Callahan, whose career spanned fifty years, was experimental in his method, whether with camera size, making multiple exposures, high-contrast prints and using both black and white and colour film. Another common theme in his work was the use of reflection. Particularly when taking photos through a shop window, the reflections would create a patchwork and collage-like effect, bringing a unique level of visual intrigue to Callahan's work.
