I love shooting people and exploring all that they have to offer, the happiness, sadness, mixed emotions and everything else that comes with being human... I would not leave my house looking to photograph butterflies or plants unless I'm getting paid for it (LOL! no diss). It's just not my thing. I always gravitate towards people because they will always surprise you with their infinite range of emotions and that can be very exciting.
I use 1 camera and 1 lens for all my shoots unless specifically asked by the client. My gear is a Nikon D300s & 17-55mm lens. I get lots of emails with this question and I will usually joke by saying "I'm a Nikonian from a planet called NIKON" I shoot with a Nikon because of their superior ergonomics and because it was the first brand I purchased. In photography one usually sticks with the brand they've already invested in. To be honest I don't buy too much into the major brands competition and I can care less about the new/fancy features coming out and all of that. I just need something good enough and reliable because at the end of the day it's really not about that camera, it's what can be done with it.
Professionally, I admire lots of people out there. I believe everyone has something to contribute into this big pot called the creative society. But personally, very few create the kind of work I'd love to learn from. I love Kimiko Yoshida's self portraits and my man Barron Claiborne awesome body of work.
