Matiz was born in the small village of Aracataca in the Magdalena Department of Colombia to father Tulio Matiz and mother Eva Matiz. His hometown is also the birthplace of Gabriel Garcia Marquez. He travelled widely and sold caricatures and illustrations to earn a living. In 1951, Matiz's gallery hosted the first exhibition of Colombian artist Fernando Botero with a showing of his paintings at the Bogotá gallery.
Matiz was known for his sense of style including a thick slightly long hair, colored jackets, and gangster style mustache. He had a robust laugh and carried his caricatures and drawings in a folder. He was at the center of the bohemian intellectualism of Bogotá, Caracas, Mexico City and other Latin American capital centers.
He photographed Frida Kahlo, Diego Rivera, Esther Williams, Janice Logan, David Alfaro Siqueiros, the first castings of María Félix, Luis Buñuel, Marc Chagall, Louis Armstrong, Álvaro Mutis, Pablo Neruda, Walt Disney, Enrique Santos Montejo, “Calibán”, Lucho Bermúdez, Agustín Lara, Gabriel Figueroa, Esther Fernandez, José Clemente Orozco, Mario Moreno Cantinflas, and Dolores del Río.
He was influenced by Mexican cinema, geography, architecture, history, muralism, and history as well as the artists Gustave Doré, George Grozt, Nadar and Guadalupe Posada. He was a photographer for Asi, Life, Reader's Digest, Harper Magazine, Look and Norte. He had a high profile and intense dispute with David Alfaro Siqueiros.
