In this photograph, Harry
Callahan transforms industrial telephone lines into a lyrical dance of
delicate, swinging lines. The abstraction seen in Callahan’s work has its roots
in early 20th-century experimental work by photographers of the Bauhaus in
Germany. By mid-century, this approach gained momentum on an international scale
through a movement called subjective
photography that sought to explore the power of images to communicate an
expressive view of reality.
