An illustration is a visualization or a depiction of a subject made by an artist, such as a drawing, sketch, painting, photograph, cinema or other kind of image of things seen, remembered or imagined, using a graphical representation. The word comes from the latin word illustra'tio, illu'stro meaning enlighten, irradiate. Printing is the current process for reproducing illustrations, typically with ink on paper using a printing press. Illustrations can be artistic images illustrating for example a text, poem, fashion, magazines, stamps or abook and very often illustrations were made for children's books. The aim of an illustration is to elucidate or decorate a story, poem or piece of textual information by providing a visual representation of something described in the text. Illustrations can also represent scientific images of flora, medicine or different processes, a biological or chemical processes or technical illustrations to give information on how to use something.[1] Illustrations can be executed in different techniques, like watercolor, gouache, ink, oil, charcoal chalk or woodcut.
