An illustrator is an artist who creates two-dimensional images for various companies and industries, such as fashion design, children's books, magazines, medical manuals, web sites, technical designs and advertising. The illustrator will use various techniques to create effects, like the simplicity of black and white, the richness of colour, or the use of light and shadows. Typically, an illustrator will choose to specialize in a certain industry according to their talents and work as a freelancer. If he or she excels in sketching clothing, becoming a fashion illustrator is a natural fit. If animals, foliage or earth formations are a strength, becoming a scientific illustrator would be a fit. Being a medical illustrator would require a talent in drawing human organs or the schematics of the human body or surgical procedures. An illustrator can also work for an advertising company, drawing images for labels, advertising materials or packaging. New illustrations are always needed for wrapping paper, greeting cards, books, magazine covers and advertising.
