Looking at what is widely considered these days a "good or great photograph" it's tough to imagine competing with it. HDR has taken over the world of "successful" photography, shiny crap is the game to own or else.
When I see so-called TOP fashion photographers, at least one of them being Polish, I cringe, my brain swells, I see smoke escaping through my ears. How has the World ever made it t to this stage of visual "appreciation". The successful garbage is what it is and to be successful, one needs to compete with it. Sadly some great photographs, and photographers along with them, are drowned by the fake sameness.
I don't doubt there are still those who managed to break through the standardized wisdom of visual evaluation, make a name for themselves, and found a way to make a living. There is some interest in film based weddings, although that is just a bleep rather than a viable business option in a sustainable way (shooting the rich aside).
All in all, it never hurts to try, but I feel most who want to enter photography as a business, need to be either true believers in what sells, or lower own aesthetic values in order to make it.
In all of above I am not referring to those who don't know the difference, are mediocre in every way, and somehow make money in photography.
