The common portrait is a figurative painting, drawing, photograph, engraving, or sculpture of a person, displaying a face or a head and shoulders. Before the beginning of the modern art movements, the purpose of the traditional portrait was to depict the exact features of the subject (a person).
However, painting a royal family, King, queen, or a group of prominent people was also considered part of the portrait types!
Various modern methods and techniques in the portrait have been used since the emergence of modern art in the late 19th century. Each artist executed their work, figurative or non-figurative, according to the personal vision or the movement style; Pablo Picasso and Amedeo Modigliani's portraits are the best examples of modern art portraits.
The image: Three portraits were made of acrylic on canvas by artist Amer Hanna Fatuhi. The artist executed these artworks using different techniques and styles.
