When I 1st learned photography, one of the guiding rules was to avoid including evidence of self in the image (eg, thumb on lens). But Lee Friedlander changed the rules by including some evidence of self. Cyndi Sherman expanded it to include only self in her work. Today's selfie includes the narcissism of Sherman and the evidence of being there (existence) of Friedlander. Now I suppose critics will have to invent new ArtSpeak in order to argue that the Selfie is art.
