I was always under the impression that a person looking for admission to an art program of some sort didn't need to already be a great artist, or what would be the point of the program? How do we measure potential? Flashy portfolios would suggest to me that someone could skip the art school entirely, and just get out there and hustle the business side of it.
Macshroomer makes some good points, although I wouldn't quite be as grim about the prospects of making money in the photographic arts as he is. But, definitely the business side of it is where the difference lies between a good amateur and a pro. Just understand the market of the area of photography you are primarily interested in, and be realistic about your own personality fit within that world. When I was photo editing for a small newspaper group in Portland I brought in a high school kid to string for me, especially in the high school sports area. He was eager, I gave him all the film he needed, went through the editing process with him, gave him free reign on our computers/scanners... and paid him for every shot we published - which was great motivation. The money wasn't much, but this kid was always looking for work, so it was easy to give him a chance, since he was also very receptive to guidance about what we were looking for. After a while, I began giving him some news assignments. I was able to actually trim my staff of a couple of lazy part-timers who never showed up unless I called them for an assignment. Long story short: After he graduated from high school he got his first job with a small paper and doing free lance. He got to know all the other photojournalists in the metro area, and made good business contacts and relationships. After three years, he decided he wanted to actually make real money, so he quit and started his own business. Now he does freelance magazine shoots, has his sports shots picked up by AP, USAToday, SportsIllustrated, gets calls from many business magazines... and all that's on the side. His portrait studio and wedding business has leaped into the stratosphere.
He is fully into the "linked-in" concept of social networking, where his clients become his friends on Facebook, and all the new business it generates through referrals is amazing. He "tweets" about almost all his assignments as he's doing them, which posts to his blog, and all the 'followers' of his endeavors just blows my mind sometimes... everyone seems interested in what he's up to. Lots of photographers now see him as a guru (due to his workshops and visibility) and he's only 30. Now he gets jobs in several states, does weddings in Mexico, Europe (Italy next month) and of course locally. He has figured the business side of things out. He has taken a totally creative approach to senior pictures, corporate portraits and weddings, including video. He's at almost every Blazer home basketball game.
On top of that, he conducts photo workshops several times a year geared to pro photographers wanting to enhance their business. He gets guest speakers from the wide world of photojournalism, freelance, manufacturers reps, product demos, lighting/portraiture workshops... website current trends and what most photographers are doing wrong in that regard... just lots of stuff he shares. He is now one of the best known photographers in our area, and even on a national level by those who count - the ones who pay for services. What he told me was that the reason he went into business for himself was because he really wanted to "work" less, and although he's busier than ever, he controls his own life and mixes fun and work. It just doesn't seem like he's working, to hear him say it.
It is all about taking it seriously as a business, if that's what you want to do professionally. You still have to be good at your art, but that just isn't enough to go pro.
But, anyone can do it. It's like any other entrepreneurial enterprise. The opportunities are there, you just have to have the right ambition and maybe personality to make it happen.
PS: I have several other stories of regular guys I know who are full-time professional photographers, either employed or in business for themselves, none of whom majored in anything related to photography while in college, if they went at all. All for another time, but an interesting subject for anyone who really wants to know how others broke into the business...
