Good advice so far.
Hey, everyone starts somewhere...
at some point, Richard Avedon picked up a camera for the first time and probably didn't know what an f-stop was.
"Hey, Avedon, put the fucking camera down if you don't know how to use it!"
I always chuckle when I see threads that tell people to stay out of the business when they have a question.
With that said, "Stay the fuck out of the business! We don't need more competition!"
Best of luck...
