I started taking photos of some friends with a point and shoot, and then editing them in Photoshop. That was about 6.5 years ago, then I got a digital SLR camera and read a TON about SLR photography online, and also did a couple of shadowing/apprenticeships with some talented, established photogs.
Every time I took a photo that I really liked, I posted it on facebook and people started commenting. Then--I did some weddings for friends to increase my portfolio, and the more I put out there for people to see, and the more I read and practiced my skills, the more I booked. Now--I've had my work in two gallery shows :)
I also shoot weddings regularly now and actually kind of enjoy it :P You can add me on facebook if you want to see some of my stuff: Juli Penny in the St. Louis, MO network!
