I find it absolutely riveting... even though I am fiercely heterosexual, I am cannot help but find beauty and seduction in the representation of the vulva (I sometimes prefer to call it the cunt. A vulva is too coldly anatomical.)
Like me, Nick had to recruit willing models, explain the aim of the project, get them to disrobe and open their legs wide apart to expose their most intimate body parts to his close scrutiny. You can easliy imagine that this situation is heavily sexually loaded...
Nick sells posters and his book "Petals" on his website on http://nickkarras.com/Book.php
"Nick Karras has brought a refined aesthetic sensibility to the forty-eight black & white photographs of the most sacred part of a woman's body. The female form has been forever the subject of the visual arts of sculpture and painting. Photography brings the hard challenges of realism. Karras achieves an exquisite balance between an expression of art and the natural delicacy of a woman's vulva."
