But the money is good, right?
It depends on your niche, and by extension, your price structure. If you want to develop your craft to the point that you can have an exclusive (IOW "highly paying) clientele, then you'll be fine. I'm talking photogs that charge anywhere from $5k-$10k and up. Become a PPA member and look at what some of the most successful photogs are doing.
Digital is both a blessing and a curse, because mostly anyone with a digital camera thinks that s(he) knows what they are doing... and they are underbidding the market. A lot of people expect jobs for either peanuts or free because "uncle Joe" has a digital and he can just snap away for free. And Sears offers complete portrait packages for $29.99 (or something like that).
If you're thinking about just becoming your local church's photog and just snapping away at a few events for your friends and even (gasp!) brothers and sisters in Christ, then either:
a) Ensure you are doing it for the Lord, and/or
b) Be prepared for LOTS of frustrations and the the continuous struggles to not let clients take advantage of you.
Whatever you do, do not, I repeat, do NOT let people take proofs w/o paying. And do NOT give your work away... you'll be surprised how greedy people get when what you do for them costs them nothing...
Ah! And always, ALWAYS, get a release so you can use your work for marketing purposes.
What you'll love the most is when you get all your expensive equipment on location, and when it's time to do formals people will step in right in front of you to take photos of your setups. And then the bride will not want to purchase your photos because "uncle Joe" has candids of all your setups... Of course, the photos won't be as technically refined as yours (there's more to photos than just snapping away and sending to Walgreens for processing), so they'll come back to you so you fix all the photos where the bride's dress looks green...
Photography is mostly a hobby for me these days. I am thinking on setting up a web page to do some poster sales, and I still do portraits every now and then. But I have learned to say "NO".
It's not impossible... so don't let my words discourage you. Weddings is just a game that I decided I'm not going to play. You'll have to do a few yourself to decide if that aspect of photography is up your alley. And if the Lord should open that door of opportunity for you, then rest assured that there is no man on this earth that can close it. It's better to follow your dreams and fail, than to never pursue them and then be sorry you never did.
(Edit) I forgot to add that weddings these days is primarily a team effort, so be sure you find one or two other folks you can team up with so all the possibilities at the wedding day are covered (at bride's home, pre-ceremony, ceremony, different angles, candids, reception, formals, etc). And find yourself a good lab.
