I don't think the art of photography is in decline or the end is near or any of that. Not for an instant.
Those who remain committed to analogue / traditional processes will (I keep saying over and over!) be delighted to find that their work is valued more as time goes by. I see this very clearly.
Those who get involved with digital and hybrid processes will see more interesting and individual capabilities and a steady improvement in standards; we just have to remember that digital photography is still in its youth, relatively speaking, and still has quite a long way to go.
On both sides -analogue and digital- there are those people who bitch and moan and think things have gone to hell and the art is finished. Whatever. That's just a completely useless and de-motivating point of view. What these people want remains an enduring mystery. A warm bottle and a blankie? Whatever. Adapt or perish.
