What is a photograph?

I was having the debate today of what will happen to the concept of photography. In the past photography was about capturing a moment in time. Maybe tweaked here and there, but essentially a moment in time, in order to create an emotional response. Yet with the days of photoshop, and also the advent of video on all cameras, what will become the role of photography? I see black & white photos becoming a dying breed. And now the concept of actually capturing the act is becoming less and less so...For example, this NY Times article talking about a photo contest won by photoshop creations. I respect what you can do in Photoshop, but it implies a different sort of creativity. Less about framing what you do see versus creating a new world. The creativity in these Photoshop pictures is likely more impressive and requires seeing something that is not necessarily there. Perhaps it is akin to taking a photo in black & white, you have to see it in your mind, not on the camera...(at least in the old days)
