There are two different definitions of "media" in artwork. "Media," as the plural for "medium," refers to the type of material used by an artist to create his artwork. "Media" can also refer to substances added to paint to create a desired texture or effect, according to ArtinCanada.com.
Any material can be considered a medium for art, because there are no limits or rules to the types of materials that artists can use for their work. Traditional paint media include acrylic paint, watercolors and oil paint. Drawing media include graphite pencils, oil pastels and markers. Traditional sculpture materials include wood, clay and stone, although any object can be used for three-dimensional artwork. Examples of medium additives are substances that are mixed into paint for a glossy finish or sandy texture.
