Throughout the 1950s and 1960s, Bacon's work continued to evolve, often reflecting portraits of his friends, including Lucien Frued and Frank Auerback. He also began using photography within his process in order to avoid judgement from sitters' on his distortion of them, a problem he faced in his earlier works. Over the course of the 1960s, Bacon's work took a clear shift from less gruesome and dark imagery towards twisted portraits that incorporated a variety of colours.
Bacon flourished during this period, meeting with a variety of influential artists, such as Alberto Giacometti and John Deakin, as well as producing a large number of paintings. It was during this era that he began experimenting heavily with matierality, often using imprints from corduroy and other fabrics or squeezing paint directly from the tube onto the canvas. These works demonstrated a freedom and passion for his practice through their variety of emotions, whether that took a playful or frightening result.
It was during this stage of his life that Bacon met George Dyer. Dyer would become a huge influence on Bacon's artistic career and his personal life. A large number of paintings from this period depict Dyer as the subject, demonstrating his continued reverance for him. The two began a turbulent relationship in the early 60s which was reflected in Bacon's paintings during their time together, as well as in his memorial paintings after Dyer's death in the 1970s.
