From reading this forum, I have become more and more interested in the world of Digital Photography. For the past 6 months, I have been borrowing a Digital Rebel SLR camera from my mom to learn on. I am finally looking at buying my own camera, and am looking for suggestions. I enjoy taking pictures of my car (although that would not be the cameras only purpose, obviously) and am also looking for a decent lense that would suit that purpose. Finally, does anyone know of a decent photography forum online (or even a book I could buy) to further my knowledge on the more advanced techniques?
I appreciate any help or advice from you guys!!
