Richter resettled from Düsseldorf to Cologne, where he still lives and works today. In 1996, he moved into a studio designed by architect Thiess Marwede. Art Photo-paintings and the "blur" Richter created various painting pictures from black-and-white photographs during the 1960s and early 1970s, basing them on a variety of sources: newspapers and books, sometimes incorporating their captions, (as in Helga Matura (1966)); private snapshots; aerial views of towns and mountains, (Cityscape Madrid (1968) and Alps (1968)); seascapes (1969–70); and a large multipart work made for the German Pavilion in the 1972 Venice Biennale. For Forty-eight Portraits (1971–72), he chose mainly the faces of composers such as Gustav Mahler and Jean Sibelius, and of writers such as H. G. Wells and Franz Kafka. From around 1964, Richter made a number of portraits of dealers, collectors, artists and others connected with his immediate professional circle. Richter's two portraits of Betty, his daughter, were made in 1977 and 1988 respectively; the three portraits titled IG were made in 1993 and depict the artist's second wife, Isa Genzken. Lesende (1994) portrays Sabine Moritz, whom Richter married in 1995, shown absorbed in the pages of a magazine. Many of his realist paintings reflect on the history of Nazism, creating paintings of family members who had been members, as well as victims, of the Nazi party. From 1966, as well as those given to him by others, Richter began using photographs he had taken as the basis for portraits. In 1975, on the occasion of a show in Düsseldorf, Gilbert & George commissioned Richter to make a portrait of them. Richter began making prints in 1965. He was most active before 1974, only completing sporadic projects since that time. In the period 1965–1974, Richter made most of his prints (more than 100), of the same or similar subjects in his paintings. He has explored a variety of photographic printmaking processes – screenprint, photolithography, and collotype – in search of inexpensive mediums that would lend a "non-art" appearance to his work. He stopped working in print media in 1974, and began painting from photographs he took himself. While elements of landscape painting appeared initially in Richter's work early on in his career in 1963, the artist began his independent series of landscapes in 1968 after his first vacation, an excursion that landed him besotted with the terrain of Corsica. Landscapes have since emerged as an independent
