That's interesting but I think some talents are required. That's the essence that allows you reflect on yourself and your works and your own motivations. That's the essence that forces you to push yourself to become better than your last works. Come on, we all know there are people who just won't become better photographers even if they have 2 decades to devote in the art. Hehehehehe... What is considered a better photographer? I mean....there is no break thru in their artistic development. Works they produced few years ago are the same as they are producing now. If the works were bad back then, they are bad now also.
Yes there are a lot of people that really are not creative and do not know how to nurture creativity but it can be nurtured and I personally know examples of that. But one problem is so many really have nothing to say and if they do they are either using the wrong medium or just haven't figured out how to say it. They can't push passed the obvious. Many are just happy if they can get things in focus and half way exposed properly. Those are usually the people that are just interested in taking photographs of their families. There is absolutely nothing wrong with that and most will never be the visionary that Sally Mann is and was when she photographed her family or Abelardo Morell and the family work that he did.
I think when one is really starting to arive is when people look at their work and they know it is theirs before they see the signature or who made the image. That usually comes from some kind of conscious effort on the photographers part. In first seeing trends in the way he/she sees naturally. The way he/she composes. The way they process and that all becomes a personal way of seeing. That is not easy. Most never get to this point. And this might not be important in maybe another thread but here we are talking art. I think in almost all art we always see a little of the creator. Roy DeCarava one said "You should be able to look at me and see my work. You should be able to look at my work and see me".
All of those things can be nurtured in the right environments. The problem sometimes becomes over time, and I see it a lot in forum land, is there is some horizontal visual growth but not a lot of vertical growth or even a lot of encouragement in that direction.
The book I mentioned earlier in this thread by Betty Edwards is a great place to start better understanding the creative process.
