Answer to What is This on the Cover of American Laboratory September

The September cover of American Laboratory depicts soap film, specifically a soap solution of dish soap, glycerine, sugar, and water. The solution was suspended in a two-inch metal ring below a piece of white foam matboard. The camera, a Canon 5D Mark II equipped with a 65-mm macro lens, was placed above the matboard and viewed the soap film through a hole in the board. A flash was directed onto the white surface and uniformly illuminated the soap film. The angle between the vertical axis of the camera and plane of the soap film was adjusted so that the color reflected from the light appeared in the photograph.
