In searching for a link to reference this particular photographic genre, I found this at a serious photographer's blog;
'While there are many great bodies of work employing this method, there is also a lot of crap. Let’s be honest, for people who have no real conceptual thinking in their work, the typology can become an easy trick. It gives work the illusion of cohesion and intellectual rigor.'
Well, that's me stuffed then.
In fact it was a very interesting post, I loved the year on year series of photos by Nicholas Nixon of his wife and her sisters that she drew my attention to.
(PS - As Fantastic Forrest pointed out in comments, the above link is to a general overview of Nixon's work, including the portrayals of AIDS sufferers. '25 years of the Brown sisters' his photos of his wife and her sisters, is shown here.)
I seem to be linking a lot lately. There's so much good stuff to be found...
(The posts might be worth enlarging...)
