at all the contents is not digestible to them.
