Man I love taking pictures!  I've been a photgrahper for a few years now.
I really love photographs as artwork. It is science + art, for sure. Is there a subject you prefer?
I try to go for urban shots, because I'm not stealthy or patient enough to try for nature.  I tr to capture the real human emotion of subjects.
Already impressed ;-) Do you use it in business at all? Or art, film, video production? 
Ah well you do have to eat, right?  I mostly do photos for magazines, both print and web, but I do try to keep a few prize shots for my personal portfolio.  Hopefully I can get a gallery display one day.
I'm rooting for you! Do you do your own developing? I know that's a huge endeavor, with the materials necessary for processing and production.
I got a buddy of mine that will do my developing for me.  He gives me a discount, and I promised him 10% of my eventual gallery opening.
That's friend...and a fan! He obviously believes in your work! Do you prefer color or black+white?
That depends on the shot!  I have him develop 2 copies in each style, I select one for sale and keep the rest in the personal portfolio.  It is, after all, the viewer and beholder that judges what's better, not me.
True, but I know you have your own perspective. Editor's cut/choice as it were. Definitely a difference between commercial and artistic. I know color comes down to an aesthetic -- I do tend to prefer b+w
