I'm an aspiring photographer, I've been a model since I was 12, represented by The Campbell Agency in Texas, one of the top five agencies. I'm 17 and really have a passion for photography, now I was wondering if the Nikon D90 would be good to start off with. I'll be shooting headshots for other models and fashion photography. I'm pretty good with photoshop also. What all do I need to start? A camera, A MacBook (Which I already have), Software (What kind?) and just let me know other stuff that I might need to become a successful photographer. I'm also pretty good with web design so I can build my own website.
