Final answer:
During the Renaissance, artists developed various techniques to achieve greater naturalism in their paintings. These techniques include the use of realistic proportions, foreshortening, sfumato, chiaroscuro, and linear perspective.
Step-by-step explanation:
Renaissance painting was developed in 15th century Florence when artists began to reject the flatness of Gothic painting and strive toward greater naturalism. Many important techniques were developed during this time, including the use of realistic proportions, foreshortening, sfumato, and chiaroscuro. Linear perspective, the use of parallel lines to create the illusion of depth, was also a major artistic technique developed during the Renaissance.
