An art model poses for any visual artist as part of the creative process, providing a visual reference for the human figure in a work of art.

However, more than being simply the subject of art, models are often thought of as muses, a source of inspiration without whom the art would not exist.

The most common types of art works that use models are figure drawing, figure painting, sculpture and photography, but almost any medium may be used.

Art models are often paid professionals with skill and experience but are rarely employed full-time, and artists may also rely on friends and family to pose.

Paid art models are usually anonymous and unacknowledged subjects of the work.

Models are most frequently employed for art classes or by informal groups of artists that gather to share the expense of a model.

Models are also employed privately by professional artists.

Although commercial motives dominate over aesthetics in illustration, its artwork commonly employs models.

For example, Norman Rockwell used his friends and neighbors as models for both his commercial and fine art work.

An individual who is having their own portrait painted or sculpted is usually called a "sitter" rather than a model, since they are paying to have the work done rather than being paid to pose.

Web design encompasses many different skills and disciplines in the production and maintenance of websites.

The different areas of web design include web graphic design; interface design; authoring, including standardised code and proprietary software; user experience design; and search engine optimization.

Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all.

The term web design is normally used to describe the design process relating to the front-end (client side) design of a website including writing mark up.

Web design partially overlaps web engineering in the broader scope of web development.

Web designers are expected to have an awareness of usability and if their role involves creating mark up then they are also expected to be up to date with web accessibility guidelines.

A website is a collection of related web pages, including multimedia content, typically identified with a common domain name, and published on at least one web server.

A website may be accessible via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by referencing a uniform resource locator (URL) that identifies the site.

An electronic portfolio (also known as an eportfolio, e-portfolio, digital portfolio, or online portfolio) is a collection of electronic evidence assembled and managed by a user, usually on the Web.

Such electronic evidence may include input text, electronic files, images, multimedia, blog entries, and hyperlinks.

E-portfolios are both demonstrations of the user's abilities and platforms for self-expression.

If they are online, users can maintain them dynamically over time.

Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
