I was in that boat. I started shooting my kids, then their school and social functions. I would give the host or teacher a cd with the photos on it. I started getting comments about how I should go into business as my photos were so good. I found a photo certification course at our local community college and took it-not for the certification because now-a-days, that doesn't mean much. The info that I came away with (settings, hands-on experiences, photoshop techs, etc) were what I wanted.
I entered contests like our local paper, magazines, online contests, State Fair, etc. I've had my photos displayed all over the state. All of it was fun, and no pressure. Then I went to work for a local youth sports photo company. I got paid to do photo shoots of my friends, birthday parties, etc. It stopped being fun and I put a lot of pressure on myself to produce lots of good photos. I took a break and went back to doing the fun stuff (my kids, school yearbook shots, a photo trip to the Galapagos with
National Geographic) and have gotten back into it again.
I thought about going to work for a chain photo studio, mainly to get the experience. Then I read reviews by employees and was turned off. It's not about taking the photos, it's about pushing the sales, which is not my style. Maybe I will bite the bullet and deal with it for a year.
I see you live in PCB. We visit there every summer and I love shooting down there! I especially love going over to St Andrews and catching the wildlife along the shores. I even got some shots of the Obama's in the bay last summer! Many of the shots I entered in contests were done in PCB. I thought about having a family portrait done by one of the hundreds of photographers there, but trying to pick one.....that's a problem. That's were making yourself stand out and marketing with a unique twist comes into play. I see them advertised in all the tourist books. I see their work hanging in shops, etc. But to me, they all look the same. When I find the one that does something different that I like, that will be the one I use. I don't know how to describe it, other than I will know when I see it.
So like the others have said-find a class to learn all you can about photography. Get out and just shoot away, playing with all the settings until you know them in your sleep. Find someone to work along with, even if it means putting up with the bad things. That's where you'll learn the most probably-the what-not-to-dos. Then come up with a marketing angle that makes you different from all the others in your area (and you have a lot of competition down there)! Most importantly, have fun because once that is gone, so is the passion!
