▯ Precisionism: painting and photography movements Painting: inspired by French Paul Saison (did a lot with shapes) and cubism (new ideas of angles and planes) o Not a formal group, no manifesto, but a group of like-minded people o Called cubist realists Photography: Charles Sheeler (he did painting and photography and sometimes copied his photographs into paintings) o Interested in forms and shapes and largely contact printing, printed it directly on paper to get a precise, clear, sharp detail in (diff. techniques + traits from painting but the idea is the same) o Cubism influence (emphasis on geometry and plane) but the
