Drawing involves using dry media like pencil and charcoal or wet media like ink to portray objects through lines and textures. There are four main printmaking processes - relief, intaglio, lithography, and screen printing. Photography captures optical images on light-sensitive surfaces. Sculpture can be two or three-dimensional and involves processes like modeling, carving, casting, and assembly. Architecture developed from post and lintel construction to modern methods using steel, concrete, and lightweight systems.
