Photogram with Drinking Straw 

A photogram is a technique in which a small object is placed on paper and then it is exposed to light so an image of the object is captured on the paper. It was commonly used in experimental photography in the early 20th century. The technique was named by László Moholy-Nagy, an artist whose practice was focused on photography but also encompassed painting, design, and stage art.
Since the image is made directly from the object, it is often possible to guess the object by examining the shape and texture in the image. But more often the overall appearance of photograms is similar to abstract painting. Moholy-Nagy’s works, which possess both geometricity and softness, are reminiscent of the paintings of Wassily Kandinsky and Paul Klee, with whom he taught at the German art school Bauhaus.
