Hi, I'm a freelance photographer in New York. I've been doing it for roughly six years and use a variety of Canon gear. I shoot a pretty broad spectrum of stuff: events, commercial stuff, fashion portraits, boudoir, and some product photography. I'm almost entirely self-taught and photography is my business and my life.
I'd be happy to write some tutorials or do a Q&A or just write about specific things if you guys are interested. You can check out my work here:

A copy of it probably came with your camera. Take a look through the CDs that came with your camera. you can download it if you don't have it. http://download.cnet.com/Photoshop-Camera-Raw/3000-12511_4-10588140.html If you're not shooting in RAW format start right now. Go change your camera setting as soon as you read this.
