You know what, I think that all along through the evolution of Photography, all of its aspects from boiling mercury and ten minute exposures, to the Kodak Brownie [the first camera to be widely available] to 35mm SLR's, to the first flash bulbs, then tubes, first colour films, negative and positive, and formats getting smaller and smaller and the arrays of developers and processes that came and went... to all those things you mentioned Nick. At all those major steps, and major innovations in the field... someone out there felt the same way you do.
I mean, I can just imagine being a photographer who was used to shooting 8x10 traditionally in studio, with the rigour and skill required. And then see the emergence of 6x7 film and photographers shooting with it, doing similar things. You know, I'm sure he must have thought, "Well, that's it... photography is dead now."
But I think the reality could possibly be [and mind me, I probably have no clue what I am talking about here] that the human race is quite good at adapting and pushing things. Transportation is transportation, whether on foot, on horseback, in car, on airplane, spaceship, teleport doorways [I am hoping for this one] it will always still be transportation. Getting someone from one place to the next.
So maybe the future of photography is going to be a little different, but to me, it's still going to be photography.
[and I really, really, really hope that it still will be Photography otherwise I'm out of a career I haven't really started yet]
