Just a thought, but might be worth dropping James a line, possibly requesting more definition in the "glossary",currently residing at the foot of the
page.My good lady often gets asked what levels she works to, even though it's specified on her profile,even some established photographers have varying opinions as to the various terms and explanations.I think it's important to note that the term "adult" maybe viewed as an "umbrella heading" under which several "sub genres" lie.
Whilst some may class topless and lingerie as adult rated, others may only view full frontal nudity,and male/female genitalia as falling into this category.
I was once pointed to a very conscise and well written article on a photographers website regarding such levels, if I can find the link, with James's conscent I'll gladly post it as a guide for those wanting an overview,
Regards Wayne.
