Another fascinating link - thanks Isaac. Beautiful, yes, often. Photography? Well, they are apparently made in a camera using film, so, end of story? The contrary argument would be based on the fact that they don't appear to depict objects in the external world but rather use a camera as a tool in what is essentially a printmaking process. Does it matter? No, mostly - yes only in the sense that accurate classification has some value in a curatorial context, or for eligibility to enter competitions.
