Jo Hammar (sometimes credited as Jo Hammer) is a former erotic photographer born in Germany. He is noted for being one of the early adopters in the mainstream of many of the studio effects and production values in so-called underground photgraphy and films that he directed.
A self-professed "People photographer", Hammar dismisses the label of being a so-called "fetish photographer". However, he has published two specific fetish collections entitled "Fetish Rubber" and "Female Rubber" which have sold well to the public.
While Hammar is still an active photographer of various topics, including erotic and fetish, he does not release as much fetish-specific product as he once did. He prefers to remain mostly in more mainstream productions today.
