Whilst I wouldn't go quite as far as Wilky, there is an important point here.
It's easy to over-analyse a picture, looking too closely at the technical photographic aspects of it and in so doing, well, completely missing the point of the picture.
I recently spent some time in the Julia Margaret Cameron gallery on the Isle of Wight. Because her work is so early, the technical aspects are obviously quite poor by modern standards, but keep on looking and after a while a certain magic starts to dawn. Her work is incredibly beautiful.
Many of Henri Cartier Bresson's photographs wouldn't necessarily stand up to modern technical scrutiny for their focus, but that doesn't prevent his work from being truly wonderful.
Obviously it's not pictures of babies being born but I'm sure you get what I mean.
