I don't see why we can't discuss technical issues with regard to portraiture is this area of the forum, and I think it will prove useful as we build an archive of information in this genre. Doesn't mean some things won't apply to other genres of photography, but it focuses the discussion nicely for those, like myself, who may be attempting to improve their portraits. (There's always room for improvement, it seems... )

And framing some of the "how's" of the conversations to the "why's" of the conversation can serve to foster a creative and inspiring atmosphere. After all, sometimes you see the image in your head, and even understand why you want to make it ... but can't quite find the "how to make it... ". This strikes me as the perfect place for both questions.

And yes... definitions can meander with photography...
